->''"Ladies and Gentlemen, Mister Burt Bacharach!"''
-->-- ''Film/AustinPowers''

A star brought into a series, to [[AsHimself star as himself]] or a character very similar to one he is famous for playing. In American television, this is common during UsefulNotes/{{Sweeps}}. Especially likely on a VerySpecialEpisode. The technical term is "StuntCasting." In a sitcom, always accompanied by [[LaughTrack canned cheering and applause]]. Pioneered on ''Series/ILoveLucy.''

* The Advertising/AirNewZealandSafetyVideos have had such guests as Creator/BettyWhite, Richard Simmons, Bear Grylls, the New Zealand All Blacks and the ''Magazine/SportsIllustrated'' swimsuit models.

[[folder:Anime & Manga]]
* ''Anime/LuckyStar'' had several seiyuus who were involved in ''LightNovel/HaruhiSuzumiya'' guest star as themselves. Creator/MinoruShiraishi and Creator/DaisukeOno were co-hosts on the "Lucky Channel" section of the show. Creator/AyaHirano (sort of) and Creator/YukoGoto guest starred in the show itself. Interestingly, in the English dub, they were voiced by the actors that portrayed their characters in the ''Anime/HaruhiSuzumiya'' dub. It's kind of funny hearing Creator/JohnnyYongBosch introduce himself as Daisuke Ono on Lucky Channel.
* ''Manga/DetectiveConan'' had the Detective League meet the Music-Duo Two-Mix, who sing the OpeningTheme and EndingTheme of the series, and the female member of the group is the voice actor for Conan. Naturally, all the characters did some LampshadeHanging on this similarity. The only difference between the two vocally is that Conan can't sing even if his life depended on it. This fact is especially evident when he has to fill in at a concert for her later on (Behind the scenes, of course).
* ''Anime/MarginalNumber4'' had Yokoo Lui, the series' choreographer (who is also a stage play actor known for portraying ''Music/{{Tsukiuta}}'''s Koi, and other roles), appear in episode 10 as the dance teacher at the idols' training camp.
* ''Manga/SoreGaSeiyuu'' has an in-universe example where Creator/YukariTamura takes part in a radio show. Naturally, she doesn't look a day over 17.
* ''Anime/YuriOnIce'' has two former professional figure skaters guest star as themselves in the last two episodes; Nobunari Oda appears as a commentator for the Grand Prix Finals in Episode 11, and Stéphane Lambiel appears in Episode 12 as a reporter for the same event.

[[folder:Comic Books]]
* In ''Angel: After the Fall'' (based on the Joss Whedon-created TV series), Gwen goes on a date with an actor named 'Nate', who bears a striking resemblance to actor (and comic book fan) Nathan Fillion--who starred in the Joss Whedon-created TV series ''Series/{{Firefly}}'' (and the last few episodes of ''Series/BuffyTheVampireSlayer'').

* ''Ocean's Twelve'': Tess pretends to be Creator/JuliaRoberts at one point, [[spoiler:but is found out when Creator/BruceWillis appears, and receives a call from the "real" Julia Roberts.]]

[[folder:Live Action TV]]
* ''Series/HeeHaw'': While there were "special guests" every week, the one guest that producer/creator Sam Louvillo wanted more than anybody came during the early 1970s ... but he never got him because Col. Tom Parker found out and quashed the idea immediately. That special guest that never was, of course, was Music/ElvisPresley. Additionally, Elvis ''wanted'' to be on the show and the negotiations were underway until Parker found out.
** Incidentally, in 1978, just months after Elvis' death, a TearJerker moment came when Elvis' father, Vernon Presley, make a guest appearance on the show to talk about his son's musical influences and how ''Hee Haw'' was one of his favorite programs.
* ''Series/FullHouse'', Michelle's friend Denise has a famous musician-uncle who turns out to be Little Richard.
** Music/TheBeachBoys also made frequent appearances as themselves throughout the series.
* ''Series/{{Friends}}'' has more than you can shake a stick at. Particularly in later series, when it was hugely popular, though it's interesting to spot occasional guest appearances early on by actors who would later ''become'' famous.
* ''Series/HowIMetYourMother'', which seems to have gotten its most fame ever from having Music/BritneySpears on twice. Not the first (or last) the show did, but definitely the most infamous. And Music/KatyPerry.
