* One of the [[MultipleEndings six non-canon endings]] of the last episode of ''Machinima/RedVsBlue'' showed that the whole series was just an overly long Halo 2 multiplayer match.

* An episode of ''Machinima/FreemansMind'' had Freeman see Mike and Dave from ''Machinima/CivilProtection'' on their lunch break, excitedly proclaiming they were going to get tacos.

* Season 3 of ''Anime/SpacePatrolLuluco'' features references to previous ''Creator/StudioTrigger'' works for four episodes in a row, each one more blatant than the last. Episode 7 confirms the existence of Life Fibers in the universe, features a planet named KLK-X, plays "Before my Body is Dry", and even has an alien that looks like Guts, but ''Anime/KillLaKill'' is not even mentioned once in the episode. Episode 8 takes place on the world of ''Anime/LittleWitchAcademia'' and features an extended cameo from Sucy Manbavaran. The first half of episode 9 is for all intents and purposes a sequel to ''SEX and VIOLENCE with MACHSPEED'', with Luluco shoved into the background. Finally, episode 10 reveals that ''WebAnimation/InfernoCop'' is a member of the Space Patrol. All of this leads up to [[spoiler:TheReveal of Luluco being one of the three mascots of Studio Trigger, Trigger-chan.]]

* The webcomic ''Webcomic/TheKamics'' has done this [[http://www.theduckwebcomics.com/The_KAMics/4771842/ once]] or [[http://www.theduckwebcomics.com/The_KAMics/4815086/ twice]].
* The [[http://tw-babiez.livejournal.com/17102.html last page]] of ''WebComic/TorchwoodBabiez'' features Franchise/{{Batman}}.

* [[http://fav.me/d1bwemo This]] ''WesternAnimation/EdEddNEddy'' fancomic features a surprise appearance of [[WesternAnimation/TheFairlyOddParents Denzel Crocker]] in the last panel, giving an F like he always does.

* At the very end of the 1944 Creator/BobHope film ''Film/ThePrincessAndThePirate'', Bob thinks he's won the girl, only for her to rush past him and into the arms of his [[Film/RoadTo Road Picture]] co-star Music/BingCrosby, who had not been in the picture heretofore.

* In episode 8 of ''WebAnimation/InanimateInsanity II'', once the contests reach Meeple headquarters they hear a voice (at the moment unknown to them) belonging to Steve Cobs. When they try to see who the voice belongs to, we see Gamey, the host of ''Object Overload'' (another popular object show), who points them towards Cobs.

* At one point in ''Anime/TheBigO'', Roger Smith (who's a noted Franchise/{{Batman}} {{Expy}}) is approached by a pair of reporters that look ''exactly'' like Lois Lane and Jimmy Olsen.

* In [=ZaSu=] Pitts & Thelma Todd's ''On the Loose'', the duo are driven to distraction by the fact that all the men they date only ever want to take them to the Coney Island amusement park. At the end, they finally snap when asked out for yet another trip to Coney Island by their new neighbours -- Creator/LaurelAndHardy.

[[folder:Pro Wrestling]]

* Before making an official return to Wrestling/{{CMLL}}, Dr. Wagner Jr made brief appearances threatening revenge against Ultimo Guerrero and Atlantis. These were little nods to independent promotion Lucha Liga Elite, which was featuring Wagner on television, something CMLL lacked at the time.[[/folder]]

* ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'':
** In the episode "My Fair Mandy", Mandy enters a child beauty pageant in order to show up her arch-rival Mindy, and is coached that she would win if she would simply smile. With great effort, Mandy begins to smile, and [[RealityBreakingParadox reality shatters]], placing Billy, Mandy and Grim in Townsville as distorted [[WesternAnimation/ThePowerpuffGirls Powerpuff Girls]] with Irwin as Mojo Jojo. They even got Tom Kane to play Professor Utonium and Tom Kenny to play the PPG Narrator!
** There are several cameos from [[WesternAnimation/EvilConCarne Hector Con Carne]], with which they originally shared a ThreeShorts program with (''Grim and Evil''). On one of these occasions, annoyed by the situation, Hector states that "I'm not even supposed to be on this stupid show anymore!" This also applies to any time General Skarr appears, since he debuted on that show.
** The short "Dream Date" ended by revealing it to be a DreamWithinADream within a dream within a dream within [[WesternAnimation/FostersHomeForImaginaryFriends Wilt's]] head.
--->'''Wilt:''' I'm sorry, but what a weird dream. I don't even know any of those people!
** In TheMovie ''Billy and Mandy's Big Boogey Adventure'', when they ask who's going to be the Grim Reaper now that Grim has been removed from the position, [[WesternAnimation/CodenameKidsNextDoor Numbuh Three]] shows up in a portal, wielding the scythe and thanking Boogey for the new job opportunity. The two shows did eventually crossover as ''The Grim Adventures of the Kids Next Door''.
** Speaking of the crossover episode, when Billy wore his dad's "lucky" pants, which kicked off the entire episode [[ItMakesSenseInContext and nearly destroyed all civilization as a result]], the KND weren't even the first call he made. No, he called [[WesternAnimation/EdEddNEddy Eddy]] first, who ''then'' directed him to the Kids Next Door upon learning he's broke. [[OverlyLongGag And then when they show up at his door, he exclaims,]] "Hey, you're not WesternAnimation/ThePowerPuffGirls!" The episode as a whole has at least one character from every series produced for Creator/CartoonNetwork up to that point appear as cameos, and TheStinger features fake posters a number of joke crossovers (''[[WesternAnimation/EdEddNEddy Ed, Edd n]] [[WesternAnimation/TheGrimAdventuresOfBillyAndMandy Mandy]]'', ''[[WesternAnimation/EvilConCarne Evil]] [[WesternAnimation/CampLazlo Camp]] [[WesternAnimation/EvilConCarne Carne]]'', ''[[WesternAnimation/ClassOf3000 Class of]] [[WesternAnimation/CodenameKidsNextDoor Numbuh]] [[WesternAnimation/ClassOf3000 3000]]'', ''[[WesternAnimation/MyGymPartnersAMonkey My Gym Partner's A]] [[WesternAnimation/DextersLaboratory Mandark]]'', and ''[[WesternAnimation/SamuraiJack Samurai]] [[WesternAnimation/FostersHomeForImaginaryFriends Mac]]'').
** "Billy and Mandy Moon the Moon" ends with the alien leader attempting to learn Earthling secrets by drinking brain juice harvested from five typical Earthlings. Drinking the brain juice instead turns him into a babbling dum-dum, afterwards it is revealed that the brain juice was harvested from moronic characters Fred Fredburger, Ed from ''WesternAnimation/EdEddNEddy'', Skip from ''WesternAnimation/CampLazlo'', Cheese from ''WesternAnimation/FostersHomeForImaginaryFriends'' and Slips Python from ''WesternAnimation/MyGymPartnersAMonkey''.
* In the ''WesternAnimation/CodenameKidsNextDoor'' episode "Operation: G.R.A.D.U.A.T.E.", when hit by the Animalization Ray, the Delightful Children from Down the Lane are turned into sheep with similar appearances to the title character from ''WesternAnimation/SheepInTheBigCity'', with Bruce bearing the strongest resemblance to Sheep.
* One of the final shots in ''WesternAnimation/OverTheGardenWall'', that being a bird-eye view of Wirt and Greg's hometown, implies that the brothers live ([[TwentyMinutesIntoThePast or lived]]) in the town of Aberdale, the setting of fellow Creator/CartoonNetwork production ''WesternAnimation/{{Clarence}}''.
* ''WesternAnimation/Sealab2021'': The ending of the episode "Murphy Murph and the Feng Shui Bunch" revealed that the events of the episode were part of a video game being played by Meatwad and Master Shake of ''WesternAnimation/AquaTeenHungerForce''. ("You hang windchimes for an hour, and then you fight? I don't get it.")
* ''WesternAnimation/FamilyGuy'':
