* ActorAllusion: The short "Sir Yaksalot" has a segment that parodies ''Franchise/{{Godzilla}}'' movies and Kaiju films in general, where the Warner siblings attempt to get help against the dragon from a council used to dealing with giant monsters, complete with their voices being (poorly) overdubbed. PerryMason is among them, referencing Raymond Burr's role in the localized versions of some of the Godzilla movies.
* ActuallyPrettyFunny: "Super Strong Warner Siblings" was a deliberate TakeThat against ''Series/MightyMorphinPowerRangers'' as the producers were not happy about ''Animaniacs'' playing second fiddle to Power Rangers (this was done after the channel hop to Creator/KidsWB). Power Ranger fans actually found the parody hilarious then and even now.
* AdoredByTheNetwork: It was this to Creator/KidsWB when it [[ChannelHop channel-hopped]].
** TheHub adored this show more than Creator/KidsWB, Nickelodeon, and FOX ever did. They aired promos for it during every program on the channel including ''Animaniacs'' itself, and had constant marathons of the show whenever a holiday was near (Christmas, Martin Luther King Day, Super Bowl Sunday, and even President's Day). Not only that, the show at one point aired for three hours on weekdays. They even got Rob Paulsen, Jess Harnell and Tress [=MacNeille=] to record new spots, in character as Yakko, Wakko and Dot respectively, for the show's reruns. Due to this, it gained a new generation of child fans, and parents who watched the channel say that their kids loved it even more than ''WesternAnimation/MyLittlePonyFriendshipIsMagic''. Unfortunately, after the channel became Creator/DiscoveryFamily, [[ScrewedByTheNetwork the series was one of the few that was completely removed from the channel]].
** [=GO!=], an Australian family network similar to The Hub, aired this show twice in the morning, noon, and night when they had the rights. It even axed ''WesternAnimation/BenTen'', ''WesternAnimation/TomAndJerryTales'', and the VideoGame/{{Tamagotchi}} anime's English dub just so they could show more ''Animaniacs''.
* ChannelHop: From Creator/FOXKids to Creator/KidsWB when it was first-run. It has also aired on Nickelodeon and [[Creator/DiscoveryFamily The Hub]].
* {{Composers}}: Unlike ''WesternAnimation/TinyToonAdventures'', ''Animaniacs'' used a comparatively small but stable group of composers: Richard Stone, Carl Johnson, Steve and Julie Bernstein, Gordon Goodwin, Tim Kelly, and J. Eric Schmidt.
* CrossdressingVoices: While the series mostly subverts this with young male characters, being voiced by either [[DawsonCasting adult males]] or [[ChildrenVoicingChildren actual boys]], most dubs play this straight. But one of the more interesting cases is that unlike most versions, Wakko in the Latin American dub is voiced by actress Giset Blanco.
* CulturalTranslation: The German dub changes from Hello Nurse playing Chopin without rehearsing, to playing Brahms, to fit the rhythm of the song about her better.
* CutSong: Randy Rogel wrote a song for the show entitled "The Geologic Clock," in which Yakko sings about the history of the Earth, that ultimately went unused.
* TheDanza: Colin, the kid who talks about Randy Beaman, was voiced by Colin Wells.
* DubNameChange: The German dub changes Professor [[OverlyLongName Otto von Shnitzelpusskrankengescheitmeyer's]] name to Aloysius Bierpichlersemmelknödelmeier.
* EditedForSyndication: When ''Animaniacs'' aired on {{Nicktoons}} Network and Nickelodeon, the opening theme was so plastered with references to the channel (through use of redubbing and digital editing) that fans rejoiced when the [=DVD=]s of the original episodes were released.
** Averted with Creator/CartoonNetwork and The Hub, as both channels air the episodes exactly as they used to air on FOX and the WB and on the DVD sets.
* EnforcedMethodActing: Whenever Nathan Ruegger (Skippy) had to laugh as part of the script but couldn't laugh convincingly enough, his dad would come into the studio to tickle him.
* FakeBrit: Wakko and Pinky both have British accents provided by American voice actors, but other than their accents, there's really nothing to indicate that they are British.
* MissingEpisode: Episode #55 has a chase scene bumper that's missing from the [=DVDs=] as well as reruns on TheHub. It is, however, on digital releases.
* MilestoneCelebration: Spoofed by the "65th Anniversary Spectacular!" Fridge Brilliance kicks in when you realize 1) airing in the mid-90s, it roughly corresponds to when the BackStory claims the Warners were created; 2) it ''is'' a 65th - the 65th ''episode''; and 3) it's an actual milestone, as the first season finale.
** For the show's 20th anniversary, a fourth DVD set will finally be released containing the remaining episodes.
* NamesTheSame: Kiki the Gorilla, and Pesto's girlfriend Kiki.
* NonSingingVoice: Creator/JeffBennett filled in for John Mariano on the very few occasions Bobby sang. [[note]]With the exception of the very brief [[Theatre/WestSideStory "Coo"]] segment.[[/note]]
* TheOtherDarrin: Walter Wolf was voiced by Creator/FrankWelker in "Hurray for Slappy" and Creator/JessHarnell in all subsequent appearances.
* OutOfOrder: The exact production order isn't clear, but the first season -- which accounts for the majority of the series' run -- was clearly aired out of order because some characters' introductory episodes, like Minerva Mink and Katie Ka-Boom, clearly aren't their actual first appearances. The DVD releases retained this error, leading to "Meet Minerva" not showing up until the third volume out of four.
