History YMMV / TheAdventuresOfJimmyNeutronBoyGenius

* EthnicScrappy: Elke, Carl's Swedish pen pal in "Carl Wheezer: Boy Genius". She's a dumb blonde, has a silly accent, speaks broken English, and doesn't seem to care that Carl nearly got her and everyone else killed. Thankfully, she only shows up in one episode.

* EvilIsSexy: Invoked and parodied with Beautiful Gorgeous.

** Dr. Sidney Moist. He was incredibly crazy and hammy, but only had one episode in Season 3 (and a cameo in the third ''Jimmy/Timmy Power Hour''). It would've been hilarious to see more of him for sure.

* DesignatedHero: Jimmy, while being well-meaning and not genuinely trying to hurt people with his inventions, unintentionally comes across as this. His inventions almost always directly or indirectly cause the problem for the episode that he then has to fix, and more than once he's created or brought a villain over who endangered the entire town. His InsufferableGenius behavior (such as insisting on calling salt by its chemical compound name just to sound smart in one episode) and tendency to show off his intellect to people (which is heavily implied to be the reason why Cindy picks on him) is to the point where even his own family (other than his parents) can't stand to be around him. Speaking of his parents, they genuinely love and want to spend time with their son, but Jimmy spends almost all of his time in his secret lab or going off on dangerous adventures against their wishes, and doesn't even think of inventing anything to make his mom's life easier around the house. It's no wonder why Jimmy has made so many more enemies than friends.
%% ** Jimmy is a JerkWithAHeartOfGold at worst, but he does cause many of the problems he has to fix. Cindy herself lampshades it. In fact, his arrogance, [[DitzyGenius ditziness]], and the problems he caused throughout the series are one of the reasons why he has made ''so many enemies'' instead of friends.
%% ** Jimmy’s friends tend to be like this whenever they abuse Jimmy’s inventions, cause the problem of the week, and blame him for it.
%% * DesignatedVillain: Cindy has a tendency to be subject to this trope more often than other characters:
%% ** In "Best in Show" Cindy has Goddard disqualified from a pet contest on a very solid basis of him not being a real dog and thus not eligible for participation according to the rules which is enough to brand her the asshole of the week. And while that doesn't excuse her not being able to spit out a thank you to either Jimmy or Goddard [[spoiler: when the latter saves her life at the end]], if Jimmy didn't use the opportunity to [[TheReasonYouSuckSpeech rub it in her face how wrong and immoral she was and how much better a person he is]], she most likely would have apologized.

** A soundalike of the MissionImpossible theme can be heard in "Win, Lose, and Kaboom" when Jimmy and friends infiltrate the military base to retrieve the fallen space rock. This same music can also be heard in "The Incredible Shrinking Town."

** Also, in "Win, Lose, and Kaboom!", there's Jimmy's line to Sheen after he stupidly reveals about the space rock to the government:

** Despite [[WesternAnimation/PlanetSheen his infamous spin-off]], Sheen ''does'' still have some fans who find him funny (in the movie and the original show, anyway), helps that said spin-off was quietly cancelled after quickly losing its relevance.

* HilariousInHindsight:
** One of the shorts is called ''WesternAnimation/CarlSquared''.
** The episode "Sleepless in Retroville" becomes a whole lot funnier after watching WebAnimation/JimmyNeutronHappyFamilyHappyHour, since both involve [[spoiler:aggressive pizza]].
*** The idea of an evil floating pizza face feels somewhat prescient to ''VideoGame/PizzaTower'' as well, which features one as its main antagonistic force.
** The LiteralSplitPersonality characters from an episode bear strong resemblance to the Sextuplets from ''Anime/OsomatsuSan''.
** In "Normal Boy", Cindy wishes that Jimmy would just go to college and leave her and the other students alone. Jimmy would later do just that in "Jimmy Goes to College."
** Sheen pretending to be Tee's conscience in "The Incredible Shrinking Town" is funny in light of "League of Villains" (where Sheen is responsible for Tee's HeelFaceTurn).
** The evil clone from "Send In The Clones" resembles a certain [[WebAnimation/EddsWorld red-hoodie wearing Norwegian.]]
** Pitz (the guy sporting a bowl cut and a bowtie) bears a striking resemblance to [[Manga/JojosBizarreAdventureJojolion Joshu Higashikata.]]
** Scientifically engineered killer pants that were originally programmed to be self-maintained? [[Film/{{Slaxx}} A horror/comedy film released almost 20 years later]] revolves around that very concept.
** [[Franchise/MyHeroAcademia This wouldn't be the last time]] an organization titled "The League of Villains" would serve as an overarching big bad.

%% * DesignatedHero:

* FountainOfMemes: Hugh Neutron, Carl, and moreso Bolbi have an internet following based on this.
** Sheen and Skeet are also this, to a lesser extent.

* StrawmanHasAPoint: Skeet in "Men at Work" might not be the smartest character on the show, but many viewers are quick to point out that two of his reasons for demoting Jimmy in the first part of the episode are fairly understandable:
** First, he demotes Jimmy from cashier to mop duty because the latter wasn't "pressing the buttons" on the cash register. This is meant to show that he can't understand that Jimmy's smart enough to have already memorized the prices ''and'' be able to calculate the tax and change in his head. However, while cash registers are used to keep track of prices and tax, they're also used to provide a physical record of financial transactions (for both budget and inventory purposes), as well as the ability to provide customers with a receipt. Plus, employees stealing an extra dollar from the register every so often isn't unheard of in the fast-food industry, and if there's no record of transactions at all...
** Later on, he demoted Jimmy down to simply advertising the store out front because he called salt "sodium chloride". While this is meant to show Skeet as too stupid to understand that "sodium chloride" and "salt" mean the same thing (as evidenced by his reasoning for demoting Jimmy being that the latter ''doesn't'' know what salt is), most people don't refer to salt as Sodium Chloride in a non-chemistry context. In fact, those who do refer to it by its scientific name in normal conversation tend to come off as a pretentious jackass -- like Jimmy does.

* UnintentionallyUnsympathetic: Jimmy at the beginning of "Men At Work". While working at the register, instead of ringing up the customers' orders on the cash register, he memorizes the prices and does the taxes and change in his head. His manager Skeet chastises him for this, telling him to use the register which Jimmy brushes off and then suggests changing [=McSpanky's=] slogan and putting scientific words into it when Skeet points out he didn't say "Big [=McThankys=] from [=McSpanky's=]" to the customer. And then when Skeet demotes Jimmy to mop duty afterwards, he's asked to mop up the restaurant floor. When Skeet tells him he missed a spot of spilled salt, he insists on correcting him and calling it by its chemical name: [[InsistentTerminology "sodium-chloride"]], which causes Skeet to demote Jimmy again for thinking that he doesn't know what salt is. At the beginning, You're supposed to feel sorry for Jimmy because his super-genius mind is being unappreciated and Skeet is picking on him, but in reality what he was doing was a textbook example of InsufferableGenius behavior, particularly using scientific words in a simple fast food joint while talking back to his employer for trivial reasons. And in terms of his work at the register, what Jimmy was doing was illegal under-the-table transactions for a business that needs all transactions monitored by the register for the sake of inventory and taxes. His method is also unable to provide a sales receipt to the customers.

** Skeet. According to the show, he's a [[TheDitz dim-witted]] cashier who [[KnowNothingKnowItAll acts like he's a lot smarter than he is]]. According to fans and memes, he's a [[SmarterThanYouLook well-spoken genius]] who's able to psychologically analyze and [[TheReasonYouSuckSpeech rip apart]] Jimmy's obssession with being smart.