** The ending of the episode "Da Boom" has it be AllJustADream by Pam Ewing of ''Series/{{Dallas}}'', who finds her husband Bobby in the shower, in a parody of the famous [[TheReveal reveal]].
** In the fourth season, the main plot of one episode is a parody of ''Film/{{Poltergeist|1982}}'', which has Peter replicating the scene where a character pulls the skin off his face while looking in the mirror. When it all comes off, he has turned into [[WesternAnimation/KingOfTheHill Hank Hill]]:
--->'''Peter/Hank:''' Hehehehehehe. Propane.
** On the fifth season finale "Meet the Quagmires", after Peter apparently fixes every problem from his screwing with the timeline, Roger Smith from ''WesternAnimation/AmericanDad'' suddenly appears.
** In "Lois Kills Stewie" (which was just a [[AllJustADream simulation]]) Stewie breaks into the CIA and is confronted by Bullock and Stan, the latter of which Stewie mistakenly calls "Joe", lampshading how Stan [[ReusedCharacterDesign looks like Joe Swanson with black hair]].
** During a ''Series/PoliceSquad'' spoof you get a JawsFirstPersonPerspective of Stewie running down [[WesternAnimation/TheSimpsons Homer Simpson]] as he parks in the garage.
--->'''Peter:''' ''[looks down at Homer]'' Who the hell is that?
** There's an episode that has a miniature Marge appear at the bottom of the screen and at first, it seems like one of Fox's advertisements... until a miniature Quagmire attempts to rape her.
** In the episode "The Splendid Source", Peter and his friends are going around the country questioning people about where they heard a particular joke. At one point we see them asking Bender from ''WesternAnimation/{{Futurama}}''.
** In "Excellence in Broadcasting" the normally far left-leaning Brian finds himself being swayed to the right-wing views of [[InkSuitActor guest star]] Radio/RushLimbaugh. We switch to Ultra Conservative [[WesternAnimation/AmericanDad Stan Smith]] watching the episode saying "Good. Good for Brian."
** A cold opening for one episode crosses over with ''WesternAnimation/AmericanDad'', which turns out to be a DreamWithinADream of [[WesternAnimation/KingOfTheHill Hank Hill]].
** At the end of the ''Film/SpiesLikeUs'' parody episode, a rocket wipes out [[WesternAnimation/TheClevelandShow Cleveland]]'s new home, sending Cleveland in his bathtub crashing to the ground, a ''WesternAnimation/FamilyGuy'' running joke. Cue Tim the Bear to walk out a second later.
--->'''Tim:''' I don't get it!
** In the episode "The Simpsons Guy" (itself a crossover with ''WesternAnimation/TheSimpsons''), the judge in the second half of the episode is [[WesternAnimation/TheFlintstones Fred Flintstone]].
** Later in the same episode, when Kang and Kodos are watching Homer and Peter fight each other, Roger suddenly appears on their spaceship... right before Peter and Homer crash into it.
*** [[OverlyLongGag Earlier]], Peter sets up a CutawayGag with him and Homer fighting in a plane where a third pilot is revealed to be [[WesternAnimation/BobsBurgers Bob Belcher]]. This turns out to just be the setup to [[SelfDeprecation a joke about]] ''WesternAnimation/TheClevelandShow''.
** In "Ratings Guy", just after Peter arrives at the Television Producers Guild to make up for ruining the state of television, Homer Simpson (complete with Creator/DanCastellaneta voicing him) runs in with the same problem Peter has, prompting Peter to gloat about [[ItsBeenDone having one over him]].
** In "Killer Queen" after finding a boy attending fat camp with them dead Peter wonders who would kill a camper, at which point [[Franchise/FridayThe13th Jason Voorhees]] says [[NotMeThisTime not to look at him]], as he was just there to drop off his son.
*** [[WesternAnimation/AmericanDad Barry Robinson]] also appeared in this episode but had no real lines.
** The ending of "Trans-Fat" featured the cast of ''WesternAnimation/BobsBurgers''. [[FlameBait That scene was a bit controversial as]] [[TakeThat Peter was mocking their show]].
** Really due to the [[ReferenceOverdosed nature]] of the show, there are too many here to list them all.
* [[WesternAnimation/TheSimpsons Homer Simpson]] appeared at the end of one episode of ''WesternAnimation/{{Duckman}}''.
* ''WesternAnimation/TheSimpsons'' has several examples:
