  • In one episode of Adam Ruins Everything, Adam's lecturee of the week turns out to be a fan of the show. Adam offers to let her do his usual intro, which she happily does before remembering exactly what she's in for.
    ”Hi! I'm Winnie Jones, and this is Adam Connover, and I’m on Adam Ruins Everything! ...Uh-oh.
  • In the Agents of S.H.I.E.L.D. episode "BOOM", FitzSimmons are investigating the bombing of Senator Ellen Nadeer's office before realising that the "bomb" was an Inhuman who underwent Terrigenesis and immediately exploded. Fitz immediately questions how Shockley survived the explosion, causing both to realise that he must have been the exploding Inhuman and rush down to the hangar just in time to warn Daisy and Director Mace and eject Shockley from the Zephyr before he explodes again.
  • All in the Family:
    • In the episode "Archie in the Lock-Up", after Michael gets back from a protest that had turned ugly, Edith and Gloria ask him where's Archie, who they had guilted into going after him.
      Michael: Yeah, but Gloria, how could he find me? I mean, the place was a madhouse, with people running around, yelling, screaming, the cops arresting everyone. (Beat as his eyes widen in realization) Oh boy.
    • Another episode plays this for laughs. Edith has Archie on a healthier diet per his doctor's orders, which is already making him grouchier than usual. He takes his anger out on Mike for separating his food before eating it, explaining that the best way to enjoy a meal is mixing everything together. Archie goes on to describe how this makes the sandwich the perfect food...and soon works himself into such a hunger that he declares "I gotta have a sandwich, Meathead!" Cue him running to the kitchen.
    • In Season 8, when Archie buys a saloon, Mike has trouble understanding how he could mortgage the house to get the money without getting an uncooperative Edith's signature...at which point he realizes that Archie forged it.
  • Angel:
    • In "City Of", Cordelia is invited to the home of Russell Winters. Taking note of the fact that the Big Fancy House has no mirrors and numerous curtains, Cordy quickly realizes that her host is a vampire... and doesn't even finish talking before she realizes how much danger she's in. Thankfully, Angel shows up Just in Time.
      Cordelia: I finally get invited to a nice place with no mirrors and lots of curtains ... hey, you're a vampire!
      Winters: What? No, I'm not.
      Cordelia: Are too!
      Winters: I don't know what you're talking about.
      Cordelia: I'm from Sunnydale! We had our own Hellmouth! I think I know a vampire when... I'm... alone with him ...in his... fortress-like home...
    • In "Dear Boy", when Angel is believed responsible for the murder of Mr. Kramer, Kate storms the Hyperion with a SWAT team to arrest him, firmly convinced that Angel is evil and always will be evil. However, Gunn asks if Mr. Kramer's wife DeEttanote  actually invited Angel into the house; Kate responds that no, of course Angel wasn't invited in... and as soon as those words are out of her mouth, she realizes that Angel is innocent, since Angel couldn't have entered unless he was invited inside or the real owners were already dead.
      Cordelia: Okay, okay, let's not get off track here. We want to find Angel as much as you do.
      Kate: No, you don't. You want to protect him even though he's lost it: he stalked that woman because he thought she was this Darla from his past. She begged him to stay out and he knocked down the door and killed her husband. I've read about him, too, I know who he is and I know he hasn't changed.
      Gunn: No, he hasn't, he's still a vampire.
      Cordy: Gunn - not helping.
      Gunn: So, how'd he get in the house? She invite him in?
      Kate: Of course she didn't in... (Stunned Silence)
      Cordelia: The only way Angel could get in that house uninvited is if the real owners were dead. It's what he was saying all along; she isn't DeEtta Kramer!
    • In "Guise Will Be Guise", Wesley mentions that the wizard Magnus Bryce is having a birthday party where he'll make tributes to the goddess Yeska, and Angel says Yeska isn't a goddess, she's a Davric demon.
      Wesley: Davric demons eat live sacrifices, generally girls. They grant huge power to the person who offers the sacrifice on their 50— [realizes Magnus is going to sacrifice his daughter]
    • In the episode "Calvary", Wesley, Gunn, Connor and Fred are tracking Angelus through the city while Cordelia and Lilah are back at the hotel.
      Connor: Angelus would want to feed, but his scent ends here, and it's not a highly populated area.
      Gunn: It ends here? Somebody pick him up?
      Connor: He would go to the place where he could wreak the most damage.
      Wesley: Which doesn't necessarily mean highly populated.
      Fred: He doubled back.