** And [[Series/ThePriceIsRight Bob Barker]] was supposedly Barney Stinson's father for a while.
* ''Series/JustShootMe'' featured guest appearances from various supermodels (most notably Rebecca Romijn, not as herself but as Finch's wife). Also, performers such as Robert Goulet and George Lucas have also appeared as one of Jack's old friends. Woody Allen appeared in an episode that featured a man who passed himself off as Woody Allen (the real Allen was only heard over the phone at the end), and Ray Liotta played himself as the cousin of RecurringCharacter Kevin.
* ''Series/LasVegas'' brought Creator/JeanClaudeVanDamme on to the show playing himself -- and then killed him off! In general, it had a star/celebrity every other episode it seemed.
* ''Series/TheNanny'' did this roughly every other episode. Once resulted in Creator/FranDrescher meeting herself, this only shattered the fabric of reality a little bit.
* ''Series/NewsRadio'': Subverted this by finding obscure people as writer in-jokes: Scott Adams (creator of ComicStrip/{{Dilbert}}), ''VideoGame/{{Defender}}'' creator Creator/EugeneJarvis and George "[[Series/TheAndyGriffithShow Goober]]" Lindsay (because they liked his autobiography). Then again, they did have their share of genuine guest stars (Jerry Seinfeld, James Caan, Bob Costas etc.), most of whose appearances went pretty awkwardly. (Interestingly, Seinfeld's own sitcom usually avoided such things, although even that had a few - Creator/BetteMidler, Creator/MarisaTomei
* ''Series/NightCourt'' had crooner Mel Torme show up and spend most of the episode just barely being missed by Judge Harry, who of course is a fanatical fan. This avoids being a CelebrityStar by virtue of the fact that this fandom had been long-established from the first episode of the series.
* ''Series/StarTrekTheNextGeneration'': In episode "Descent", Data is playing poker with holographic depictions of Stephen Hawking, Isaac Newton, and Albert Einstein. Hawking portrayed his own hologram for this episode. Apparently, he was just touring the set when the writers decided to put him in an episode and a few days later they filmed him. Giving Hawking the honor of being the only person to appear as himself in any ''Franchise/StarTrek'' show.
* ''Series/WhosTheBoss'', "Hit The Road Chad": Ray Charles comes to the Bauers' to play a few songs.
* The 1970s Toho-produced series ''Meteor Man Zone'' (known in the United States as ''Series/ZoneFighter'') had Gigan, King Ghidorah, and even Franchise/{{Godzilla}} as guest stars.
* ''Series/{{EXTRAS}}'': Ricky Gervais plays a professional film extra and meets at least one massive star each episode, always playing themselves. {{Lampshaded}} by the fact that every episode of the series was actually named after the main guest star of that episode ("Samuel L. Jackson", "David Bowie", "Daniel Radcliffe") and the fact that one episode revolved around the protagonist's disdain for Chris Martin having a far-fetched guest appearance on his ShowWithinAShow.
* ''Series/{{Arliss}}'': Arliss is a sports agent that has many big name sports clients.
* ''Series/{{Entourage}}'': follows the posse of a budding A-list movie star, who naturally shmoozes with some real-life A-list movie stars.
* ''Series/WillAndGrace'' was quite annoying with this; it featured special guests almost every week and seemed like a vehicle for celebrities to proclaim their gay-friendly status. Arguably the least egregious was Taye Diggs' extended stint as Will's boyfriend, since it was a surprisingly complex story arc and gave Will his first onscreen kiss (albeit in the final season). Extra points since it was both a gay and interracial romance on primetime TV.
** One episode suggests the show is set in an AlternateUniverse, where Creator/GeorgeTakei was still in the closet until publically outed on TV by Jack.
* An episode of ''Series/{{Moonlighting}}'' once featured Judd Nelson ''and'' Creator/WhoopiGoldberg as the special guest stars. If memory serves, they were actually quite good.
** Ray Charles also guested on an episode. As did Creator/OrsonWelles (introducing "The Dream Sequence Always Rings Twice," which aired after he passed away and was dedicated to him).
* ''Series/StargateSG1'' is quite popular amongst the actual USAF, and not just because it is BackedByThePentagon. Two consecutive Air Force chiefs of staff have appeared in the series, playing themselves. One episode featured O'Neill barging into General Hammond's office, loudly complaining (as usual) only to be introduced to General Michael E. Ryan, then-current Chief of Staff of the Air Force, whereupon O'Neill promptly quiets down. After filming was completed, Richard Dean Anderson asked General Ryan if he had any real Colonels as bad as Jack O'Neill, and Ryan responded that he had ''worse''. In the later episode Lost City, the second half featured General John P. Jumper (again, the then-current Air Force Chief of Staff) as himself during the Goa'uld attack, speaking with the President and coordiating the counter-atack. Apparently, when General Jumper first became the Chief of Staff, the first question he asked ''his'' staff was "When do I get to be on Stargate?"