* RealLifeRelative: Tom Reugger's son Nathan Reugger voiced Skippy.
* RecycledScript: The episode "Wakko at the Bat" is basically a rehashing of the ''WesternAnimation/TinyToonAdventures'' short "Buster at the Bat" in that it's a retelling of the poem ''Casey at the Bat'' that ends with a happy ending after a fake-out of following the original poem's DownerEnding. Ironically, the same episode featured a parody of Disney's ''Disney/{{Pocahontas}}'' called ''Jokahontas'', which featured a musical number accusing Disney of recycling the same old stories in every movie they made that featured a female protagonist.
* ScrewedByTheNetwork: Jamie Kellner (whom you may know as the guy who claimed watching television while skipping ads with a [=DVR=] is tantamount to stealing, as well as the guy responsible for cancelling all programming from Wrestling/{{WCW}}, leading to the company's bankruptcy in 2001) apparently ignored the very high ratings from older audiences while the show was on WB and found the low ratings from kids to be an excuse to cancel the show, though it shouldn't be a surprise as a lot of cartoons created by Warner Brothers at the time were canceled for similar reasons, like ''Freakazoid!'' and ''Road Rovers''.
** [[http://www.animenewsnetwork.com/interest/2016-04-13/animaniacs-freakazoid-producer-credits-pokemon-for-wb-cartoon-decline/.101008 Series creator Tom Ruegger later confirmed]] that Animaniacs and several other Warner Bros. cartoons saw their cancellations in the 90s due to their higher production costs in comparison to then ratings sensation ''Anime/{{Pokemon}}'', which was licensed to Kids WB on a discount.
* TalkingToHimself:
** Notably Creator/RobPaulsen, who voiced Yakko, Dr. Scratchansniff, and Pinky.
** The director and Mr. Klump from "The Sunshine Squirrels" were both voiced by Creator/CoreyBurton, and were the only two of the three characters Corey Burton played in that short to interact with one another.
* TropeNamer:
** HelloNurse
* UnintentionalPeriodPiece: Less so than other '90s shows, but the 1994 episode "Baloney & Kids" includes ''two'' separate references to the Nancy Kerrigan/Tonya Harding altercation from earlier that year [[note]]Though Kerrigan's stint on ''Series/DancingWithTheStars'' gave her some renewed notability recently[[/note]]. Moreso for the Kids' WB episodes, due to it being much heavier on the 90's pop culture references then the earlier episodes. Jokes referencing movies, TV Shows, and songs at the time such as ''Film/{{Speed}}'', ''Film/{{Fargo}},'' ''Series/{{Friends}}'', and the [[OneHitWonder Maca]][[DanceSensation rena]] didn't exactly aged well. The episode parodying ''Series/AmericanGladiators'' was particularly bad about this, due to airing only a few months before the actual show was cancelled. The ''Disney/BeautyAndTheBeast'' parody was another noteworthy example, airing five years after the movie had come out.
* WhatCouldHaveBeen:
** The concept for the show was originally going to star a family/group of green ducks, since the baby version of Plucky Duck from ''WesternAnimation/TinyToonAdventures'' went over so well, but wouldn't be related to Plucky and would have nothing to do with the rest of that cast. The team eventually decided that ducks [[ItsBeenDone "have been done"]] and retooled the premise to star 1930s-style cartoon characters.
** In the phase where the Animaniacs were going to be ducks, they consisted of three brothers - Yakky (the chatty character), Smakky (an ill-tempered character with a predilection for violence), and Wakky (the odd and energetic character). As the design evolved away from ducks, a sister (who was not named in concept art) was added to the ensemble. Yakky shared Yakko's body design, but was dressed only in a blue bow-tie, Smakky had Wacko's body and clothes (albeit with a green shirt instead of a blue one), but a sported a scowl and perpetually had his arms crossed, Wakky was a small, Dot-sized character who wore blue shorts, and Dot's design at this point included a pink blouse and a pink bow in her hair. Yakky would eventually become Yakko, with the only major change being swapping out the bow tie for a pair of brown slacks. Wakko was born from merging Wakky's personality and Smakky's character design, while Smakky was ultimately dropped as a character. Dot more or less went unchanged aside from abandoning her blouse and swapping out the bow for a flower.
** Pip was originally supposed to be a dog.
** Creator/CharlieAdler auditioned to do voicework on this show (and his rejection is why he quit ''WesternAnimation/TinyToonAdventures'').
** There were some ideas for sketches that were never used, but are cool thou.
*** One wonders what character he would have voiced if he was hired on the show.
*** A sketch idea about a gecko was not used but the concept later became The Iconic (Gieco Gecko).
** Creator/PatrickStewart was considered to voice The Brain.
** Slappy Squirrel was originally an older version of Screwy Squirrel, but the creators couldn't get the rights. Sherri Stoner liked the idea of an aged cartoon character because an aged cartoon star would know the secrets of other cartoons and "have the dirt on [them]".
** One unused idea for the series was a soap opera parody about amoebas called As the Petri Dish Turns.
** "Yakko's Universe" was initially written with a verse describing the planets in the solar system and ending with the lyric, "It's a small world after all." This was changed not only because a song about the planets was already being conceived for the show, but they knew the Disney reference would not fly.
* WriteWhatYouKnow: It's been said that the episode "Bumbie's Mom" was based on Sherri Stoner's own trauma at seeing the death of Disney/{{Bambi}}'s mother when she was a child.
* WriteWhoYouKnow: Nicholas Hollander based Katie Kaboom on his teenage daughter.