  • Babylon 5: In "A Tragedy of Telepaths", G'Kar swipes some fresh spoo (a Centauri foodstuff) off of a serving cart and offers it to Londo, who turns his nose up at it: spoo is apparently supposed to age first. Only Narns like G'Kar can stomach it fresh, and G'Kar is supposedly the only Narn in the Centauri imperial palace, as he idly remarks... before having a sudden realization that a serving cart of fresh spoo means he probably isn't and demanding from Londo what's in the part of the palace where the cart was headed. They discover his former aide Na'Toth, still imprisoned in a palace dungeon more than a year after the Centauri withdrew from the Narn homeworld.
  • The Barrier: While having an evening walk with Julia, his deceased wife Sara's identical twin sister, Hugo recognizes a closed down night club style bar. Julia recognizes the bar as well, fondly remembering it. Hugo tells Julia that the place is where he first saw Sara and fell in love with her while watching her dance. Due to various circumstances, Hugo was unable to approach Sara that evening and ended up asking her out after running into her elsewhere. He also mentions that while he saw Sara dance multiple times since then, he never saw her dance as she did when he first saw her in the bar again. He then remembers seeing Julia dance to street musicians earlier that day and the Identical Twin Mistake penny drops.
  • Batman (1966) had an episode featuring Gotham Museum sponsoring a "Great Comedians" exhibit. Batman is called in when someone installs a crude statue of the Joker in the middle of the exhibition; he urges the museum guards to escort everyone outside and seal off the building, as it's clearly some kind of trap. The guards follow orders and begin bragging about the extremely high-tech security measures—once the system is activated, it's impossible for anyone to get in or out of the museum. Batman realizes what this means and has the guards repeat themselves so they catch on, too—the Joker wasn't planning to break into the museum. He and his thugs are already inside, and now no one can get back in to stop them. Sure enough, the Joker bursts out of the statue, calls to his minions (who are hiding in the other sculptures), and heads for the rare gem display.
  • Best Friends Whenever: In the episode "Girl Code", Shelby asks two guys to build a website for her. The two guys have a crush on Shelby and are distracted by her asking how to figure out if a girl likes them. Shelby, being Oblivious to Love, tells them that when a girl likes a guy she will touch his arm (which Shelby does). One of the guys tells her that he likes blondies and Shelby still doesn't realize they are talking about her until Cyd tells her.
    Shelby: I asked them if they like brownies. They told me they like blondies. (beat) Oh my god, Cyd! How did I not see this coming?!
  • A variation occurs in The Big Bang Theory season 4 episode "The Hot Troll Deviation" as the conclusion to that episode's B-plot regarding a feud between Sheldon, Raj, and a Brobdingnagian desk:
    Leonard: Oh, God, what's that smell? (Knocks on Sheldon's office door)
    Sheldon: (Comes out wearing a gas mask) Yes?
    Leonard: What are you doing in there?
    Sheldon: I'm making hydrogen sulfide and ammonia gas. Just a little experiment in pest control.
    Raj: (Steps out of the office) It's not gonna work, dude! I grew up in India — an entire subcontinent where cows walk in the street, and nobody has ever had a solid bowel movement.
    Sheldon: Well, we'll just see how long you can hold out.
    Raj: Well, we'll just see how your noxious gas fares against my cinnamon-apple-scented aromatherapy candles. (goes back into the office)
    Leonard: Didn't you say you're making hydrogen sulfide gas?
    Sheldon: Yes.
    Leonard: Isn't that flammable?
    Sheldon: Highly. (Leonard gives him a concerned look) Oh, dear.
    (BOOM)
    Raj: (steps out completely covered in soot) This is not over.
  • Blackadder:
    • In "Head", after the title character learns that Baldrick has mistakenly executed Lord Ponsonby: "And when the Queen gets back from seeing Ponsonby, we'll... ohh, God!"
    • In Blackadder's Christmas Carol, Blackadder's change of heart towards being bad means that he slams the door on Queen Victoria. In fact he does it without even checking who she is, when she had come to give him his enormous cash reward for being the kindest man in London.
      Blackadder: Look, whenever the Queen goes anywhere she leaves behind her royal seal.
      Baldrick: You mean like this one?
      Blackadder: Yes, exactly like that on-
  • Blindspot:
    • In "Why Let Cooler Pastures Deform", the FBI is raiding a house, worried that their phones are scrambled. They're thus thrown when suddenly, their communicators start working again.
      Reade: Why would Sandstorm turn their scrambler off now and risk letting a signal out?
      Kamal: So they can get a signal in... Get out, it's a trap!
    • Played for laughs in "Artful Dodge" as semi-reformed crook Rich talks to an FBI agent overseeing his deal working with the team for his freedom. Asked how he helped out Patterson in an earlier episode, Rich gushes on how he hacked her computer, used secret passages he's built throughout the building, dropped a virus into the mainframe, knocked out a security guard and made a fake bomb.
