* The arcade version of ''DoubleDragon'' features the red sports car from Data East's FMV game ''Road Blaster'' (a.k.a. ''Road Avenger'') inside Billy and Jimmy's garage, as well as a billboard advertising ''[[KunioKun Nekketsu Koha Kunio-kun]]'' (the Japanese version of ''Renegade'') just before the first boss battle. Both were games previously directed by Yoshihisa Kishimoto, the director of ''Double Dragon''. In the arcade version of ''Double Dragon II'', the helicopter from ''Cobra Command'' (Kishimoto's other FMV game he did for Data East) appears in the garage at the beginning as well.

* George Lucas films reuse the number 1138, after his debut feature, ''Film/{{THX 1138}}'' (which was itself derived from his phone number when he made the original student film version).

* [[http://en.wikipedia.org/wiki/Vermicious_Knid Vermicious Knids]], which originate from ''CharlieAndTheGreatGlassElevator'', get passing mentions as monsters in a handful of other RoaldDahl books.

** It's also used to access {{Easter Egg}}s on the ''StarWars'' {{DVD}}s (push the buttons on your remote from the menu where you highlight the "THX" calibration logo).
** This is also a common number to be used as an {{homage}} (sometimes in credit to IndustrialLightAndMagic and the other Lucas production companies):

* In ''{{Community}}'' episode [[Recap/CommunityS1E13InvestigativeJournalism Investigative Journalism]] Jack Black played a character named "Buddy Austen", who shares a last name with Jack Austen, the main character in the TV pilot HeatVisionAndJack (created by Dan Harmon) also played by Jack Black. Also, [[spoiler:Owen Wilson, who voiced Heat Vision]], made a cameo appearance in the same episode.

* HideoKojima has a habit of inserting references to his previous works in his newer works, beginning with ''{{Snatcher}}'', which included references to the original ''VideoGame/MetalGear'' (such as Gillian's robotic companion modeled after the Metal Gear mecha), and then with ''MetalGear2'' (which referenced the Snatcher Project and canonized Dr. Pettrovich's surname as "Madnar"), ''{{Policenauts}}'' (which included plenty of ''Metal Gear'' and ''Snatcher'' references), and the ''TokimekiMemorial Drama Series'' (which included several ''Policenauts'' and ''Metal Gear Solid'' references). The most popular example is the {{transplant}} of Meryl Silverburgh, originally a ''Policenauts'' character, into ''MetalGearSolid''.

** Akamatsu also confirmed that Nitta-sensei is the same Nitta-sensei from his first series, AILoveYou. Not to mention that Negima's BigBad Fate Averruncus is a rather obvious expy of Program Number 0.

* ''MahouSenseiNegima'' is full of ShoutOuts to KenAkamatsu's previous series, ''LoveHina''. Outside the numerous {{Expy}}s, Tama the turtle has a cameo, the famous [[MegatonPunch "Naru Punch"]] makes a reappearance, and one of Motoko's sword techniques sees some use in ''Negima''. In addition, several characters from LoveHina make reappearances in ''Negima''. The creator also [[WordOfGod confirmed]] that the hotel at which the characters stay in (one of) Negima's {{Beach Episode}}s is the same one where Naru and Keitaro stayed.

* Composer Mark Knopfler said that he would write the music for ''ThePrincessBride'' only if Rob Reiner worked the hat he wore as Marty [=DiBergi=] in ''ThisIsSpinalTap'' into it. Although he couldn't get the exact same hat, a similar one appears among FredSavage's things around the head of his bed. (Knopfler later replied he was joking about the refusal to work on the film.)

* MostTriumphantExample: {{Machete}}, star of his own ([[{{Defictionalization}} no longer fictional]]) movie, shares the name, actor, and occupational field of a character from RobertRodriguez's ''SpyKids'' and [[InNameOnly nothing else]].

* Before creating KingdomOfLoathing, Team Asymmetric created a game called Krakox the Barbarian. At least one item from that game appears in Kol, the Ring of Half-Assed Regeneration.

* {{Pixar}} does this in [[http://jimhillmedia.com/blogs/jim_hill/archive/2007/12/09/a-special-where-s-wall-e-edition-of-why-for.aspx most, if not all, of its feature films]], usually with characters from its shorts:
** The lamp from Pixar's (canonically) "first" short, ''Luxo Jr.'' crushes the ''i'' in "Pixar" in the studio's standard VanityPlate.
** The ball from the same short likewise appears in pretty much every movie they ever make.
** Similarly, the Pizza Planet delivery van in every film since ''ToyStory''.
** The old man Geri from "Geri's Game" reappears as a toy repair man in ''ToyStory2''.
* In ''TheSimpsons'', characters from Matt Groening's ''LifeInHell'' comic strip (usually Bongo) sometimes appear as stuffed toys.
** In the early 1990s ''Simpsons'' arcade game, they appeared as enemies in the DreamLand level (as well as every interstitial title screen).
** In ''{{Futurama}}'', Bongo appears in a pet shop.

* ''MahouSenseiNegima'' is full of ShoutOuts to KenAkamatsu's previous series, ''LoveHina''. Outside the numerous {{Expy}}s, Tama the turtle has a cameo, the famous [[MegatonPunch "Naru Punch"]] makes a reappearance, and one of Motoko's sword techniques sees some use in ''Negima''.

* Any appearance of JohnMunch.
* Telltale's first game, ''Telltale Texas Hold'Em'' featured a mustached character named "Boris Krinkle", in which one possible line of dialogue has the character of Grandma telling him that he looks more like a 'Leonard Steakcharmer'." Naturally, when you first meet Leonard, sans mustache, in Telltale's SamAndMax episode ''The Mole, The Mob, and The Meatball'', you get the option to say he looks more like a Boris Krinkle.

* MSPaintAdventures has jokes from earlier adventures in the same series as well as [[MythologyGag unrelated old webcomics by the same author]]. Thus, in ''{{Homestuck}}'', you have allusions to pumpkins disappearing and retrieval of arms from the author's first experimentings with the format.
* {{Sintel}} features characters from the Blender Foundations two previous shorts. In the market scene, you can clearly see Proog from ''ElephantsDream'', and the butterflies in the bamboo forest are just a ''PaletteSwap'' of the ones from ''BigBuckBunny''.
