History HeyArnold / TropesQToZ

* In ''WesternAnimation/TheAdventuresOfJimmyNeutronBoyGenius'', Hugh claims he paid a scalper one hundred bucks for tickets to Jimmy's ''free'' school talent show.

* SuspiciouslySpecificDenial: Phoebe gives one in "Phoebe Breaks A Leg" when Arnold discovers she was faking a broken leg that pretty quickly turns into a MotiveRant partway through.

* SmallParentHugeChild: [[HugeSchoolgirl Huge Schoolgirl]] Patty is much bigger than her parents, who both have dwarfism.

* YouHaveToHaveJews: The Jewish faith and Jewish culture are very well represented among the cast. Harold and his parents are Jewish, as is Mr. Green the butcher (and later city councilman). Many other characters aren't explicitly Jewish but are implied to be (or at least have a strong affinity for the culture) at different times: Eugene's last name is Horowitz, Sheena can read Hebrew, Helga frequently uses Yiddish insults, and Gerald recites a Hebrew prayer in TheMovie.

* ThoseTwoBadGuys: Several episodes feature a pair of crooks named Vic and Morrie.

** "Das Subway" is taken almost beat-for-beat from ''Theatre/TheOddCouple'' episode, "The Subway Show."

* SpotlightStealingSquad: Helga. She received more [[ADayInTheLimelight day in the limelight]] episodes than any other supporting character (even Gerald, who's supposed to be Arnold's best friend), and was the most developed character on the show. By seasons 4 and 5, she more or less became the series' true protagonist. It even extends to this very wiki. Her list of tropes on the Characters page [[TropeOverdosed was so long]] (it took up at least a quarter of the page and was twice the length of Arnold's) it was split off into a page of its own (Arnold eventually got one as well). Administrivia/TropesAreNotBad, since she's arguably the series' most popular character.

* SickEpisode: Helga thinks she's sick with Monkeynucleousis in "Monkey Business" and will die soon, but it turns out she's only being paranoid. She's also CompletelyMissingThePoint, as she read about the disease she thinks she has in a book called ''Diseases Long Since Debunked By Modern Science''.

-->'''Eugene''': Come one. You're a wimp.

* RealityEnsues:
** Arnold fixing Eugene's bike. Although the bike comes out looking like new, Arnold is still a nine-year old boy. Soon after Eugene leaves, Abner comes by with the brake cable in his mouth. Eugene rides down a hill unable to stop, made worse when he rips the handlebars off trying to steer. Eugene crashes and is sent to the hospital.
** When Arnold and Gerald go to a baseball game, they only have enough money for the tickets, until they buy some tickets half-price from a scalper. They buy the cheap tickets, overload on merchandise... and when they get to their seats, [[TheWorstSeatInTheHouse they're an obstructed view, and in the worst part of the park]].
** In "Timberly Loves Arnold", Arnold fears that rejecting Timberly will hurt her feelings. When he finally does, Timberly just goes off into a tangent about waffles, goes inside for a snack and off-handly tells Arnold that he doesn't have to be her "boyfriend" if he doesn't want to be. She may have been super insistent on her infatuation, but it was still just that: infatuation. From a first-grader. It didn't matter ''that'' much to her.
** In "Principal Simmons", Mr. Simmons is given the chance to run the school as principal and imagines it as an idyllic, academic paradise for children thanks to his lenient rule and lack of restrictions. Instead it becomes a chaotic urban jungle since it turns out that some sort of order and rule are required to effectively run a school full of pre-teens.
** In "Curly Snaps", Curly has been looking forward for weeks to be the new ball monitor, and snaps when he finds out that Sid has been chosen instead of him. He takes all the dodgeballs and takes over Principal Wartz's office, refusing to come out unless his demands are met, and pelting anyone who tries to stop him with dodgeballs. At the end of the episode, Mr. Simmons finds out that Curly was the true ball monitor after all, and Curly agrees to let Sid be the ball monitor for the rest of the week. However, Principal Wartz still gives Curly detention for his reprehensible behavior.

** "Das Subway" is taken almost beat-for-beat from ''Theater/TheOddCouple'' episode, "The Subway Show."

** In "New Bully on the Block", bully 5th grader Music/{{Wolfgang|AmadeusMozart}} is joined by a new 5th grader bully named Music/{{Ludwig|VanBeethoven}}.

* ThemeNaming: Helga and her sister have the same name: "Olga" is the Slavic version of the Germanic "Helga".

** For a split-second, Abner is seen using a litter box in "Helga's Locket" before Helga lands on him [[{{Squick}} AND the litter box]], implying that he is not fully housebroken. TruthInTelevision, as real life pigs actually use litter boxes when being potty-trained.

** For a split-second, Abner is seen using a litter box in "Helga's Locket" before Helga lands on him [[Squick AND the litter box]], implying that he is not fully housebroken. TruthInTelevision, as real life pigs use litter boxes when being potty-trained.

* ThatPoorCat: Practically once per episode, there will be the sound of a cat yowling off-screen.

* YourCheatingHeart: In "Arnold Visits Arnie", Lulu (Lila's darker counterpart in Arnold's subconscious) flirts with Arnold and harasses him despite being rejected by him several times since she's Arnie's girlfriend.

* TokenMinorityCouple: Some episodes had Gerald, Arnold's BlackBestFriend, paired with Phoebe, Helga's half-Japanese best friend. Then again, it could be said that it ''is'' a multiracial pairing so it could be something of a subversion. Given the rest of their classmates they were probably better off.
