History ShoutOut / FostersHomeForImaginaryFriends

* In the credits gag of [[WesternAnimation/HouseOfBloos one of the parts of the pilot movie]], Bloo is flipping through the channels, and finally decides on one. You can hear audio from Craig's earlier cartoon, ''WesternAnimation/ThePowerPuffGirls'', with the narrator saying his CatchPhrase.

-->'''Wilt:''' WhoYaGonnaCall?\\

* In the credits gag of the first episode, Bloo is flipping through the channels, and finally decides on one. You can hear audio from Craig's earlier cartoon, ''WesternAnimation/ThePowerPuffGirls'', with the narrator saying his CatchPhrase.
* Plenty of shout-outs to ''Franchise/TheHitchhikersGuideToTheGalaxy'' as well, though. For instance, the villain from the video game Bloo plays is called "Lord Beeblebrox" and the two nerdy scientists who study Coco are called [[Creator/DouglasAdams Douglas and Adam]], respectively. Adam wears a blue t-shirt with the number 42 on it.
** There's also a scene in the episode in which Bloo steals the Foster's bus which has a hitchhiker wearing a bathrobe holding a sign that says "Magrathea." In the same episode, there is a Star Wars shout out when Mac throws money for a toll out the window and misses to which Bloo responds "Negative, it didn't go in. It just impacted on the surface."
** In yet ANOTHER (much more obscure) Hitchhikers reference, the friends unite together to rescue a cat from a tree using what Frankie calls "Plan Z-Z-9-Plural Z-Alpha".

* The episode ''Bye Bye Nerdy'' gives us this exchange between Bloo and Frankie:
-->'''Bloo:''' [[Film/TheBluesBrothers It's a hundred and six blocks to Mac, I've got a full bladder, half a mind where I'm going, it's Tuesday and I'm wearing]] [[CoolShades sunglasses.]]\\
'''Frankie:''' ''* opens window* '' hit it!
* Frankie's t-shirt (that she wears 99% of the time) has a Stylized image of WesternAnimation/ThePowerpuffGirls.
** Similarly, in the episode where Eduardo gets fleas, the flea mayor looks and sounds strangely familiar.
** In the pilot movie, while Wilt, Coco and Eduardo are taking Mac and Bloo showing them allmthe imaginary friends, Mojo Jojo appears while Wilt is talking about "unimaginative friends" that kids just copy off of TV.
** "Challenge of the Superfriends" begins with Tom Kenny's voice saying "The City", and ends with Bloo saying "Once again, the day is saved", and for a moment, Bloo adopts Mojo Jojo's speech patterns.
** "Nightmare on Wilson Way" has Frankie dress as Blossom for Halloween while Bloo went as Mojo Jojo a previous year.
** In "Destination Imagination", one of Frankie's potential replacements wears a t-shirt with a stylized picture of Mojo Jojo to parallel her own.

* In ''Partying is Such Sweet Soiree'', when Mac is telling Bloo that he doesn't want to see him get in trouble again, Bloo responds by saying "[[Music/Beastie Boys Do I have to fight for my right to party?]]"

* A tall basket ball player named Wilt? That's a reference to Wilt Chamberlain.

* A tall basket ball player named Wilt? C'mon guys, that's an easy one.[[note]]In case it ''wasn't'' easy, it's a reference to Wilt Chamberlain.[[/note]]

* Mac names one of the [[spoiler:imaginary]] puppies in ''Who Let The Dogs In?'' "Buckaroo." Craig [=McCracken=] has cited ''Film/TheAdventuresOfBuckarooBanzaiAcrossThe8thDimension'' as his favorite movie.
* As a bit of self-referential humor, the episode "One False Movie" references the creators of the show. The titular protagonist of Eduardo's favorite show "Lauren is Explorin" is named after the series's lead writer, Lauren Faust, who is also the wife of the series's creator [[Creator/CraigMcCracken Craig McCracken]].
** Later on, the show is revealed to have been created by an animated version of McCracken, who is voiced by himself.

* In Blooooo, Bloo's hallucinated reflection looks at him and says [[Film/ForrestGump "Run, Bloo, run!"]]

* "Challenge of the Superfriends" contained some pretty blatant references to [[StarWars Revenge of the Sith]]. Bloo is clearly meant to be a CaptainErsatz of Darth Vader in this, with Nemesis as Darth Sidious.

* In Blooooo, Bloo's hallucinated reflection looks at him and says [[StarWars "Run, Bloo, run!"]]

* At the end of "Bloo Superdude & the Great Creator of Everything's Awesome Ceremony of Fun That He's Not Invited To", a hallucinating Frankie imagines herself in a science fiction scene very reminiscent of ''Film/{{Barbarella}}''... a movie, it should be noted, that is [[GettingCrapPastTheRadar very nearly porn]].

* The forest cottage Eduardo gets sent to in "Read 'Em and Weep" resembles the one in ''WesternAnimation/SleepingBeauty''.
