* Multiple times in ''Series/PushingDaisies'', since Ned and Chuck can't actually touch directly.

* Season 2 of ''Series/TheWire'' has a lot of this, because of its secondary focus on the prison lives of D'Angelo and Avon Barksdale. D'Angelo and [[MamaBear Brianna]] do a fairly standard open-palmed not-touch; Avon and Stringer Bell fist-bump through the glass.

* This happens at the end of the ''Series/DueSouth'' episode "[[Recap/DueSouthS1E10GiftOfTheWheelman Gift of the Wheelman]]", in a scene where a teenager is visiting his father, who's in prison for bank robbery.
* In the ''Series/VeronicaMars'' episode "[[Recap/VeronicaMarsS01E11SilenceOfTheLamb Silence of the Lamb]]", Mac and her biological mother touch through a car window, letting each other know that they both are aware of her parentage.

* At the end of the ''Series/Charmed1998'' episode "[[Recap/CharmedS2E18ChickFlick Chick Flick]]", Phoebe and her fictional horror-movie crush do this through the fourth wall to say goodbye.
* When Kate goes to visit Neal in prison in ''Series/WhiteCollar'', he tries to do this, but she'll have none of it. [[spoiler:Later, when he watches the security footage, he realizes that she's tapping her leg in Morse code to send him a secret message instead.]]
* At the end of the ''Series/{{Farscape}}'' episode "[[Recap/FarscapeS03E16RevengingAngel Revenging Angel]]", Crichton and D'Argo touch hands apologetically through one of Moya's windows (and Crichton's spacesuit).
* In ''Series/HowIMetYourMother'', Barney does this while visiting a prison inmate in a flashback.

* ''Series/TeenWolf'':
** [[spoiler:Jackson]] the Kanima does this with its first master, [[spoiler:Matt Daehler]]. Since its second master, [[spoiler:Gerard Argent]], became its master with the same gesture sans glass between their palms, it appears that the glass is only a physical barrier and has no effect on the metaphysical aspect of the moment.
** Another example between [[HeterosexualLifePartners Scott and Stiles]] happens in Season 4 when Scott is trapped in a vault, succumbing to a deadly virus and Stiles can't get in to give him the cure. The scene has Stiles pounding against the door ''screaming'' Scott's name, while Scott desperately tries to let him in. Eventually they both collapse to the ground and lie pressed against the door on either side, apparently just waiting to die together if they can do nothing else.
* Fargo and Holly do this at the end of the ''Series/{{Eureka}}'' episode "[[Recap/EurekaExMachina Ex Machina]]", through SARAH's monitor-esque wall. [[spoiler:Since Holly's the victim of an accidental BrainUploading, she's (sort of) ''inside'' the wall.]]
* In ''Series/{{Alias}}'', Sydney and Anna Espinoza repeatedly leave kisses on the glass separating them. They're mortal enemies.

* ''Series/{{Rome}}'': After a sexual scandal, Octavian has his mother Atia confined to her house and forces Marc Antony to leave Rome. Before setting sail, Antony goes to see Atia one last time, and they're forced to exchange final words with a row of soldiers between them.
* ''Series/AgentsOfSHIELD'':
** Simmons is [[spoiler:quarantined]] inside the lab, sitting on the floor with her back to the glass door. [[PlatonicLifePartners Fitz]] sits in the same spot on the other side of the door. Since they can hear fine and they're not even facing each other, this is more an act of solidarity than an attempt to communicate; [[TheDividual they just want to be close together]].
** Versions of this, plus SeparatedByTheWall, continue for most of the episode: Fitz and Simmons talk, work together, and even pass objects through the door, but can't open it [[spoiler:or Fitz and the rest of the ship could be infected. Other variations include [[HonorBeforeReason Fitz eventually simply opening the door and entering the lab to better find an antidote]], and the [[SayMyName pounding-on-the-glass-screaming]] part when Simmons thinks their antidote won't work and Fitz sees her throw herself out of the cargo hold before she can kill everyone. She gets better]].
* The ''Series/Supergirl2015'' episode "[[Recap/Supergirl2015S2E15Exodus Exodus]]" has a non-romantic version between the title character and her sister Alex, [[http://dailydcheroes.tumblr.com/post/158091488148 as seen here.]]
* In the fourth season of ''Series/TheFlash2014'', when [[spoiler:Barry]] is in prison after being framed for murder, he does this with [[spoiler:Iris]]. When he's sure the cameras aren't looking, [[spoiler:he uses his super-speed to [[{{Intangibility}} phase his hand through the glass]] to touch hers]].
* One episode of ''Series/LawAndOrderSpecialVictimsUnit'' features this trope. The team tracks what is initially believed to be a grown man who murders children in a small town. It is eventually discovered that [[spoiler:the murderer is a child himself]], and that his father (who had long been aware of that fact) was hiding him so that the police wouldn't apprehend him. Upon being caught before he can harm another one of his peers, Stabler ask him why he did it. He flatly states "[[ForTheEvulz Because I wanted to!]]". Before the cop car drives away, the boy's father touches the window. The boy follows suit. It's the only shred of empathy we see from him.
* ''Series/StarTrekVoyager'':
** In the pilot episode, "[[Recap/StarTrekVoyagerS1E1Caretaker Caretaker]]", Captain Janeway is talking via SubspaceAnsible to her fiance Mark, ending the conversation by blowing him a kiss and touching her fingers to the viewscreen. Before the episode is over, they'll be 70,000 light-years apart.
** In "[[Recap/StarTrekVoyagerS4E3DayOfHonor Day of Honor]]", Tom and B'Elanna are stranded in outer space, so they can hardly embrace each other as they're stuck inside their EV suits, though they make the best of it.
* ''Series/{{Arrow}}'': The episode "[[Recap/ArrowS4E9DarkWaters Dark Waters]]" has a dark version when Felicity Smoak is trapped in a GasChamber and can be seen silently mouthing a DyingDeclarationOfLove to Oliver Queen as he desperately tries to free her. Fortunately, Laurel [[GlassShatteringSound breaks the glass with her Canary Cry]].

