*** Really, the only way it makes sense at this point is to just [[WildMassGuessing theorise]] that ''Cougar Town'' exists all within [[AdventureInComaland Ted's mind]], haivng finally jumped off of the roof when Gooch left him for Hooch.

** [=McGee=] is obviously a fan of ''Series/DoctorWho'', since he mentions the TARDIS in one episode. Yet when he meets Gibbs' CI Miranda Pennebaker (played by AlexKingston) in the tenth season, he doesn't notice that she looks exactly like River Song.

* On ''Series/DiagnosisMurder'', Amanda Bentley has a Contest Winner Cameo on 'Young and the Restless' and both her colleagues at the hospital and the crew of [=YatR=] comment on her resemblance to Victoria Rowell, who actually was a regular cast member of that series.

*** There's an even more explicit overlap in the form of "Dimensions in Time", a CrossoverEpisode of ''DoctorWho'' and ''EastEnders'', which aired between the end of "old" Who and TheMovie. In addition to "Army of Ghosts", the episode "Night Terrors" has Fory comparing the location to ''Eastenders''.

* Apparently, the American version of ''LifeOnMars'' is [[spoiler:an astronaut going to Mars, thinking of the song "Life on Mars," picturing himself in an American version of ''LifeOnMars'']]. OrWasItADream? (Yeah.)

** Also, the guy who played the aforementioned delusional is Clint Howard (brother of {{Ron|Howard}}), who appeared in the episodes "[[Series/StarTrekTheOriginalSeries The Corbomite Maneuver]]", "[[Series/StarTrekDeepSpaceNine Past Tense, Part II]]", and "[[Series/StarTrekEnterprise Acquisition]]".

** An episode of ''The Sopranos'' has a character watching ''Series/CurbYourEnthusiasm''. Conversely, characters on ''Curb'' have mentioned ''Sopranos'' and HBO.

** In one episode in season 1, the characters have a discussion about how Mayim Bialik and Danica [=McKellar=] are serious academics as well as actresses. It would've been weird enough if just one of them had shown up later in the series, but ''both'' actresses would end up playing fictional guest parts in season 3.
*** Bialik has since become a series regular, playing Sheldon's [[SheIsNotMyGirlfriend friend who is a girl]].
*** Raj also mentions "the girl who played TV's Blossoms" and suggesting she join their Physics Bowl team.

* In a first-season episode of ''DueSouth'', Constable Fraser (Paul Gross) mentions that Constable Buck Frobisher bears a striking resemblance to "noted Canadian character actor LeslieNielsen. Frobisher is played by Nielsen.

* ''TheCatherineTateShow'' did a sketch for ComicRelief which featured DavidTennant as Lauren Cooper's teacher. She frequently jokes throughout the sketch about how much he resembles [[Series/DoctorWho the Doctor]] ("Your house...is it BiggerOnTheInside?" "D'you fancy Music/BilliePiper, sir?"). At the end, he zaps her with the Tissue Compression Eliminator, turning her into a Rose Tyler action figure.

* Although it's not explicitly stated, ''Series/TheWalkingDead'' seems to lack the entire history of zombie fiction. In season two Glen offhandedly mentions that he used to play ''VideoGame/Portal'' which suggests that in the world of Walking Dead Valve exists, but the Left4Dead series does not.

** Likewise, ''BuffyTheVampireSlayer'' has been mentioned on the show, yet despite the fact that several of its actors and actresses such as JamesMarsters, Charisma Carpenter, Harry Groener, Mercedes [=McNab=], AmberBenson, Julie Benz, or FeliciaDay have guest-starred on it, absolute no one has come up to any of their respective characters and commented on the fact that they look familiar.

** There is also an example involving not an actor, but a writer. In [[Recap/DoctorWho2005CSTheChristmasInvasion The Christmas Invasion]], the Doctor says something about saving the world in his pajamas and that it's "very [[TheHitchhikersGuideToTheGalaxy Arthur Dent]]". DouglasAdams, who wrote TheHitchhikersGuideToTheGalaxy, also wrote several episodes of the original Series/DoctorWho series.