* ''Law and Order'' and its spinoffs do this occasionally.
** For example, Lewis Black once played a Howard Stern-esque radio host.
** And Creator/CandiceBergen guest starred in ''Series/LawAndOrderTrialByJury'' as Judge Amanda Anderlee.
** The show also loves to cast comedians as the criminals, usually of the highly intelligent variety, including Martin Short, Creator/RobinWilliams, and Creator/StephenColbert.
* Most Creator/USANetwork originals do it all the time. Take a look at the list of guest stars through the seasons of ''Series/{{Monk}}''.
* Occasionally, a show will have [[CelebrityParadox a regular character's actor playing him- or herself]] (as the Special Guest) as well as the normal character. Usually this is accompanied by jokes about how similar they look.
** ''Series/MorkAndMindy'' had Mork meet Robin Williams in one episode.
** ''Sanford and Son'' had an episode where Fred Sanford enters a Redd Foxx lookalike contest; his son Lamont doesn't see the resemblance.
** Creator/LyndaCarter met Lucille Ball in an episode of ''Here's Lucy''.
* ''Series/{{Bones}}'' has an episode about dog fights featuring professional FluffyTamer Cesar Millan.
* ''Series/{{Castle}}'':
** Joe Torre, a baseball player and manager. [[TheCharmer Castle]] is fairly nonchalant, having met Joe before and not being overly interested in the game anyway, but Beckett can barely keep from {{Squee}}ing and immediately rushes off to call her dad to gloat.
** Chef Rocco Dispirito appeared in "Food to Die For" during [[TheCharmer Castle's]] date with Beckett's high school BFF.
** Richard Castle's poker game features real authors such as Creator/JamesPatterson and Creator/StephenJCannell; the latter's chair was left unoccupied after his passing ("No one sits there for at least a year").
* ''Series/TheIncredibleHulk's'' Creator/LouFerrigno moved next door to the Heffernans in ''Series/KingOfQueens''.
* Every episode of ''Series/PoliceSquad'' features a special guest... who would be killed before the opening credits were over. Creator/WilliamShatner lasted the longest, dodging a hail of bullets before finally succumbing to a poisoned drink.
* One episode of ''Series/SilverSpoons'' had Menudo attending the protagonist's birthday party as the entertainment.
* Subverted in one episode of ''Series/CSIMiami'': the suspect was a famous skateboarder who retired and made software games starring himself... but the SpecialGuest, [[VideoGame/TonyHawksProSkater Tony Hawk]], instead played the BodyOfTheWeek. [[spoiler: Also invoked, since Tony Hawk's character is also the CEO's StuntDouble for doing MotionCapture in the game, so he does skateboard in a flashback.]]
* ''Series/{{Chuck}}'' has taken stunt-casting to a whole new level, often having more than one guest star an episode.
* ''Series/TheYoungIndianaJonesChronicles'' was built around the concept of special guest stars who were actually historical figures. There are also several real stars who show up, several before the height of their fame. One episode features ''both'' Creator/CatherineZetaJones and Creator/DanielCraig before they peaked in popularity and movie star status.
* Every episode of ''Series/{{Batman}}'' had at least one "Special Guest Villain." While some, like Cesar Romero's Joker, Burgess Meredith's Penguin, and Frank Gorshin's Riddler, appeared often enough to almost be regular cast members, a great many were one-shot stunt castings of big-name stars (e.g., Milton Berle as Louie the Lilac, Art Carney as The Archer, Rudy Vallee as Lord Ffogg.)
** Also, celebrities would pop out of the window when Batman and Robin were climbing the building to talk to them.
** In January 1967, [[IdolSinger teen pop star]] Lesley Gore (of "It's My Party" fame) would appear in two consecutive episodes ("That Darn Catwoman" and "Scat! Darn Catwoman") as Pussycat, a minion of Catwoman; she would also lip-sync one of her then-current hit singles in each episode ("California Nights" and "Maybe Now", respectively).
* ''Series/AmericanDreams'' seemed to exist solely for this trope. Many episodes had a famous current musician appear as a famous 60's musician (often having nothing to do with the plot)[[note]]and some of them better known for things other than singing, like Music/HilaryDuff (as one of The Shangri-La's), Creator/JenniferLoveHewitt (as Nancy Sinatra - the future ''Series/GhostWhisperer'' was one of the few to appear more than once) and [[Creator/TyraBanks TYRA FREAKING BANKS]] (as one of the Marvelettes)[[/note]] and NBC would often make this the focal point of the advertising. One probably wouldn't even know the show had a plot unless they watched it.