* ''Film/{{Morgan}}''. Morgan and Amy do this but not Lee Weathers, who doesn't respond when Morgan presses her palm to the glass wall of her cell. [[spoiler:It's later revealed that Lee is a genetically-engineered synthetic human-like Morgan, but without her empathy as she was created as a corporate assassin.]]
* ''Film/NavySeals''. Lt. Curran is showing Claire Varrens a diving tank where the [=SEALs=] are training. On seeing the attractive journalist, Lt. Hawkins (who is in the tank) removes his breather and presses his lips to the glass.

-->"Remember, I can turn you off as fast as she can turn you on."
* Subverted in ''Film/TheTitan'' (2018). Rick Janssen is shown to his wife and son once he has been genetically transformed into ''Homo Titanien''. The process has rendered him mute, and he presses a transformed hand against the window of the lab, but they can only stare at Rick in horror and don't return the gesture.

* ''Anime/StarDriver'': It's a big trend for the boys to go outside of the class to the window and ask a girl to kiss them through the glass to show affection without being too serious. Several characters do this, and one girl, Kanako, loves doing this as way to show affection [[spoiler: without cheating on her husband.]]

* Happens between [[spoiler:Moka and Kurumu]] in season II of ''Manga/RosarioPlusVampire''. They are on opposite sides of a force field, and the latter has just been critically injured. They put their hands up against each others' from opposite sides of the force field before the latter collapses.

* In ''Film/TheCableGuy'', [[Creator/JimCarrey Chip]] tries to make Steven do it, but he refuses; Chip then does a parody of the similar scene from ''Film/MidnightExpress''.

* The 1992 French movie ''L'Amant'' (''Film/TheLover'', adapted from the eponymous novel by Marguerite Duras). The protagonist, a fifteen year-old French schoolgirl, is given a lift (with heavy UnresolvedSexualTension) to her school by a wealthy Chinese man who fell in LoveAtFirstSight with her. The next days she's [[StalkerWithACrush surprised to see his limousine parked outside the school]], so she walks up to the car and [[TheTease sensuously presses her lips to the window]] where he's sitting in the back seat.

:: However, it ends up being a SubvertedTrope. Lancelot comes to the window, they talk for a while, then he suggests that he think he's strong enough to drag the bars aside if Guinevere wants him to. She says yes, so he comes in and they have sex. [[SexInASharedRoom Kay the seneschal is still there, like she mentioned.]]

** In "[[Recap/DoctorWhoS35E3UnderTheLake Under the Lake]]", after a breach in an underwater base, sealed doors shut Doctor and Clara on opposite sides of a corridor. They engage in this trope via facing windows as the corridor fills with water.

The scene has Stiles pounding against the door ''screaming'' Scott's name, while Scott desperately tries to let him in. Eventually they both collapse to the ground and lie pressed against the door on either side, apparently just waiting to die together if they can do nothing else.

* The Bad Wolves' cover of "[[https://www.youtube.com/watch?v=9XaS93WMRQQ Zombie]]" by Music/TheCranberries was going to have Dolores O'Riordan sing with the band, but she died before the recording. The music video pays homage to Dolores by having an actress covered in gold paint (resembling Dolores in the Cranberries' original video) interact with Tommy Vext through a glass window. They start by placing their hands together, leaving a gold hand print.

* ''Theatre/AMidsummerNightsDream'': During the play within a play, the lovers Pyramus and Thisbe are separated for most of their lives by a wall between their houses. In the wall there's a chink, through which they talk and attempt to kiss.

** In "Under the Lake", after a breach in an underwater base, sealed doors shut Doctor and Clara on opposite sides of a corridor. They engage in this trope via facing windows as the corridor fills with water.

* ''Series/{{Austin and Ally}}'':

* In the previews for the ''Series/ICarly'' special titled ''iPsycho'' there's a scene where Sam forces Freddie to make out with a girl on the other side of a glass window. It's quite creepy.