** The cameo appearance of the ''WesternAnimation/KingOfTheHill'' cast in the episode "Bart Star": after a football game ends, Hank shows up and proceeds to complain about it not being worth driving 2000 miles for and, if you look closely, Dale and Boomhauer can be seen in the stands as well.
** As might the throwaway gag of the ''ComicBook/ArchieComics'' gang throwing Homer out of a van and warning him to "stay out of Riverdale". He is later seen reading an Archie comic and muttering under his breath about "stuck-up Riverdale punks".
*** A later episode, "How Lisa Got Her Marge Back", had the Riverdale gang pulling a prank on Bart before mourning Archie (a reference to Archie's death in ''ComicBook/LifeWithArchieTheMarriedLife'').
** In a WesternAnimation/TreehouseOfHorror episode, Homer makes multiple clones of himself. Peter Griffin can be seen amongst the clones as a TakeThat to the popular opinion that ''WesternAnimation/FamilyGuy'' is a ripoff of ''The Simpsons''.
** Similarly, in one episode the police have photos of several criminals wanted in Italy. Two of them are Peter Griffin (for plagiarism) and [[WesternAnimation/AmericanDad Stan Smith]] (for plagiarism of plagiarism).
** In another episode, Future-Drama, Bender from ''WesternAnimation/{{Futurama}}'' appears next to Bart and Homer after they travel through a time tunnel. Homer quickly proceeds to tell him to "get lost" and chucks him out of a moving vehicle.
** He appears again later in the Simpsons basement as a callback to the actual crossover ''Simpsorama'' they now use him as a safe.
** He appears again during [[LiveEpisode "Homer Live"]] holding up a sign saying "Bring back Futurama [[UnCancelled (again)]]".
** [[WesternAnimation/{{Futurama}} Philip J. Fry]] also appears briefly in a couch gag.
** Another CouchGag involved Franchise/RickAndMorty crashing into the Simpsons household, killing the family in the process. Rick sends Morty off to get the family cloned, while Rick loots their house and freezes Ned Flanders.
** Another couch gag has the Simpsons running in only to find ''WesternAnimation/TheFlintstones'' in their place.
** The couch gag for the first episode of season 28 is [[https://www.youtube.com/watch?v=E8gDvbsYd0Q a reanimation]] of the ''WesternAnimation/AdventureTime'' opening, complete with parody lyrics and ContinuityPorn.
** In one Treehouse of Horror wherein Homer travels through time, Kang and Kodos turn into Mr. Peabody and Sherman from ''WesternAnimation/RockyAndBullwinkle'' [[TemptingFate after saying that]] the PunyEarthling [[HypocriticalHumor was unprepared for the effects of time travel]]. Doubles as a BrickJoke because they were seen near the beginning of the short [[ItsBeenDone correcting Homer saying he was the first non-Brazilian person to travel through time.]]
** In one episode set in an insane asylum we see a number of the inmates... including [[WesternAnimation/TheCritic Jay Sherman]].
--->'''Jay Sherman:''' [[CatchPhrase It stinks! It stinks! It stinks! It stinks!]]\\
'''Asylum Attendendant:''' Yes, Mr Sherman. Everything stinks.
** He returns, with every other character Creator/JonLovitz has ever played in the show, to greet Artie Ziff at Moe's. Artie calls them [[HypocriticalHumor weirdos.]]
** In "Fear of Flying" Homer is forced to find another bar after getting kicked out of Moe's and at one point finds himself at ''Series/{{Cheers}}''.
** The CouchGag for "My Way or the Highway to Heaven" has Homer ending up in the intro to ''WesternAnimation/BobsBurgers'', where he suffers all the disasters that strike the restaurant (including a pest infestation and a fire) in real-time while the Belchers wonder what he's doing in their restaurant.
* One episode of ''WesternAnimation/{{Chowder}}'' has a character waiting for a blind date. In walks Sara Bellum from ''WesternAnimation/ThePowerpuffGirls'' -- but she's not his date.
* ''WesternAnimation/RobotChicken'':
** One sketch parodying ''Franchise/SpiderMan'' featured a teenage boy getting bitten by a [[ILoveNuclearPower radioactive deer]] and becoming [[AnimalThemedSuperBeing "Kid]] [[WhatKindOfLamePowerIsHeartAnyway Venison"]]. At the end of the sketch he is hit by a car. After this we see a sketch parodying ''Franchise/{{Terminator}}'' which ends with Sarah Connor hitting Kid Venison with her car.
** TheStinger for the [[ADayInTheLimelight Bitch Pudding Special]] has Nick Fury appear, presumably to offer her a place in Film/{{The Avengers|2012}}. She then proceeds to car-jack him.
* ''WesternAnimation/AmericanDad'':
** An episode features Stan name his top ten favorite fictional dogs. The #1 spot belongs to Brian from ''WesternAnimation/FamilyGuy'' who appears and doesn't know who Stan is.
--->'''Stan:''' [[TakeThat STOP PRETENDING I DON'T EXIST!]]