* ''Series/HannahMontana'': About one in every six episodes of features a special guest or two - Hannah's "aunt" is Music/DollyParton[[note]]Music/MileyCyrus's godmother in real life[[/note]], [[Series/MamasFamily Mama]] is Miley's Mammaw. Lilly's mother turns out to be Heather Locklear, and as for Lilly's dad... as [[Series/GilmoreGirls Lorelai Gilmore]] once put it, "And yes, that is the guy from ''Series/TwoAndAHalfMen''." Their next door neighbor in season 4 is the [[AngusTJones half man]] from previous said show.
** Funny enough that Music/MileyCyrus and Creator/EmilyOsment later guest starred on ''Series/TwoAndAHalfMen'' another show set in a Malibu Beach House.
* ''Series/DoctorWho'' has done this a few times, with the likes of Sharon Osbourne and Richard Dawkins appearing in cameos as themselves, and even including stock footage of UsefulNotes/BarackObama in one episode, then bringing in a body double to make him part of the story ("The End of Time"). Several attempts at having members of the Royal Family appear as themselves have been unsuccessful. Back in 1965, the episode "The Chase" featured a guest appearance by Music/TheBeatles (via stock footage), as well.
* On ''Series/HomeImprovement'', several sports stars appeared as themselves as guests on the ShowWithinAShow ''Tool Time'', including George Foreman, Evander Holyfield, and Michael and Mario Andretti. Real life home improvement pioneer Bob Vila showed up several times. In one episode after Creator/PennAndTeller guest on ''Tool Time'', Tim is called out on this in-show, being told by fans that his show is relying too much on StuntCasting. Also, a few celebrities appeared as themselves outside of ''Tool Time'', including Music/TheBeachBoys (they're Wilson's cousins) and Rodney Dangerfield.
* ''Series/MontyPythonsFlyingCircus'': The ill-fated talk show called "It's" with singer Lulu ("To Sir With Love") and [[Music/TheBeatles Ringo Starr]] as guests with the tattered and bedraggled "It's" man as host. (Neither guest said anything.)
* ''Series/TheMuppetShow'' had a guest star in every episode. Justified, as the show is set in a theatre and revolves around a weekly presentation.
* Typically at least one per episode on the ''Series/ColgateComedyHour''.
* Martha Stewart in the first-season finale of ''Series/TwoBrokeGirls''.
* ''Series/ItsAlwaysSunnyInPhiladelphia'': Subverted in "The Gang Gets Invincible," where Donovan [=McNabb=] is promised to appear at the the Eagles football tryouts, but instead an obvious impostor played by Geoffrey Owens arrives and delivers a sales pitch for UsefulNotes/McDonalds. The gang realizes the fraud and vaguely recognizes the impostor as that guy from ''Series/TheCosbyShow''.
* ''Series/TheBigBangTheory'' often has guest stars playing themselves, which are either actors from shows popular amongst nerds (e.g. Creator/WilWheaton, Creator/LeVarBurton and Creator/BrentSpiner from ''Series/StarTrekTheNextGeneration''; Creator/KateeSackhoff from ''Series/BattlestarGalactica2003'', or Creator/SummerGlau from ''Series/{{Firefly}}'' and ''Series/TerminatorTheSarahConnorChronicles''), or popular RealLife scientists (e.g. UsefulNotes/NeilDeGrasseTyson, Creator/StephenHawking or [[Series/BillNyeTheScienceGuy Bill Nye]]). In most cases, though, it doesn't amount to more than TheCameo, while Wil Wheaton is more or less a RecurringCharacter.
* ''Series/KingOfTheNerds'' often has nerdy-fandom-related celebrity guests, usually to judge a competition. These have included Creator/GeorgeTakei, Creator/TaraStrong, and Series/BillNyeTheScienceGuy.
* {{Series/QI}} usually draws from a rather shallow pool of British comedians, but will also on occasion have a special guest who is somehow related to the topic of that episode. For example, Creator/DanielRadcliffe was a guest on "Magic" and Dr. Brian Cox appeared in "Incomprehensible".
* ''Series/MissionImpossible'' did this from time to time, such as in the third-season episode "The Contender" with former middleweight boxing champion Sugar Ray Robinson.
* The ''Series/CheckItOutWithDrSteveBrule'' special "Bagboy", a pilot created by Dr. Steve Brule, features Mickey Dolenz from Music/TheMonkees. He shows up for one scene near the beginning of the episode and never shows up again.
-->'''Mickey Dolenz:''' Excuse me, can you tell me where the bananas are?