      Rich: What are you writing down?
      Reviewer: Oh, just adding up how many years you've tacked onto your prison sentence based on that story alone. Now tell me more about the virus.
  • In Boy Meets World, when the attempt to have a no-strings-attached sex between Angela and Shawn fails upon Shawn telling Angela "I love you", Angela accuses Shawn of being too emotionally invested. Shawn tries to defend himself in protest, only to realize Angela is right — and then some.
    Shawn: Aw man, I Cory'd this up didn't I?
    Angela: You had to go and get heavy, Shawn - didn't you?
    Shawn: No, I'm not getting heavy, Angela, I just think that an emotional commitment is the proper foundation for OH MY GOD I'M BOTH OF THEM!
  • The Brittas Empire: Laura does this in "Brussels Calling" upon realizing the staff had just accidentally created a garbage bomb:
    Laura: Colin... had thirty bags of weedkiller by the emergency exit, and they weren't there when I came back. What's he done with them?
    Linda: I think he threw them away. Mr. Brittas told him to. I think that's how he got confused about the fire bucket. You see, he-
    Laura: Colin threw away a hundred weight of weedkiller where?
    Carole: It's alright, put it in a dustbin. I saw him when I took 'round the icing sugar.
    Laura: What icing sugar?
    Carole: Well, Gavin rang from the kitchen to ask if he could borrow some, and I happened to have an extra packet.
    Laura: What would Gavin want sugar for? He's got a cupboard full of it.
    Julie: Yeah, but the rats ate that. Well, some of it. That's why Brittas told him to throw it away.
    Laura: He put weedkiller... sugar. (Beat) He couldn't have... could he? [Mass "Oh, Crap!" as Laura, Linda, Carole and Julie race out towards the potential garbage bomb]
  • Used several times on Buffy the Vampire Slayer.
    • In "The Puppet Show", Buffy and Xander have assumed that Willow will be targeted by a demon that wants to steal a good brain. Willow idly wonders if they should warn Giles, to which Xander responds "Don't worry about Giles, I mean he is really... smart." Cue them running out of the library.
    • In the second season premiere "When She Was Bad", the Scoobies have discovered a plot by the Master's order to bring the Master Back from the Dead using a Human Sacrifice, said sacrifices being those "closest" to the Master. Shortly after Buffy leaves for the Bronze for an obvious trap, Giles finishes translating the ritual and discovers that "closest" to the Master actually means those who were physically present when the Master diednote . Giles doesn't even finish his sentence before he realizes what this means. A double dose of this trope follows when he sees vampires crowding onto the mezzanine level, and realizes the "trap" was actually meant to lure Buffy away so the Order could capture them without interference.
      Giles: It is a trap. It just isn't for her.
    • "Primeval": When the group is reconciling after the events of "The Yoko Factor", Buffy lets the others come to their own conclusions to realize that it was Spike who played them off against one another.
      Giles: Well, Spike can be very convincing, and... we're very stupid.
    • And before this in the same episode, Spike and Adam are discussing the success of Spike's plan — he has successfully separated Buffy from her friends, now they just need Buffy to work with her friend to decode the information disc. Adam points out the contradiction here. According to the episode commentary, this was actually a bit of an Author's Saving Throw from when they had the same realization.
      Spike: Our little witch gives her the info and pop — Alice heads back down the rabbit hole.
      Adam: The witch.
      Spike: Uh, Willow. About so high, perky, good with math. Natural choice.
      Adam: Her friend.
      Spike: Right.
      Adam: One of the friends from whom you've so efficiently separated her.
      Spike: Damn right I did. You should've seen 'em. They won't be talking to each other for a long, long... [beat] Hang on. I think I might have detected a small flaw.
    • In "Blood Ties", Dawn breaks into the Magic Box at night with Spike in an attempt to figure out what the Key that Buffy and the rest of the Scooby Gang have been talking about is. Reading Giles' journal, she starts to realize that all of the signs of the Key correspond to things that she's experienced in the last few months... even before she gets to the part explicitly stating that the Key's keepers gave it the form of a sister for the Slayer. Cue Heroic BSoD.
    • In "Shadow", Glory buys supplies for a dangerous summoning from The Magic Box before Giles actually knows what she looks like - he only has Buffy's vague description of a superpowered girl. Later, Anya goes over the receipt and is horrified at what Giles sold, leading to an exchange where the gang realizes that they sold items for a dangerous summoning ritual to the Big Bad:
      Anya: You sold someone a Khul's amulet and a Sobekian bloodstone!
      Giles: Yes, I believe I did.
      Anya: Are you stupid or something?!
      Giles: Allow me to answer that question with a firing.
      Xander: She's kidding! An, we talked about the employee-employer vocabulary no-nos. That was number five.
