* 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.
* AdoredByTheNetwork: It was this to Creator/KidsWB when it [[ChannelHop channel-hopped]].
** TheHub adored this show more than Creator/KidsWB 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.
* {{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.
* TheDanza: Colin, the kid who talks about Randy Beaman, was voiced by Colin Wells.
* 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: JeffBennett filled in for John Mariano on the very few occasions Bobby sang. [[note]]With the exception of the very brief [[WestSideStory "Coo"]] segment.[[/note]]
* TheOtherDarrin: Walter Wolf was voiced by FrankWelker in "Hurray for Slappy" and Creator/JessHarnell in all subsequent appearances.
* RealLifeRelative: Tom Reugger's son Nathan Reugger voiced Skippy.
* 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 Rob Paulsen, who voiced Yakko, Dr. Scratchansniff, and Pinky.
* 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. 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 American Gladiators 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.
** 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''). One wonders what character he would have voiced if he was hired on the show.
** 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.
* WriteWhoYouKnow: Nicholas Hollander based Katie Kaboom on his teenage daughter.