-->'''Steve Brule:''' Who are you, some kinda monkey?
-->'''Mickey Dolenz:''' Actually, I am. ''(LaughTrack)''
-->'''Steve Brule:''' I know. [[DontExplainTheJoke He's, uh, one of the Monkees]]. From the show, ''[[Series/TheMonkees Monkees]]''. Hnhn. But the bananas are over there.
-->'''Mickey Dolenz:''' Ah, thanks. ''(Leaves)''
-->'''Steve Brule:''' That's it. That's the scene with Mickey Dolenz...Next scene.
* ''Series/That70sShow'' has many guest stars who used to act in 1970s sitcoms, such as Marion Ross and Tom Bosley (from ''Series/HappyDays''), Creator/BettyWhite, Valerie Harper, Gavin [=MacLeod=] and Creator/MaryTylerMoore from ''Series/TheMaryTylerMooreShow'', Creator/DonKnotts and Richard Kline from ''Series/ThreesCompany'', Tom Poston and Jack Riley from ''Series/TheBobNewhartShow'' and Eve Plumb, Barry Williams and Christopher Knight from ''Series/TheBradyBunch''.

* [[AWildRapperAppears Regularly happens nowadays where rap artists make guest appearances on other's records]].
* Carlos Music/{{Santana}} resurrected his career through liberal use of this trope on the ''Supernatural'' and ''Shaman'' albums.
* Music/{{Soulfly}}'s first few albums were built around this.
* Nelly's album ''Brass Knuckles'' had a guest star on every song. Fans who had waited four years for a worthy follow-up to ''Sweat/Suit'' weren't pleased.
* Music/TheRollingStones regularly have special guests join them onstage.
* Steve Miller regularly has his opening act join him onstage during his concerts.
* Music/CaptainBeefheart was the special guest on Music/FrankZappa's ''Music/HotRats'' where he sang the only track with lyrics, "Willie the Pimp."
* Radio entertainer Stanley Unwin narrates the tale of Happiness Stan in his own brand of idiosyncratic English on Music/TheSmallFaces' ''[[Music/OgdensNutGoneFlake Ogdens' Nut Gone Flake]]''.
* Almost every DJ ever uses a guest vocalist on a song-to-song basis.
* New Orleans' Trombone Shorty often features as one, as many acts these days don't have a horn player at all. His first two albums, ''Music/{{Backatown}}'' and ''For True'', relied fairly heavily on guest spots.

* One of the passengers in Creator/WilliamsElectronics' ''Pinball/{{Taxi}}'' is Pinball/PinBot, the star of Williams' top-selling game.
* ''VideoGame/{{Necronomicon}}'' features John Petrucci, guitarist for Music/DreamTheater, who contributed the music for the game's prologue and epilogue videos.
* Creator/SternPinball's ''[[Pinball/MustangStern Mustang]]'' has voice callouts from professional racing driver Tanner Foust.

* The 1973 Broadway musical ''Seesaw'' brought on Mayor John Lindsay of UsefulNotes/NewYorkCity during the "My City" number for one performance in its first week.

[[folder:Video Games]]
* ''Film/FightClub: The Video Game'': Fred Durst of Music/LimpBizkit is a bonus character.
* Music/MichaelJackson in ''VideoGame/SpaceChannel5''.
* The third-person shooter, ''Infected'' for the [[UsefulNotes/PlayStationPortable PSP]] has Mark Hunter, lead singer of ''Chimaira'', and the members of Music/{{Slipknot}}.
* ''VideoGame/DeusExInvisibleWar'' has the lead singer of Kidneythieves as a 2070s popstar.
* Denise Crosby as ''Series/StarTrekTheNextGeneration'' security chief Lt. Natasha Yar in ''VideoGame/StarTrekOnline'''s 3rd Aniversary mission: ''Temporal Ambassador''
* ''VideoGame/SpecOpsTheLine'' gives the player's profile name a SpecialGuest credit at the end of the opening credits.
* ''VideoGame/SaintsRowIV'' gives players the option to use Creator/NolanNorth 's voice. The option for his voice is even listed as "[[AsHimself Nolan North]]".
** ''Saints Row IV'' also features appearances by Creator/KeithDavid AsHimself [[spoiler:and Wrestling/RoddyPiper]].
* ''VideoGame/PAYDAY2'' has the Alesso Heist, set during a concert by the artist of the same name.