      Anya: You never sell these things together, ever! Bad news! Don't you know about the Sobekites?
      Willow: Oh! I do. It was an ancient Egyptian cult, heavy into dark magic.
      Tara: And the Khul's amulet, wasn't that a transmogrification conduit?
      Anya: Damn straight!
      Giles: Be that as it may, I still see no reason for concern. I mean, the Sobekian transmogrification spells were lost thousands of years ago. And besides, the young woman to whom I sold them would have to have had enormous power- [Stunned Silence]
      Willow: ...Young woman?
      Giles: Oh, dear Lord.
    • In "Tough Love", after Glory attacks and Mind Rapes Tara, Willow is furious and planning to take revenge on Glory, but Buffy seemingly manages to talk her down, insisting that doing so would be potentially suicidal. Later, when talking to Dawn and Spike about it, Spike, understandably skeptical, points out that an angered witch, especially one as strong as Willow, is not so easily reasoned with, and if Glory had attacked his loved one, he would have reacted the same; then Dawn asks Buffy how she would react if Glory had attacked and Mind Raped her. Cue realization on Buffy's end.
  • Charmed (1998):
    • The episode "Spin City" mixes this with a healthy dose of Genre Savvy. The Monster of the Week, a spider demon, wants to kidnap Piper and feed on her magic. To achieve this goal, she infects Chris with her venom, slowly transforming him into her minion. Paige and Phoebe lock Chris in the basement to keep an already-webbed-up Piper safe; later, the sisters are chatting with Leo in the kitchen when Phoebe's empathic powers kick in, prompting her to lash out at the Whitelighter with Chris's resentment. Leo is surprised that her abilities can reach the basement...and Paige quickly deduces they haven't—Chris has escaped. They dash into the living room and find Chris, now able to transform into a spider, kidnapping Piper.
    • In "Sin Francisco", a demon is infecting humans with the concentrated essence of the Seven Deadly Sins. He throws four orbs at Prue, Piper, Phoebe, and Leo, who seem unaffected and try to go about taking care of the demon. One scene later, though, Phoebe is trying to talk her history professor into sleeping with her, Piper is maxing out her credit cards to buy fancy clothing while drinking champagne, and Leo is vegging out on the sofa. Prue quickly deduces that they've been infected with Lust, Gluttony, and Sloth, respectively. Later, the trope is played again when the police chief points out the Prue is acting dangerously reckless and conceited; Prue agrees, then realizes that this means that she's been hit with Pride, as the sins' whole M.O. is to gradually corrupt the infected to self-destructive acts.
    • In "That 70s Episode", Prue, Piper, and Phoebe are sent back in time to 1975 and are explaining themselves to their then-living mother and grandmother:
      Grams: How old were you when you got your powers back?
      Piper: We just got them.
      Grams: What? I unbound your powers without having broken the pact? Why would I do that? I mean unless I died which of course would automatically unbind your powers... (pause) I guess I'm not going to make it to the next millennium, huh?
  • Cheers has one right in the first episode, when Diane insists she doesn't need Sam's pity offer of becoming a waitress. She's got all sorts of options waiting for her. Then Sam asks Carla to recite the complicated drink order she just got, and Diane starts doing it for her. She trails off when she realizes what she's doing.
    • In another first season episode, famous Bostonian Thomas P. "Tip" O'Neill, then the Speaker of the U.S. House of Representatives, drops by Cheers As Himself for a beer. Norm is out of the room when the patrons realize who O'Neill is; when he gets back, Cliff tricks him into badmouthing Congress. O'Neill casually remarks that he's the Speaker, and Norm laughs it off: "Don't be ridiculous! That would make you Tip O'Neill, and me...a horse's butt." O'Neill gets the last word—"You said it, not me."
    • The series 5 opener has Sam explain he's going out for an evening, confusing Frasier and Carla, since he'd just been dumped by his current girlfriend, Janet Eldridge, so who would that leave? They come to the realization he's going to meet Diane, and scream in horror.
  • Cobra Kai: In season 3 episode 6, Johnny has enlisted Miguel to help him come up with a response to Ali's Facebook message. Johnny wants to send a Wall of Text in ALL CAPS detailing every last thing he's done for the last 35 years, which Miguel mistakes for a novel and is dumbfounded that Johnny actually wants to send.
    Miguel: Ali? Like, the Ali? This is huge. This is huge! This is so… But I mean, you're not gonna send that, right? You cannot send her that message.
    Johnny: Why not?
    Miguel: Because it's, like, 80 pages. In all caps.
    Johnny: I have 35 years' worth of stuff to say, all right?