** In the episode "The Unbrave One", Francine takes several online pregnancy tests from a shady gynecologist named Dr. Vadgers, most of which involve naked close-ups. The end of the episode shows Dr. Vadgers's computer screen, then reveal him to be [[WesternAnimation/FamilyGuy Quagmire]].
** After the family's house is washed away in a hurricane it arrives next door to [[WesternAnimation/TheClevelandShow Cleveland's]]. At which point [[WesternAnimation/FamilyGuy Peter Griffin]] appears and the three are armed with guns at each other. Then Stan accidentally shoots Francine:
--->'''Peter:''' Heh-heh-heh-heh-heh-heh. Classic ''American Dad''.
* An episode of ''WesternAnimation/TimeSquad'' had Buck and Larry abandon Otto after a fight and try out several replacement orphans... including [[WesternAnimation/DextersLaboratory Dexter]], who protests he's not an orphan.
* ''WesternAnimation/HouseOfMouse'' had one in one of its episodes. With ''WesternAnimation/PepperAnn'' of all shows! But considering it's a MassiveMultiplayerCrossover, nine-tenths of the jokes are going to be this.
* ''WesternAnimation/FostersHomeForImaginaryFriends'':
** The pilot also has an imaginary friend who is [[WesternAnimation/ThePowerpuffGirls Mojo Jojo]]; according to Wilt this is pretty common since "some kids aren't that creative, so they just copy what they see on TV."
** A quick joke in one episode shows [[WesternAnimation/TheGrimAdventuresOfBillyAndMandy Mandy]] returning an imaginary friend, saying it was too happy. To make it funnier, said scene is just in Bloo's imagination.
* ''WesternAnimation/{{Animaniacs}}'' would occasionally cross the characters of its various shorts for a quick gag. A couple times, the Warners would be at a loss for how to deal with their current problem and eventually resort to recruiting another character: they took care of [[WesternAnimation/TinyToonAdventures Elmyra]] by heading for Mindy and Buttons' neighborhood and letting her fill Buttons' usual BadlyBatteredBabysitter duties; and for a lady with KarmicProtection as a genuine (if overbearingly) [[NiceGuy Nice Girl]] they hired Slappy Squirrel, who had no such scruples. In yet another short, it was revealed that the dragon they just beat was actually a machine controlled by WesternAnimation/PinkyAndTheBrain.
* In ''[[WesternAnimation/UltimateSpiderMan2012 Ultimate Spider-Man]]'', the Living Laser is thrown into a dimensional rift, and comes out in the world of ''WesternAnimation/TheSuperHeroSquadShow'', getting promptly beaten up by SHS-Thor.
* An episode of ''WesternAnimation/RoadRovers'' had the villain being incarcerated in an insane asylum for megalomaniacs, along with several other villains from previous episodes. The inmates end up yelling at each other from their cells, arguing about about who is going to rule the world, until at the end a familiar voice is heard...
-->'''[[WesternAnimation/PinkyAndTheBrain The Brain]]''': No, it is '''I''' who shall rule the world! YES!\\
''(the closing theme of'' Pinky and the Brain ''is heard as the episode fades to credits)''
* In an episode of ''WesternAnimation/Ben10Omniverse'' about a store that shifted between dimensions, when Ben first enters the store it's populated by alien versions of ''WesternAnimation/CowAndChicken''.
* One episode of ''WesternAnimation/OggyAndTheCockroaches'' has Oggy and the cockroaches falling into acid and turned into slime, and they enter a washing machine, which turns them into clothing, animals, then aliens... except that the "aliens" are clearly the titular characters of ''WesternAnimation/SpaceGoofs'' (both of which were produced by France's Gaumont studio).
* ''WesternAnimation/LooneyTunes'': Not counting "all-star" outings, there have been several instances of characters appearing in another character's starring roles.
** Near the end of the 1942 spot-gag short ''Crazy Cruise'', a group of rabbits are seen defending themselves from a Japanese vulture by donning air raid helmets and shooting a cannon at it. One of the rabbits, whose face has been obscured from the viewer, turns out to be WesternAnimation/BugsBunny, who tells the audience "Thumbs up, doc!" before the IrisOut closes on his ears, which form [[WartimeCartoon a "V" for victory]].
** In the 1943 short ''WesternAnimation/PorkyPigsFeat'', [[WesternAnimation/PorkyPig Porky]] and [[WesternAnimation/DaffyDuck Daffy]] are being held prisoner in their hotel room for not paying and wonder what Bugs would do in a situation like this. They decide call him up and, after he offers ideas they already tried and failed at, the door opens to reveal Bugs chained up in the room next to theirs ("Aah, don't work, do they?").