[[folder:Web Original]]
* ''WebVideo/KateModern'': A number of celebrities (of varying degrees of fame) cameo as themselves, including actor Jamie Bell; bands The Days and Scouting For Girls; film director Creator/MikeFiggis; presenters Tim Westwood, Nick Grimshaw, DJ Dre and Michael Underwood; journalist Gordon Smart; and Joanna Shields, the CEO of Bebo. None of them has significant impact on the plot.
* The boys from ''WebVideo/{{Unskippable}}'' tapped [[WebAnimation/ZeroPunctuation Ben "Yahtzee" Crosshaw]] for their ''VideoGame/StarOcean'' episode. And one of them appeared on ''WebAnimation/ZeroPunctuation'' to return the favor.
* Creator/KyleHebert reprised his role as the narrator for the second WebVideo/DragonBallZAbridged movie (in the Abridged Series itself, Creator/LittleKuriboh narrates), while Chuck Huber made an appearance in the WebVideo/YuYuHakushoAbridged movie as one of the villains (and provided an ActorAllusion -- he was Hiei in the dub).
** Kyle Hebert once more provided the voice of a narrator in an episode of WebAnimation/RanmaAbridged, in which he complains about his cameo being wasted and how everyone wants him to do the narrator voice.
*** Austin St. John cameo'd in ''WebVideo/KampferAbridged'' by Creator/MasakoX.
*** Chris Sabat appears in minor roles like the LemonyNarroter in the Bastion parody in the Super Android 13 movie as DJ Sexdillionare.
* ''Podcast/MuggleCast'' has had several with people from the ''Film/HarryPotter'' film franchise. Oh, and Rubeus Hagrid. Not Robbie Coltrane, but Rubeus Hagrid. The other ''Literature/HarryPotter'' podcast, ''[=PotterCast=]'', has also had plenty. Including Creator/JKRowling herself.
* ''WebVideo/TheNostalgiaCritic'' actually got Christopher Lloyd to say, "I was frozen today."
** Hell, Creator/MaraWilson showed up in one of his reviews, and she then later went on to co-review {{Film/Matilda}} with WebVideo/TheNostalgiaChick.
*** Creator/DonBluth guest starred in his 6th Commercials episode and his Dragon's Lair review.
* In ''Taco Man: The Game Master'', video game characters make apperences, This includes Dirk form ''Dragon's Lair''.
* ''WebVideo/{{Heartcore}}'' features characters created by the author's close friends. Said characters include Ryodalyn Knight (created by the author's best friend), Emerald Jaegar (created by [[http://sprite37.deviantart.com Cory Homles]], and Syranon Glaed (created by the author's husband).
* In ''WebVideo/EpicMealTime'':
** With Freddie "[[http://www.youtube.com/user/freddiew freddiew]]" Wong in "[[http://www.youtube.com/watch?v=jtWPW8yJtgM Epic VFX Time]]" and "[[http://www.youtube.com/watch?v=Ayi_FUlsqX0 West Coast Burger Pile]]" (alongside [[http://www.youtube.com/user/CorridorDigital Corridor Digital]]).
** With DJ/producer Music/{{deadmau5}} in "Cheesy Grilled Cheese Tower" and "Meat Cthulhu".
** With synthpop singer/songwriter Music/{{Lights}} in "Fast Food Meatloaf".
** With [=FPSRussia=] in "[[http://www.youtube.com/watch?v=kMyPD1VKk60 Russian Meal Time]]" and "Meat Shield".
** With professional skateboarder Tony Hawk in "Fast Food Pizza Cake".
** With the Music/{{SMOSH}} duo in "Super Pastry Cake".
** With as many as they could get in "Turbaconepicentipede", both old and new.
* The guys from The Gentleman's Rant are fond to bringing porn stars to the show. On the episode about homophobia, Brazzers stars Breanne Benson and Tasha Reign gave a shot at ranting and [[GirlOnGirlIsHot kissing]]. They also brought WebVideo/EpicMealTime's Harley for another episode.
* The WebVideo/{{React}} series:
** ''Kids React'': [[http://www.youtube.com/watch?v=crHfzQULoIE Lauren and Dani]] from Music/{{Cimorelli}}. Also, their younger brothers Joey and Christian participated in [[http://www.youtube.com/watch?v=aQrU_Omn1ZM "Kids React to 'It's Thanksgiving' (Nicole Westbrook)"]] and [[http://www.youtube.com/watch?v=sc1YWExO2dM "One Pound Fish"]] respectively.
** ''Teens React'': [[http://www.youtube.com/watch?v=KAVmF-dYv4U Lisa and Amy Cimorelli]] [[http://www.youtube.com/watch?v=A39cuQDl1GI and their brother Alex]], [[WebVideo/{{Fred}} Lucas Cruikshank]], Creator/JakeShort (twice), and [[http://www.youtube.com/watch?v=JlYM2UfiR4k Alex Steele]] from ''Series/{{Degrassi}}''.