    Miguel: OK, yeah, yeah. Yeah. But shorter messages are way cooler. Like, this just looks desperate. And a little creepy. Sending her this would be like if you… like if you liked all of her photos.
    Johnny: [makes a guilty face]
    Miguel: Oh, no. Oh, no!
  • On Designated Survivor, Hannah is checking with computer hacker buddy Chuck at his apartment when she notices an odd smell.
    Chuck: Yeah, there was a gas leak in the building earlier. A guy from DC United checked it out, said it was fine.
    Hannah: Chuck, DC United doesn't check out gas leaks. The fire department does. Out, now!
    • In season 2, tapes of Kirkman's therapy sessions are leaked, calling into question his ability to make decisions. Lyor is annoyed that various members of the Cabinet aren't returning his calls, figuring they're staying out of this. His secretary reports how she's heard the Cabinet are all talking to Vice-President Darby. Lyor wonders why the Cabinet would be meeting with the VP in total secrecy...then sees the news. He races in to warn Kirkman of how the Cabinet are prepared to invoke the 25th Amendment to remove Kirkman from office.
  • Diagnosis: Murder: In "The Last Laugh", Mark, suffocating after being trapped in a room filling with laughing gas, the weapon of choice for the Killer of the Week, called both his assistant Delores Mitchell and hospital administrator, Norman Briggs, but because he was laughing and speaking in a comedic way because of the laughing gas they assumed that he was joking, prompting Norman to go to confront Delores about Mark's action, at which point they realize that he had called both of them and would only have done that if he was serious.
  • In one episode of The Dick Van Dyke Show Rob calls Laura and disguises his voice to see if she recognizes him. When it seems like she doesn't, he starts flirting with her as a joke. He only realizes the implications afterwards:
    Rob: I tell you, I fooled her! She was entranced! You know what she thought? She thought she was flirting... with a complete stranger...
  • Doctor Who:
    • "The Pirate Planet": The Captain uses his technology to loot the planet Calufrax and has constructed a psychic-jamming device to defeat the telepathic Mentiads. The Doctor insists that the device can't work because it requires very rare minerals to supply power.
      The Doctor: And as far as I know, they occur naturally on only one planet, and that's...
      Fibuli: Captain, the crystals from Calufrax.
      The Doctor: Calufrax! ...My biorhythms must be at an all-time low.
    • "Remembrance of the Daleks": The Seventh Doctor has just disabled a Dalek transmat device and mentions that it'll slow the Daleks down until the "operator" can restore it.
      Ace: Operator?
      The Doctor: [distracted with the transmat] Yes, the Daleks usually keep an operator on station in case of any malfunctions.
      Ace: Which would be... another Dalek?
      The Doctor: [realizing] ... Yes.
      Dalek: STAY WHERE YOU ARE! DO NOT MOVE!
    • "The Doctor Dances": The Doctor is talking about how the Creepy Child leader of the gas-mask zombies has "the power of a god". Then he realizes that, earlier, he got the zombies to back off by ordering all of them to go to their rooms... and he, Rose and Jack are in the Child's room... they turn around to see him standing there.
    • "The Impossible Planet": The Doctor explains to the staff of Sanctuary Base 6 how he and Rose got to their remote outpost and where the TARDIS is parked... in a section of the base that was just lost due to an earthquake that collapsed part of the planet's surface.
    • "The Runaway Bride": The Doctor, when he realizes that Donna has been dosed with huon particles and the device he gave her to hide her from the robots pursuing her therefore won't work:
      "Huon energy doesn't exist anymore, not for billions of years. So old that... [looks at Donna] …it can't be hidden by a bio-damper!" [runs to a window and sees the evil robot Santas approaching]
    • "Partners in Crime" has a variant where the explanation is done by someone who's trying to get the point across to the person who does the Oh, Crap! that they're in danger:
      The Doctor: Listen, I saw the Adiposian instructions. They know it's a crime, breeding on Earth, so what's the one thing they want to get rid of? Their accomplice!
      Miss Foster: Oh, I'm far more than that. I'm nanny, to all these children.
      The Doctor: Exactly! Mum and Dad have got the kids now, they don't need the nanny anymore!
      [Foster has one second to realize what he means before the levitation beam shuts off and she plummets with a SPLAT!]
    • "Forest of the Dead": The Doctor, after managing to talk to the Vashta Nerada, is so preoccupied with deducing, out loud, how they came to infest the Library that he doesn't pay attention to Other Dave until after he's started repeating himself a lot. It's not until he says the same thing four times that the Doctor catches on.
    • "A Good Man Goes to War": The Eleventh Doctor runs into this when it turns out that Amy and Rory's daughter Melody Pond is part Time Lord, which Vastra suggests was a result of her being conceived on the TARDIS. He insists that this can't be possible as, between the various cosmic retcons that went on the previous season, the first time they were on the TARDIS together in this version of reality was the night after their wedding — oops.