** In the 1954 short '"Dog Pounded'', Sylvester tries to retrieve Tweety from a dog pound by [[AssInALionSkin disguising himself as a skunk]] to scare the dogs away. It nearly works until he suddenly becomes the object of Pepe Le Pew's affection.
** In the 1954 short ''No Barking'', an alley cat tries to catch a bird from a tree, only for a dog to yap loudly give him a JumpScare that sends up flying up. The bird in the nest is revealed to be Tweety, who says [[CatchPhrase "I tawt I taw a putty tat"]]. He reappears at the end, watching the cat sent flying again and grasping an airborne jet, saying "I ''did'', I did taw a putty tat!" (Note: This was Tweety's only appearance in a Creator/ChuckJones cartoon, having previously been exclusive to those made by Creator/BobClampett and Creator/FrizFreleng.)
** The 1955 short ''Sahara Hare'', in which Bugs winds up in the Sahara Desert while digging his way to Miami Beach, ends with an appearance by Daffy Duck, [[HereWeGoAgain who is also going to Miami]].
** The 1959 short ''Apes of Wrath'', in which a drunken stork delivers Bugs to a gorilla couple, ends with said stork giving Bugs his own "baby": Daffy!
** In the 1964 short ''WesternAnimation/FalseHare'', a wolf and his nephew disguise themselves as rabbits to lure Bugs into a trap disguised as a "rabbit club". After several failed attempts at catching him, the wolf gives up and says he's starting a "rooster club" and [[HereWeGoAgain Foghorn Leghorn immediately appears to join]].
** In the 2014 CGI short ''Flash in the Pain'', Wile E. Coyote tries to catch the Road Runner by using a teleportation belt. When the belt malfunctions, Wile E. suddenly finds himself in Tweety and Sylvester's domain.
** Let's not forget the famous ending to ''WesternAnimation/DuckAmuck'', where the animator pestering Daffy turns out to be [[spoiler: Bugs Bunny]]. Or its lesser known sequel, ''WesternAnimation/RabbitRampage'', where Bugs is tormented by an animator who turns out to be [[spoiler: Elmer Fudd]].
* An ''extremely'' subtle example comes from ''WesternAnimation/RickAndMorty'' and ''WesternAnimation/GravityFalls''. In "Close Rick-counters of the Rick Kind", Rick opens up various portals to throw off the alternate Ricks pursuing him. A pad, pencil and coffee mug randomly drop out of one portal. In the ''Gravity Falls'' episode "Society of the Blind Eye" [[spoiler:when Grunkle Stan is fiddling with the portal]], those exact items get sucked in. The coffee mug even has a question mark on it in both shows.
* ''WesternAnimation/FutureWorm'''s "Finale" episode has Danny and Future-Worm [[spoiler: riding the Time Deer and briefly teleporting into the universes of other Disney XD shows:]] ''WesternAnimation/StarVsTheForcesOfEvil'', ''WesternAnimation/PickleAndPeanut'', ''WesternAnimation/WanderOverYonder'', and ''WesternAnimation/GravityFalls''. In the case of the latter, it's plausible as an off-screen moment at the end of "Dungeons, Dungeons, and More Dungeons".
* In the ''WesternAnimation/{{Freakazoid}}'' episode "[[Series/QuantumLeap Quantum Freak]]", Freakazoid "prevents World War II"[[note]]which had actually been ongoing for two years in the rest of the world[[/note]] by preventing the Japanese assault on Pearl Harbor, then goes back to the present time to [[RippleEffectProofMemory see what changes it brought]]. Similar to the episode's beginning, UsefulNotes/AirForceOne is in peril and its pilot bailed, only this time the president is [[WesternAnimation/{{Animaniacs}} The]] [[WesternAnimation/PinkyAndTheBrain Brain]], and the staffer trying to fly the plane is now Pinky.
** Another episode featured [[WesternAnimation/{{Animaniacs}} Wakko]] appearing along with the Brain. They all argue over which of their cartoons is Creator/StevenSpielberg's favorite. They go to Spielberg himself and ask him to which he simply says, "Who are you people?".
* The George Pal Puppetoon "Jasper Goes Hunting" has Jasper and Scarecrow encountering an ink-and-paint WesternAnimation/BugsBunny, who is ushered in the scene with an ersatz rendition of the Merrie Melodies theme. Bugs soon realizes he's in the wrong picture and dives back into his hole.