** ''[=YouTubers=] React'' is virtually, "Special Guest: TheSeries".
* ''WebAnimation/HomestarRunner'':
** Parodied by the rapper Peacey P, who guest stars on ''his own albums''.
** Played straight in the ''WebAnimation/StrongBadEmail'' "email thunder", where the Poopsmith breaks his vow of silence to perform an email song for [[MilestoneCelebration the 200th episode]], and is voiced by John Linnell of Music/TheyMightBeGiants.
* The band of [[http://en.wikipedia.org/wiki/Infinite_%28band%29 Infinite]] appearing in ''Webcomic/WelcomeToTheConvenienceStore''.
* ''WebVideo/MovieFights'' occasionally brings in fan-requested Youtubers (such as Creator/DougWalker and Creator/ChrisStuckmann) as their "gladiators". The show has even brought in celebrities such as Creator/ElijahWood, Creator/MaxLandis and Creator/KevinSmith (the latter have actually appeared ''twice'' to fight in the shows).
* ''Machinima/RedVsBlue'': "Grey vs. Gray" stars (and was partially written by) the ''WebVideo/GameGrumps''. Arin Hanson, Suzy Hanson, Ross O'Donovan, and Barry Kramer provide the voices for Cobb, Reg, Deuce, and Squatch, while Barry and Brain Wecht helped write.
* ''Podcast/TopDownPerspective'': More are promised to be in the podcast, but so far the following people have been a guest, in order:
**Paul aka Exfauxure, before he become a permanent host, after Nathan decided to bow out from the podcast for various reasons.
**The guy who directs the HotPepperGameReviews channel.
**Nathan aka Kraznor when he decided to pop in once after stepping down as a co-host.
**Hank, a speedrunner, who regularly co-hosts with Paul on thier own podcast, Burning Barrel, when Sean was away in Europe.
* In-universe in ''Podcast/TheOrbitingHumanCircusOfTheAir'' the eponymous fictional radio VarietyShow has "Guest vocalist Romica, the extraordinary singing saw!" Romica appears to be the Circus' blatant in-show [[ProductPlacement promotion]] of its sponsor, Samuel Saws, who are reaping the benefits of the Circus' popularity.
* WebVideo/OnCinema has people involved in film having guest appearances as themselves during the series such as Joe Estevez, John Aprea and Payton Reed. Gregg is often billed as a guest despite appearing in just about as many episodes as Tim and serves more as a co-host.
* In ''Toys/TheGrosseryGang'' webseries' 2016 Christmas episode, special voice appearances by various toy reviewers that have reviewed the toyline are featured, including [=CookieSwirlC=], [=DisneyCarToys=], [=PSToyReviews=] and Chad Alan. [=CookieSwirlC=] returned in the 2017 Christmas special as a guest role, voicing [=PukieHurlC=], a parody of her mascot.

[[folder:Western Animation]]
* Both ''WesternAnimation/TheSimpsons'' and ''WesternAnimation/{{Futurama}}'' use this all the time, with "stars" as diverse as Creator/WilliamShatner, Creator/StephenHawking, Music/StephenSondheim, the Music/BackstreetBoys, and Creator/GaryGygax. As well as Al Gore and UsefulNotes/TonyBlair. ''The Simpsons'' even got ReclusiveArtist Creator/ThomasPynchon, which was the only time his voice has been broadcasted in the media.
** This has resulted in some bizarre incongruities when the guest stars have been celebrities with big lips, as the [[RubberForeheadAliens yellow-skinned humanoids]] on the show are famously lipless. Creator/KimBasinger kept hers, but [[Music/{{Aerosmith}} Steven Tyler]] voiced a version of himself with his conspicuously missing, resulting in [[UncannyValley what looked disturbingly like Steven Tyler as a reanimated corpse]].
** Invoked in one episode, where the Simpsons had a variety show similar to the one done by Series/TheBradyBunch in the late 1970s. Homer hides on one side of the stage, prompting this exchange:
-->'''Homer:''' I'm hi-i-iding from the gho-o-ost!
-->'''Marge:''' What ghost?
-->'''Homer:''' You said we were having a special ghost this evening!
-->'''Marge:''' I said we were having a special ''guest'' this evening - Mr. [[Series/TheCarolBurnettShow Tim Conway]]!
* The practice is mocked by ''WesternAnimation/SouthPark''. As the opening disclaimer notes, "All celebrity voices are impersonated... poorly." Parker and Stone are generally unwilling to allow celebrities to do guest spots on the show, and have avoided them since the very early seasons.