    • A milder example takes place in a flashback scene in "Let's Kill Hitler", when teenage Amy explains to Rory why he has to be gay; "In the whole time I've known you, when have you shown the slightest interest in a girl?" (Penny in the air...) "I mean I've known you for what, ten years? I've seen you practically every day. Name one girl you've paid the slightest bit of attention to... Oh my God. Rory!" (And the penny drops.)
    • "Asylum of the Daleks": The Doctor notices the humans with Dalek eyestalks were created by nanogenes that infect living or dead human beings. Amy realizes he said "...or dead" in a room full of dead bodies. The Doctor continues to explain until he realizes he's also in the room with dead bodies. Uh oh.
    • The Doctor spends "Robot of Sherwood" convinced there's no way Robin Hood is who he says he is. When he discovers this is tied in to alien robots, the Doctor naturally jumps to the conclusion Robin is one of them and accuses the Sheriff of creating this.
    The Doctor: Robin's one of yours.
    Sheriff: What did you say?
    The Doctor: He's one of your tin-headed puppets, just like these brutes here.
    Sheriff: Robin Hood is not one of mine.
    The Doctor: Of course he is. He's a robot, created by your mechanical mates.
    Sheriff: Why would they do that?
    The Doctor: To pacify the locals, give them false hope. He's the opiate of the masses.
    Sheriff: Why would we create an enemy to fight us? What sense would that make? That would be a terrible idea.
    The Doctor: Yes! Yes, it would. Wouldn't it? (realizing) Yes, that would be a rubbish idea. Why would you do that?
    • "The Zygon Invasion": Clara and Jac, a UNIT official, are investigating an underground Zygon bunker full of pods.
      Clara: Look, they're here. They're growing duplicates of us. We have to destroy them. I've seen this happen before. It happened to that little boy. They took his parents and then they took him.
      Jac: But I don't see how these are duplicates. That's not how Zygons work. They don't grow duplicates. They kidnap the originals so, these... [sees "Clara" turning with a wicked smile] These are the humans! IT'S A TRAP!
    • "Arachnids in the UK": The Doctor begins to piece together the chain of events from the spiders being experimented upon to the lab waste being brought to the secret landfill under the hotel... and suddenly realizes the mine shaft everyone's standing in is actually a giant spider nest.

  • Firefly plays with this in the episode "Out of Gas". The crew of Serenity is in a dire situation with the life support system failing. They are in a deserted region of space with little chance of any ships wandering around there. Wash has lost all hope, when Mal suggests a way to boost the SOS signal.
    Wash: What do you expect me to do, Mal?
    Mal: Whatever you have to. And if you can't do it from here, then get a suit on and go outside on the side of the boat...
    Wash: And what? Wave my arms around?
    Mal: Wave your arms around. Jump up and down. Divert the nav sats to the transmitter. Whatever.
    Wash: Divert the — right! Because teenage pranks are fun when you're about to die!
    Mal: Give the beacon a boost, wouldn't it?
    Wash: Yes, Mal, it would boost the signal. But even if some passerby did happen to receive, all it would do is muck up their navigation.
    Mal: Could be that's true.
    Wash: Damn right, it's true. They'd be forced to stop and dig out our signal before they could even go anyplace.
    [beat, Mal waits for Wash to get it]
    Wash: [still yelling as if he's angry] Well maybe I should do that, then!
    Mal: [yelling back] Maybe you should!
    Wash: Okay!
    Mal: Fine!
    Jayne: [enters the room] What the hell do you two think you're doing? Fighting at a time like this? You'll use up all the air!
  • In the Flight of the Conchords episode "Unnatural Love", Jemaine does this after the Victoria carriage driver tells him that he doesn't go to New Jersey like his shady Australian girlfriend Keitha said.
    Jemaine: She said she'd done it before. (He realizes that Keitha tricked him). Oh no. Oh no.

  • Sherlock, the eponymous character often does after a Sherlock Scan.
    • At the end of "A Study in Pink", when Sherlock agrees to help Lestrade figure out who killed Jeff Hope.
      Sherlock: The bullet they just dug out of the wall is from a hand gun. A kill shot over that distance from that kind of a weapon? That's a crack shot you're looking for, but not just a marksman. A fighter. His hands couldn't haven't shaken at all, so clearly he's acclimatized to violence. He didn't fire till I was in immediate danger, though, so strong moral principle. You're looking for a man probably with a history of military service, nerves of steel...
      [Sherlock looks over at John, and realizes that he was the shooter]
      Sherlock: Actually, you know what? Ignore me.
      Lestrade: Sorry?