* The ''WesternAnimation/DextersLaboratory'' episode "Dad Is Disturbed" had Mom interrupting Dad's golf game by talking on the phone with "Betty". Dad gets her to stop by going to the other end, revealing that Mom was talking with a modern version of Betty Rubble from ''WesternAnimation/TheFlintstones''. At the episode's end, he goes back to the same house to watch the game with Barney.
* ''WesternAnimation/{{Futurama}}'':
** One episode had Fry, Leela and Bender go into the sewers to rescue Nibbler, when Leela pulls up a manhole cover. On the manhole cover was a picture of ''WesternAnimation/ThePJs'' as well at the show's title. They returned the favor in the episode "Cliffhangin' With Mr. Super" by having a shot of a milk carton with a "missing persons" alerts on the side. The missing person? Philip Fry, who by that time was cooling his heels in cryo-freeze.
** A later episode had Bender running into [[WesternAnimation/AdventureTime Finn the Human and]] [[ActorAllusion Jake the Dog]] and responding to the latter's "What time is it?" with "Time for you to shut up!"
* The crossover between ''WesternAnimation/UncleGrandpa'' and ''WesternAnimation/StevenUniverse'' ends with Uncle Grandpa reading a piece of paper listing characters from current and past Cartoon Network shows- plus, [[UnexpectedCharacter of all shows]], the [[WesternAnimation/SwatKats SWAT Kats]].
* The ''Uncle Grandpa'' episode "Pizza Eve" has a segment in which Uncle Grandpa is giving out "Grampies", and many characters from currently-airing and past Cartoon Network shows are attending. As one might expect when Uncle Grandpa is the host, he sweeps all the awards (including the "best ''Steven Universe'' episode" award), which is likely a TakeThat to the ''Kids Choice Awards'' over on Creator/{{Nickelodeon}} and how they tend to favor Nicktoons over all other shows.
* An episode of ''WesternAnimation/ThePowerpuffGirls'' had the girls battling an evil ImaginaryFriend; when their efforts prove fruitless, they realize they need their own imaginary friend. Bubbles starts to suggest the Koosalagoopagoop from ''WesternAnimation/DextersLaboratory'', only for Buttercup to shoot her down by saying "Not that Koos jerk!"
* An episode of ''WesternAnimation/{{Archer}}'' had the title character take on the persona of [[WesternAnimation/BobsBurgers Bob Belcher]]. The other Belcher family members appear, but only Linda has dialogue.
* An episode of ''WesternAnimation/TheFlintstones'' featured Fred and Wilma having a picnic. Their basket is stolen by none other than ''WesternAnimation/YogiBear''.
** Another Hanna-Barbera instance had Yogi Bear cameoing in an ''[[WesternAnimation/AugieDoggieAndDoggieDaddy Augie Doggie]]'' cartoon.
* Occurs in the Season 5 finale of ''WesternAnimation/{{Ninjago}}''. When Lloyd and Morrow have their battle, they wind up through several parallel realms, one of which being [[WesternAnimation/LegendsOfChima Chima]].
* The ''WesternAnimation/WeBareBears'' episode "[[HalloweenEpisode Charlie's Halloween Thing 2]]" features a segment where Charlie [[HumanityEnsues turns himself into a human]] via a magical carnival wishing machine to be able to leave the woods, only to end up flinging himself through multiple strange realities trying to turn back into a cryptid later, including one where Panda, Grizzly, and Ice Bear are [[WesternAnimation/AdventureTime Finn, Jake, and Ice King]] respectively (complete with a RoleReprise from Creator/TomKenny).
-->'''Ice King/Bear:''' Ice King in the wrong show.
* The ''WesternAnimation/WanderOverYonder'' episode "The Cartoon" ends on Lord Dominator switching TV channels from the titular cartoon attempt by Lord Hater to "The Mystery Kids' Mysteries", an amalgamation of ''WesternAnimation/TheJetsons'' and ''WesternAnimation/ScoobyDooWhereAreYou'' starring [[CaptainErsatz Captain Ersatzes]] of the cast from ''WesternAnimation/GravityFalls'', complete with their voice actors.
-->'''Alien Dog/Soos''': Ruff ruff! Ruff, I'm a dog, dudes!
* In ''WesternAnimation/TheClevelandShow'' episode "Hot Cocoa Bang Bang", we see [[WesternAnimation/TheSimpsons Comic Book Guy]] make a cameo appearance.
-->[[WorstWhateverEver "Worst. Cameo. Ever."]]
* ''WesternAnimation/TheCasagrandes'': In "Croaked", Carl is told on ''Dia de los Muertos'' that he has to spread marigold petals to form a path for their ancestors from the "land of the dead", leading him to [[LiteralMinded venture outside the apartment to make a long path to this "land"]]. At the end, when he finally uses up all the petals, he finds himself in front of [[WesternAnimation/TheLoudHouse the Loud residence]].

