''Bill & Ted's Excellent Adventures'' is an AnimatedAdaptation of the ''Film/BillAndTed'' movies that aired as a SaturdayMorningCartoon on Creator/{{CBS}} and Creator/{{Fox}} for two seasons, from 1990 through 1991.

A ShortRunner Live Action adaptation was also produced with the same name and aired on Fox in 1992.

!!Provides examples of:
* AffectionateParody: Of {{Series/Mister Rogers|Neighborhood}}. In the second season, those two righteous dudes were shocked and totally bummed out to learn that their favourite childhood show, [[WritingAroundTrademarks Mr. Radish's Condo]], is about to be cancelled because [[GoodIsOldfashioned kids today don't want his brand of sweetness]]. Cue Wyld Stallyns trying to make him stay... [[UnwantedAssistance and making things a lot worse for him]]. Eventually, Mr. Radish decides to [[WereStillRelevantDammit change his image completely]], ending up as a TotallyRadical rocker, which Bill and Ted initially consider to be most excellent... until they realise [[WhatHaveIDone that maybe this was perhaps a most]] {{JustForFun/egregious}} error in judgement. Thankfully, [[DeusExMachina Rufus shows up]] with Ted's bratty brother, who points out to Mr. Radish that you should BeYourself, [[SomeAnvilsNeedToBeDropped for your own sake if nothing else]]. Mr. Radish agrees, and changes back into his [[CostumeInertia red sweater]]. It came after an episode that parodied ''Series/LeaveItToBeaver''.
%%* AnimatedAdaptation
* ArtEvolution: The show changed styles greatly after switching from Creator/HannaBarbera to Creator/DiCEntertainment between the ChannelHop. This is evident with Ted's design, as he goes from dot eyes during the first season, to a more standard "Black pupils on white sclerae" look in the second.
** The animation itself was also more prone to be more [[LimitedAnimation choppier]] and [[OffModel error prone]] during season 2.
* CelebrityParadox: In the below-mentioned record store scene, Rufus notices a Creator/GeorgeCarlin comedy album on a shelf and shoots an AsideGlance to the audience.
* ConspicuousCGI: Most of the shots of the time machine in the Season 1 opening are rendered as such.
* EitherOrTitle: Season 1 episode "The Birth of Rock And Roll, or: Too Hip For The Womb." The episode featured rock legend Little Richard in an InkSuitActor role. He even furnished his voice for the episode.
* MilhollandRelationshipMoment: The titular heroes once broke a vase and went through great lengths to replace it before Bill's parents (father and stepmother to be precise) found out. They did get a replacement vase but ended up breaking it and Bill's stepmother showed up soon after. She then told the boys the vase was just some free prize they got at some restaurant. (Basically how the boys got the replacement vase in the first place).
* OpeningNarration: From the Hanna-Barbera version:
-->'''Rufus:''' I had been selected for a most important journey. I was to help fulfill the destiny of the two Great Ones...Bill and Ted.[[note]]"Wyld Stallyns rule!"[[/note]]
* RefugeeFromTVLand: There's an episode where the booth is used to retrieve a character from a TV show parodying ''Series/LeaveItToBeaver''. As a result, the show never ends and nothing else can ever be shown on TV, so they have to put them back.
* {{Retool}}: Its second season saw a ChannelHop from CBS to Fox and a transformation into more of a tie-in for Fox's live-action series of the same name, with the original voice actors (Winters, Reeves and Carlin) replaced by TheOtherDarrin actors from the live-action series. The phone booth underwent a change to use "Squint" technology that allows Bill and Ted to go into books, TV shows and even the human body. It's even been shown to go into movies and [[RecycledINSPACE IN SPACE]], although this is only in the new intro.
%%* SaturdayMorningCartoon
* SkewedPriorities: Bill and Ted try to get Christopher Columbus to discover America, because if he doesn't it would mean... no Columbus Day, which would mean ''one extra day of school!''
* TakeThat: "The Birth Of Rock And Roll, or: Too Hip For The Womb" featured a veiled Take That to Music/NewKidsOnTheBlock, who had their own cartoon show on Creator/{{ABC}} that same season. (Ironically, [=DiC=] Entertainment, which produced the New Kids On The Block cartoon, would take over the production for the second season of this show.) Bill and Ted meet Rufus at a record store:
-->'''Rufus:''' I was just checking out this new album by New Boys On The Corner.
-->'''Bill and Ted:''' And?
-->'''Rufus:''' They stink.
* WhenIWasYourAge: Ted's Dad lectures the boys this way.
* WhosOnFirst: Season 1 episode "Never Shall the Twain Meet" had the boys looking for Creator/MarkTwain. They find Sam Clemens on a riverboat, shouting "Mark Twain!", causing them to ask "Where?!" Clemens explains what the term means, but the next time he gives out the call, they again ask "Where?!"
* YourTomcatIsPregnant: One episode featured a rare bird that met its demise (or else escaped) while under the care of our intrepid heroes, causing them to scramble for a replacement. Thanks to their [[MacGuffin time-travelling phone booth]] they manage to snag one from its country of origin, with a twist. The original was a male bird. The replacement was a female bird. This is discovered when she lays an egg.
