* AmericansHateTingle: The series did very poorly in France and French-speaking countries in general, no doubt due to the writers' repeated jokes at the expense of the country and its people [[note]] The most notable exception is Joan of Arc. While the show still pokes fun at her, she is portrayed in a much more positive light. [[/note]] and in particular the [[HistoricalVillainUpgrade negative portrayal]] of Napoleon Bonaparte.
* SugarWiki/AwesomeMusic: While not as well known as his songs from ''Animaniacs'' some of Randy Rogel’s songs from this show are pretty catchy including "A Tale That’s Told by the Bard" and "People Wanted Pepper on Their Food."
* CommonKnowledge: Contrary to popular belief, this series was not in fact produced by Creator/StevenSpielberg, despite it sharing many similarities with ''WesternAnimation/TinyToons'', ''WesternAnimation/{{Animaniacs}}'', and ''WesternAnimation/{{Freakazoid}}''. Tom Ruegger helmed this show on his own.
* CrossesTheLineTwice: "General Sherman's Campsite," a ''Series/PeeWeesPlayhouse'' parody set during the American Civil War, depicting General William Temeusch Sherman as Pee-Wee Herman and turning Pee-Wee into a PsychopathicManchild obsessed with setting fire to Atlanta, Georgia. A Website/YouTube comment stated this as "the worst thing [he] could have imagined..." before adding, "I love it."
* EnsembleDarkHorse:
** The Kid Chorus is this, thanks to their repeated presence in basically every single episode. Each of them has a very unique defining personality that's endeared them to fans and casual viewers alike. Charity Bazaar gets a special mention being possibly the most popular character, as well as being [[TheEeyore perpetually glum]] and sounding [[LittleMissSnarker hilariously monotonic]].
** Miss Information for the hosts, thanks to her [[TheDitz ditzy nature]] and, well, [[DumbBlonde spouting of misinformation]]. The fact that she can also entice people with [[HeadTurningBeauty her physical appearance]] (especially in her beach outfit) also helps.
* GermansLoveDavidHasselhoff: It's declared in the theme song that "they love [the show] in Bulgaria".
* HilariousInHindsight:
** Even though Billy West (who did voice work on this show) went on to play Richard Nixon on ''Futurama'' (a year or so after this show aired), he didn't voice Nixon on the sketch that centered on the Watergate scandal on the episode "20th Century Presidents." Creator/JeffBennett voiced Nixon.
** One of the sketches they had depicted Abraham Lincoln as Jerry Seinfeld complete with his own sitcom. Years later on ''Series/SaturdayNightLive'', one of their most popular sketches would be...a sitcom with Abraham Lincoln (only it would be based on the FX sitcom ''Series/{{Louie}}'', based on the life of comedian Creator/LouisCK).
* MemeticMutation: The [[https://www.youtube.com/watch?v=75F5RaU5wSM invasion]] song is one of the most popular segments from this show - thanks in part due to being ''very'' catchy.
* NightmareFuel:
** UsefulNotes/JosefStalin's song about what he loves can ''definitely'' be seen as this. One of the lyrics is even "Turning your dreams into scary nightmares".
** UsefulNotes/AdolfHitler appeared on the show [[OneSceneWonder all of once]]. Despite his over-the-top depiction as a BigRedDevil with the [[Creator/FrankWelker voice]] of [[WesternAnimation/InspectorGadget Doctor Claw]], he was portrayed [[VileVillainSaccharineShow deadly seriously with no humorous quirks to offset his villainy]], when, ironically, the {{Wartime Cartoon}}s [[Creator/WarnerBros from the same studio]] [[AdolfHitlarious depicted him as]] LaughablyEvil, as one would expect a show like ''Histeria!'' to do.
* RecycledAnimation: Histeria! was reportedly a very expensive show to produce, ultimately being $10 million over budget. Due to this, the show frequently recycled entire animation sequences for multiple episodes. Sometimes, these scenes would be re-timed to better fit newly recorded dialogue, resulting in the animation looking something disjointed. Other times, the animation would simply be reused as is, creating a very visible disconnect between the dialogue and lipsync. These instances are especially noticeable in the last few episodes, with the show's final episode being a glorified clip show.
* SuspiciouslySimilarSong: The verses of "The Invasion Song" are based on the [[RefugeInAudacity rather racy]] Music/TomLehrer song "I Got It From Agnes."
* SpiritualSuccessor: The show could be viewed as a DenserAndWackier version of ''WesternAnimation/IlEtaitUneFois l'homme''. The same could also be applied to the Peabody and Sherman segments of ''WesternAnimation/RockyAndBullwinkle'', the history songs on ''WesternAnimation/SchoolhouseRock'', and Creator/StanFreberg’s comedy album ''The United States Of America, Vol. 1''.
* ToyShip: Some fans of the show had ships for the kids, most notably Loud/Charity, Aka/Froggo & Cho Cho/Lucky Bob. Of course, these had [[ShippingGoggles no basis on the show]], as the kids were of the GirlsHaveCooties mindset.
* ValuesDissonance: The show's treatment of its characters of color is extremely stereotypical: Aka Pella is the only black person in the kid chorus and acts like a pre-pubescent version of a SassyBlackWoman; Cho Cho is an Asian caricature with an offensive name and has "Chopsticks" as her theme music; and Susanna Susquahanna is a Native American caricature, also with an offensive name. If the show were to be made today, these characters would be written out or retooled extensively to be respectful. Adding insult to injury, with the exception of Aka (voiced by Black Creator/CreeSummer), they are all voiced by Creator/TressMacNeille, who is white.
** Similarly, the [[FrenchJerk rather unpleasant stereotyping of French people]] is bad enough by American standards, but in French-speaking countries, the show has been blasted as a result. And the depiction of the Spanish Inquisition in the Convert or Die sketch is so bad that this show ''got in trouble with the Catholic League'', which accused them of teaching kids to ''reject Catholicism''!
* WhatDoYouMeanItsForKids: Despite being mainly oriented for kids, the show manages to sneak in some inappropriate jokes, violent and/or mature content (the latter being more understandable due to the history concepts covering a few gory areas) and a few profanities here and there.