!!Examples:

* Season 3 of ''Anime/SpacePatrolLuluco'' features references to previous ''Creator/StudioTrigger'' works for four episodes in a row, each one more blatant than the last. Episode 7 confirms the existence of Life Fibers in the universe, features a planet named KLK-X, plays "Before my Body is Dry", and even has an alien that looks like Guts, but ''Anime/KillLaKill'' is not even mentioned once in the episode. Episode 8 takes place on the world of ''Anime/LittleWitchAcademia'' and features an extended cameo from Sucy Manbavaran. The first half of episode 9 is for all intents a purposes a sequel to ''SEX and VIOLENCE with MACHSPEED'', with Luluco shoved into the background. Finally, episode 10 reveals that ''WebAnimation/InfernoCop'' is a member of the Space Patrol. All of this leads up to [[spoiler:TheReveal of Luluco being one of the three mascots of Studio Trigger, Trigger-chan.]]

* ''Anime/ProjectAKo'' features a blink-and-you'll-miss-it gag at the end of the original OVA, where A-Ko's mother is seen sewing something that looked suspiciously like Franchise/{{Superman}}'s costume. The gag (that A-Ko is Superman and Franchise/WonderWoman's daughter) is made far more explicit in the Creator/AntarcticPress adaptation, where her parents refer to each other as "Clark" and "Diana".

** There are several cameos from [[WesternAnimation/EvilConCarne Hector Con Carne]], with which they originally shared a ThreeShorts program with (''Grim and Evil''). On one of these occasions, annoyed by the situation, states that "I'm not even supposed to be on this stupid show anymore!"

** "Billy and Mandy Moon the Moon" ends with the alien leader attempting to learn Earthling secrets by drinking brain juice harvested from five typical Earthlings. Drinking the brain juice instead turns him into a babbling dum-dum, afterwards it is revealed that the brain juice was harvested from moronic characters Fred Fredburger, Ed from ''WesternAnimation/EdEddNEddy'', Skip from ''WesternAnimation/CampLazlo'' Cheese from ''WesternAnimation/FostersHomeForImaginaryFriends'' and Slips Python from ''WesternAnimation/MyGymPartnersAMonkey''.

* "Billy and Mandy Moon the Moon" ends with the alien leader attempting to learn Earthling secrets by drinking brain juice harvested from five typical Earthlings.

* In the ''WesternAnimation/CodenameKidsNextDoor'' episode "Operation: G.R.A.D.U.A.T.E.", when hit by the Animalization Ray one of the Delightfuls is transformed into the title character from ''WesternAnimation/SheepInTheBigCity''.