      Sherlock: Ignore everything I just said. It's just the...the shock talking.

      Sherlock: I'm not the first.
      John: What?
      Sherlock: Someone else has been here. Someone broke into this flat. He knocked that vase, just like I did. Size 11. He was tall. But not heavy. Long, thin fingers. Our acrobat.
      John: What are you saying?
      Sherlock: Why didn't he close it when he left—? [Beat] Oh, stupid, stupid. Obvious! He's still here.
    • In John and Sherlock's Christmas party in "A Scandal in Belgravia" when Sherlock does his Sherlock Scan on a Christmas present that Molly brought, smugly trying to explain what was on Molly's mind when she wrapped it. Then he realizes who she brought it for.
      Sherlock: Oh come on. Surely you've all seen the present at the top of the bag. Perfectly wrapped with a bow. All the others are slapdash at best. Must be someone special then. Shade of red echoes the lipstick. Either a subconscious association or one that she's deliberately trying to encourage. Either way, Miss Hooper has love on her mind. The fact that she's serious about him is clear from the fact that she's giving him a gift at all. That all suggests long-term hopes, however forlorn. And that she's seeing him tonight is evident from the make-up and what she's wearing. Obviously trying to compensate for the size of her mouth and breasts.
      [Sherlock sees the tag on the present, which reads "Dearest Sherlock, Love Molly"]
      Molly: You always say such horrible things. Every time. Every time...

    McKay: What?
    Sheppard: How long do you think a Wraith could feed on all those humans back there?
    McKay: Well, they're capable of hibernating for hundreds of years at a time, but, I mean, think about it. Ten thousand years ago was roughly the dawn of human civilization.
    Sheppard: So there's no chance that uh—
    McKay: No, no, no, no, no. Are you kidding? [beat] Well... maybe.
    Sheppard: [annoyed] McKay.
    McKay: No. No. No living thing could survive that long under those conditions. It's ridiculous.
    Sheppard: Okay.
    McKay: That would require an incredible power source capable of sustaining the stored humans in suspended animation almost the entire time.

  • Walker, Texas Ranger has this occur on a few occasions:
    • Both Trivette and Pastor Roscoe Jones are hit with this in Season 6's "The Soul of Winter", where the Rangers contend with Stan Gorman, a former military officer-turned-leader of a neo-Nazi group known as the Sons of the Reich, who had killed a kid named Rodney Summers outside the First Christian Church of Dallas, where Roscoe became its new pastor since the death of Trent and Tommy's father, Thunder Malloy. Gorman and his men killed Summers by mistake, because their intended target was Roscoe's son, Adam; both Adam and Rodney were late for the sermon that morning due to delivering food baskets to needy families, and Gorman's motive was to get Roscoe to resign. While Trivette digs up information on Gorman after Carlos picks up a piece of his literature at Eastside High School (where Adam and Tommy attend), he finds he was stationed at Fort Hood with Thunder and Roscoe, who, at the time, served as chaplains. When the Rangers, Trent and Carlos apprise Roscoe of the situation, Roscoe quickly concludes what's going on, demands that Adam be brought home immediately and backstories between him and Gorman during their time at Fort Hood come to light. While Roscoe explains how he put Gorman in prison, Trent and Carlos stop the latter's men before they could kidnap and kill Adam and Tommy.
      Trivette: All right, and they even have their own website. It's incredible. You can donate to the cause with a credit card. Buy your T-shirts, hats, emblems, jackets, Nazi insignia, banners, instruction manuals... Virtual cyber-supermarket of hate.
      Walker: Does it say who's behind it?
      Trivette: Not yet. Let me see here. All right, here we go. "The new Fuhrer for the '90s: Stan Gorman." Huh. Wrote a book. How about that? Our America. Fifty bucks. Membership in the Sons of Reich with every purchase.
      Carlos: Incredible.
      Trivette: Not really. Hate sites have more than doubled in the past year. This one came on-line... September.
      Walker: That's about the same time the hate crimes started. See what else you can dig up on this Gorman character.
      Trivette: All right. [it's not long before he digs up how Gorman knows Roscoe] Hey, didn't Roscoe say he met Thunder Malloy when they were Army chaplains at Fort Hood?
      Walker: Yeah, why?
      Trivette: You're never gonna believe this.
      [later at the church when the two Rangers, Carlos and Trent apprise Roscoe of the situation]
      Roscoe: Stan Gorman?!
      Trivette: Leader of the Sons of the Reich.
      Trent: What's going on? Do you know him?
      Roscoe: Adam! Get up to that school and bring him home right now!
      Trent: What?
      Roscoe: Don't ask questions, just do it!
      Trent: Okay.
      Carlos: I'll go with him.
