History SeriousBusiness / WesternAnimation

** In the episode "Catch 'Em If You Can", during a WeNeedADistraction moment.
--->'''Airport Worker:''' I'm sorry we're not supposed to give out passenger's itineraries.\\
'''Bart:''' I understand. Hey what's that crazy girl doing?\\

** Everyone slowly becomes addicted to a jigsaw/card game thing called "Ajimbo", becoming like zombies that forget how to play other games like kickball. [[SubvertedTrope Subverted]] (kinda) with the implication the puzzle is an addictive ArtifactOfDoom.

** [[WesternAnimation/PhineasAndFerb It's not just golf in miniature!]]

* ''WesternAnimation/CodenameKidsNextDoor'': The Kids Next Door once encountered Rupert Puttinsky, a guy who made "miniature golf" Serious Business... to the point of [[InsistentTerminology insisting on calling it as such]]:
-->'''Numbuh 5:''' They have champs in mini golf?\\
'''Rupert:''' The game is called ''miniature golf''!
** And don't you ''dare'' call miniature golf a stupid game, either.

** For the titular organization, many kid activities are Serious Business and often threatened by adults. Case in point: the ban on ''drinking [[FrothyMugsOfWater (root)]] beer'' in "Operation Pop", a prohibition parody.
** Also ice cream, in which the search for the true nature of the "fourth flavor" (vanilla, strawberry, and chocolate being the core three) is akin to that of a religious quest. Ice cream was so serious business to one character that he became an ''OmnicidalManiac'' over everyone eating his ice cream and not thanking him for it.
** Numbuh 3 shows tendencies of this when it comes to Rainbow Monkeys.
** The entire show rests on the premise that childhood is Serious Business. Which is also TruthInTelevision.

** A clear sign of this trope is whenever Eric Cartman belts out his infamous "[[LittleNo No!]] [[BigNo Noooooooooooooooo!]]" {{catchphrase}}.

** In "The List, Stan just asks Wendy why Kyle was placed last on the girls' list of cutest-to-ugliest boys, but Wendy quickly uncovers a [[MilkmanConspiracy conspiracy]]; the high-ranking members of the girls' Pleases and Sparkles Club (Bebe, Jenny, Lola, and Red) forged the list in order to put Clyde at spot #1, boost his confidence and poularity, be able to date him, and [[GoldDigger convince him to give them]] [[AllWomenLoveShoes free shoes from his father's store]]. Apparently there is a very complex process as to how the members of the Pleases and Sparkles Club create a list, and tampering with one is considered a serious violation (Bebe outright says that Kyle ending last on the list was simply just a coincidence produced by the tampering). Wendy calls the police on Bebe for abusing her authority, and the police ''are willing to arrest her for forging the list''. Bebe on her part tries to kill Wendy so she doesn't expose the real list to the public.
** PlayedForLaughs in "The Death of Eric Cartman", when the boys finally decide to disown Cartman and give him the SilentTreatment. While this was arguably a long time coming given all the atrocities Cartman has committed upon them, but it was ''eating the skin off of their KFC'' that was the last straw.

--->'''Cheater:'''[nervously] Aw. c'mon! ''Everybody'' does it!

* Little League Baseball to Springfield in the Boys of Bummer: when they were winning the kids were allowed to throw eggs at people's faces (and they gladly took it), Bart mooned the audience and asked them to worship each cheek, and when Bart cost the game the dollar apparently weakens and townspeople push him to suicide.

* ''WesternAnimation/HeyArnold'': In "Curly Snaps", Curly is obsessed over being the "ball monitor" (the kid whose job is to hand out and collect all the kickballs before and after reccess) for a week. Every other kid hates the job and considers it a mediocre and boring chore while Curly believes it to be an admirable and highly respected position. He ends up going crazy and locking himself in the principal's office with all the balls and chucks them at people after Mr. Simmons accidentally skips his turn. Sid, who was given the job instead, flat out tells Curly he doesn't want the job and he can have it.