** George Clooney provided the dog noises for Stan's gay dog in the episode "Big Gay Al's Big Gay Boat Ride", and Jay Leno supplied the cat noises for Cartman's cat. Jerry Seinfeld contacted the show offering to do a guest spot, but his agent rejected the offer of performing as a turkey.
** Parker and Stone have gone on record saying that they have only ever requested two celebrities to perform on their show: Robert Smith and Natasha Henstridge. In contrast to the other guest spots, their roles actually come with a few lines, though Henstridge is billed as "That Chick from ''Film/{{Species}}''."
* A few episodes of ''WesternAnimation/SpongebobSquarepants'' include a special guest, who ends up being very minor. For example, one episode gives guest credit to someone who pops up as a surfer we see Pearl and her friends meeting for all of 10 seconds.
** Exception: Creator/PatMorita played the villain in one episode. This was one of his last performances before his death, and the episode was dedicated to him.
* The [[ActorExistenceFailure late]] Dan Wheldon, two-time winner of the Indy 500, voiced himself on the ''WesternAnimation/HotWheelsBattleForce5'' episode "Full Throttle".
* ''WesternAnimation/StaticShock'' had a number of these in the third season.
* This was basically the whole idea behind ''WesternAnimation/TheNewScoobyDooMovies''. Some of the guests, like Creator/DickVanDyke, Creator/SandyDuncan, and Sonny and Cher, played themselves; others, like Laurel and Hardy, [[CaptainObvious didn't]].
* ''WesternAnimation/TransformersAnimated'' had quite a few as well, such as Music/WeirdAlYankovic in the episode that introduced Wreck-Gar (a ShoutOut to the movie).
** Also George Takei as the cyberninja Master Yoketron.
* Speaking of Music/WeirdAlYankovic, he was in ''WesternAnimation/BatmanTheBraveAndTheBold'' in an episode where Batman and Robin team up with Franchise/ScoobyDoo and Shaggy to fight against a couple of Batman rogues.
* An episode of ''WesternAnimation/{{Arthur}}'' has [[Series/MisterRogersNeighborhood Mr. Fred Rogers]] make an animated appearance. Another episode had an appearance by Creator/NeilGaiman, who played a famous writer in-universe.
* ''WesternAnimation/TheFlintstones'', strangely, has Stone Age versions of Darrin and Samantha Stephens (voiced by guest stars Creator/DickYork and Creator/ElizabethMontgomery) moving in next door to Fred and Wilma.[[note]]Both ''The Flintstones'' and ''Series/{{Bewitched}}'' aired on ABC, and the former was distributed at the time by Screen Gems, which produced the latter.[[/note]] So... Samantha really ''is'' immortal, having lived from at least the Stone Age into the early 1970s.
** Another episode had them befriending famous actress "Ann-Margrock," voiced by movie star Ann-Margret.
* In the 1980s version of ''WesternAnimation/AlvinAndTheChipmunks'', the episode "Urban Chipmunk" has the guest voice of Music/DollyParton.
** Creator/MrT also appeared on an episode, voicing himself.
* The ''WesternAnimation/RockosModernLife'' episode "No Pain, No Gain" features RichardSimmons [[InksuitActor as an aerobics instructor]] at the high-end health club Rocko and Heffer are trying to join.
* In the "My Punky Valentine" episode of ''WesternAnimation/TheWeekenders'', one of the gambits Tino's friends use to get him to forget about a punky girl involves introducing him to Creator/JenniferLoveHewitt. It doesn't work, but it does result in being one of the few episodes which ''doesn't'' end with Tino saying, [[CatchPhrase "Later days!"]] - the Series/GhostWhisperer does it instead ("Hahaha!!! I feel like such a dork...").
* While ''WesternAnimation/CloneHigh'' had a couple of ActorAllusion characters, like Luke Perry; the most emphasized is Tom Green, who shows up ''as'' Tom Green to speak about [[AttentionDeficitOohShiny ADHD]].
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'': Music/WeirdAlYankovic guest-stars as Cheese Sandwich (who's basically a ponified version of Al himself), a friendly rival of Pinkie Pie who became a traveling party pony after she inspired him when they were both younger, in season 4.
** John de Lancie guest stars in the series whenever his character, Discord, is needed.
* ''WesternAnimation/DextersLaboratory'': The season 3 episode "Lab on the Run" had Fred Willard and Martin Mull from ''Series/FernwoodTonight'' as a pair of slacker robots, F.R.E.D. and MAR-10.