      Walker: What's this all about, Roscoe?
      Roscoe: Walker, the bullet that killed Rodney Summers was meant for my Adam!
    • "Special Witness" (Season 7) detailed the Rangers protecting a Special Olympian named Sally (played by Andrea Fay Friedman) from being assassinated by Morris Foley (a mob boss) and his federally-wanted hired hitman, Donovan Riggs (played by Gary Busey), after she witnesses the latter stab Trent to prevent him from testifying against Foley in court, and was surprisingly successful in identifying him. Trent was the only witness in Foley's trial, and without his testimony, Alex has no case to build against him, but he luckily pulls through in time after Walker arrests Riggs. Before Riggs could go on to kill Sally, he first kills the police sketch artist, Gloria Doran, then steals her car, stuffs her body in it and leaves it abandoned, where a dog walker found blood dripping from the trunk. When Walker and Trivette are called to the crime scene, it doesn't take long for Walker to figure out who did it, as well as who the assailant's next target will be!
      [At the site where Gloria's body was discovered, as the crime scene unit cleans up and the coroner prepares to take her body away, Walker and Trivette pull up in the Ram with its strobes flashing]
      M.E. Mary Williams: Walker, Trivette?
      Walker: Mary, what have we got?
      M.E. Williams: She's been dead about 12 hours.
      Trivette: Do you have a cause of death?
      M.E. Williams: Well, there are a number of superficial wounds, but the cause of death appeared to be a stab wound to the chest. Now, I'll know more after the autopsy, but from the amount of blood lost, I'd say the aorta was completely severed.
      Walker: Any ID on the victim?
      M.E. Williams: I thought you knew. It's Gloria Doran, the police sketch artist. [Walker and Trivette look in the trunk of Gloria's car and examine her dead body]
      Trivette: Why would somebody kill Gloria?
      Walker: Sally! [he and Trivette race back to his Ram to track down Riggs before he could kill Carlos and Sally]
    • "Suspcious Minds" (Season 7) has the Rangers using info from undercover cop Georgie, who's embedded with mob boss Sonny Tantero.

    Trivette: Johnny Boy, you gotta wake up. We got you, all right? Illegal weapons, intent to sell, resisting arrest. (to Walker) There's something else...
    Walker: Attempted murder on a peace officer.
    Johnny Boy: Attempted mur...? Are you guys nuts?
    Trivette: No. Javier pulled the trigger, but the act was committed during the commission of a felony. Oh... A felony involving you, so in the eyes of the law, pal, you're just as guilty.
    Johnny Boy: All right, what do you want?
    Walker: Sonny Tantero.
    Johnny Boy: Sonny Tantero? I don't do business with that whack job. I got these guns from Big Joe McArthur.
    Trivette: ...Oh, my God.
    Walker: It was a set up.
    • Season 9's "6 Hours" has the Rangers dealing with Theodore McNeely, the traitorous bodyguard of the wealthy 16-year-old Heather Preston, who had kidnapped her and planned to murder her live on the internet within six hours. The start of the episode has Alex being honored for her work at the HOPE Center, but a group of gunmen hired by McNeely crash the party to keep the Rangers and Heather's father, Tim, distracted long enough for him to escape with his hostage. After the Rangers take down the gunmen, and then find the Prestons' chauffeur dead in the parking garage (having been shot to death by McNeely before he escaped with his hostage), leaving another bodyguard to wonder why McNeely isn't answering his phone, Walker quickly figures out what's really going on, just before the scene shifts to McNeely's hideout (at which point the Episode Title Card is shown) and Heather is restrained to her death chair:
      Walker: I can't figure this out, Alex.
      Alex: What happened here?
      Walker: It has all the looks of an attempted kidnapping.
      Alex: Yes, but the obvious choice is Mr. Preston.
      Walker: Yeah, but they didn't try to hit us. They shot above us and then retreated. Why didn't they try to take him? Where's Heather? Mr. Preston, where's Heather?
      Tim: McNeely has her. He got her out.
      Walker: Can you call him?
      Thompson: McNeely. McNeely? Dean. They're not answering.
      (Beat)

      Sydney: Stay down! (holds a gunman at gunpoint)
      (Walker, Trivette, Alex, Tim and Thompson go into the garage and find Dean, the limo driver, dead)
      Tim: Oh, my God! What happened?! Where's Heather?!
      Trivette: Where's McNeely?
      Thompson: McNeely! McNeely! McNeely!
      Trivette: Why isn't he answering?
      Walker: It was a diversion, Trivette.
      Tim: A diversion for what?
      Walker: To get Heather out of there.
      Tim: But McNeely's got her.
      Walker: I know.
      Trivette: You think he kidnapped her?
      Walker: Yeah, I do.
