Tropes found in "Exercise Minute":
- Black Comedy: The entire segment is about how exercise won't do May The Mayfly any good, since her species is destined to live only a few minutes.
- Cold Open: The full title is "Cold Open: Exercise Minute".
- Comically Missing the Point: The Warners' oblivious reactions when May describes what's happening to her.
- Credits Gag: The Warners interrupt the Title Sequence to make the viewers get off the couch for a few minutes before watching the episode.
- The "Fun" in "Funeral": Defied Trope. The Warners look sincerely miserable at May's funeral.
- Irony: May's wings crumble from aging just as she's about to use them for the first time.
- Rapid Aging: Well, it's normal by a mayfly's standards, but May starts out young and withers away before our eyes in a matter of minutes.
- We Are as Mayflies: Played with, as a literal mayfly demonstrates the trope.
Tropes found in "Reichenbrain Falls":
- Convection, Schmonvection: Julia stands on the edge of a sizzling fondue pot, and when Brain actually falls in, the heat melts his spacesuit off. Neither of them suffer any injuries or even discomfort.
- Disguised in Drag: Two examples: Pinky as a female art teacher, and Julia as Pinky.
- EMP: Brain originally planned to create one that would black out all of Earth so he could, yes, Take Over the World in its aftermath. Julia then comes up with a scheme to trick Brain so she can use the EMP to rule the world instead.
- Evil Laugh: Julia does a few of these once she's discovered.
- Evil Versus Evil: Played for Laughs, but Brain and Julia battle each other over which of them will rule the world. They both lose.
- Face–Heel Turn: Julia was originally a Nice Girl, but by the time of this episode she's become a vengeful Arch-Enemy to Brain.
- Flashback: Used to show Pinky and Brain posing as middle school teachers to get the students to build Brain's rocket for free, and how Julia also infiltrated the school to kidnap Pinky.
- Gambit Pileup: When Brain and Julia fight over which of them will get to control the Earth, they wind up ruining each other's schemes.
- Latex Perfection: Julia's mask of Pinky is perfect despite being made out of papier-mâché.
- Literary Allusion Title: It's a reference to the Sherlock Holmes story "The Adventure of the Final Problem", in which Reichenbach Falls
is where Holmes confronts Professor Moriarty. - Master of Disguise: Julia poses as Pinky and almost pulls it off. She also becomes a Mobile-Suit Human to capture Pinky in the first place.
- Mood-Swinger: Julia's continuing mental damage causes her to alternate between Tranquil Fury and just plain fury.
- Mr. Exposition: The students lampshade Brain being this in the flashback.
- Out-of-Character Alert: "Pinky" acts slightly off throughout the episode. He calls Brain "babe"; he guesses that Brain's code might be significant mathematical constants like pi and e; he correctly notes that there are 100,000 possible five-digit combinations, then goes slightly nuts while considering that fact; he says "Gort!" instead of "Zort!" (and then corrects himself); and his response to Are You Pondering What I'm Pondering? isn't quite as nonsensical as usual. These are all hints that he's actually Julia in disguise, which Brain eventually figures out.
- Paste Eater: Pinky eats paste multiple times in the episode, which helps him escape from Julia's glue trap.
- Pungeon Master: Julia makes bad puns while threatening Brain, requiring her to backtrack for a better one. He soon starts following her example.
- Recursive Crossdressing: Julia briefly disguises herself as Pinky disguised as a female art teacher.
- Sequel Episode: To "Mousechurian Candidate" since it involves the return of Julia.
- "Shaggy Dog" Story: It turns out that the rocket the students built was malfunctional, meaning Julia couldn't have reached the ISS even if she had the codes.
- Shout-Out:
- The school's name is Malcolm in the Middle School.
- Instead of "Zort!", fake Pinky shouts out "Gort!"
- The reason why Julia sometimes gets into fights on Goodreads:Julia: The only part of Ulysses worth reading is the last chapter, and everybody knows it!
- Spy Catsuit: What Julia is wearing beneath her Pinky disguise.
- Suddenly Obvious Fakery: The "space station" where Brain wakes up is later revealed to be a poorly-made replica inside a cardboard box on the school's auditorium stage, with Brain suspended from a string to simulate weightlessness (even though we clearly see other objects floating around the room before the reveal).
- Take That!: After realizing he's in space, Brain says "Please don't tell me Elon's here too."
- Took a Level in Badass: Julia has become a competent fighter since we last saw her.
- Villain Respect: Julia gives Brain this after allowing him to come up with a better one-liner.
- We Will Meet Again: Julia ends the episode by hijacking Brain's rocket (and then a hawk after the rocket malfunctions) and vowing to return.
- With Great Power Comes Great Insanity: Julia is now able to match wits with Brain, but suffers some Sanity Slippage thanks to his initial attempt to brainwash her last season.
- You Wake Up in a Room: In this case, Brain wakes up aboard the International Space Station (or so he thinks) with no memory of how or why he came to be there.
Tropes found in "Targeted Ads":
- Bland-Name Product: The Tuna Fresh Gum commercial is a parody of Doublemint Gum commercials.
- The Cameo: Mr. Director appears on a driver's license at the end of the DMV Fantasy Camp ad.
- Cultural Translation: The Brazilian dub replaces the DMV with its Brazilian counterpart, DETRAN.
- Department of Major Vexation: One of the ads is of a DMV Fantasy Camp where the campers are as obstructive and unhelpful as DMV bureaucrats are usually portrayed in fiction. The ad ends with a note that the people who were supposed to take calls from potential campers aren't available because they're stuck at the actual DMV.
- Failure Is the Only Option: None of the ads have anything to do with the prompts received from the audience.
- Rattling Off Legal: The Tarantula Whistle has a long disclaimer about how the company that makes it isn't responsible for your or your loved one's deaths, and is also part of The Illuminati.
- Spiders Are Scary: Zig-Zagged Trope. The ad for the Tarantula Whistle tries to convince viewers that they can use the product to turn tarantulas into a cross between obedient pets and their own personal army. Actually, it's quite the opposite.
Tropes found in "Starbox and Cindy":
- Barefoot Loon: Cindy is as much of a Cloud Cuckoolander as ever and goes barefoot throughout the episode. Justified Trope because she's playing around in the bathroom.
- Not What It Looks Like: When Starbox's leader contacts him to see why he hasn't given the invasion signal, the first thing he sees is a closeup of his subordinate's bare butt since Cindy has stripped him naked to bathe him. The leader assumes it's an inconvenient time and hangs up.
- Talkative Loon: As always, Cindy is a Motor Mouth who's in her own little world.
