* The Podcast/RiffTrax for ''Film/BatmanAndRobin'' contains a joke pointing out the resemblance between Dr. Woodrue and a certain character from Rifftrax's [[SpiritualSuccessor spiritual predecessor]]...
-->'''Bill Corbett: (as Woodrue)''' Yes! Now to achieve my lifelong dream of [[Series/MysteryScienceTheater3000 launching a man into space and forcing him to watch really bad movies]]!
** The Rifftrax for the first ''Film/XMen1'' movie has a CallBack to a joke from ''Series/MysteryScienceTheater3000''.
--->'''Mike Nelson:''' She wandered into Thunderdome!\\
'''Bill Corbet:''' Mike...\\
'''Mike Nelson: (realizing)''' Oh. Oh no...\\
'''Bill Corbet:''' Mike... can't we get '''[[IncrediblyLamePun beyond]]''' [[IncrediblyLamePun Thunderdome]]?
*** Even funnier as the exchange being referenced was in one of the last sketches between Mike and Crow as played by Trace Beaulieu, not Bill Corbett.
** The Rifftrax for ''[[StarWars Star Wars: Episode IV: A New Hope]]'' has a throwback to a RunningGag on the ''Series/MysteryScienceTheater3000'' episode ''Film/SpaceMutiny,'' one of the most popular episodes.
--->'''Han Solo:''' Chewie! Get us outta here!!\\
'''Bill:''' Kalgan, take me away!
*** Not necessarily a throwback, because there is a real product (Calgon) with this slogan.
** Bill Corbett comments of Anakin and Palpatine in the theater in the Rifftrax for ''Film/RevengeOfTheSith'':
--->"[[HypocriticalHumor So, they're just gonna sit alone in those theater seats and make wisecracks about the show? What jerks!]]"
** Bill also comments on X-Men's setting of "The Not-Too-Distant Future".
--->'''Bill:''' [[ThemeTuneCameo Huh, that seems familiar]]...
** In D-War, a deep voiced villain asks for help. Leading to "[[Film/TheFinalSacrifice Zap Rowsdower, is that you?]]"
* In the October 2, 2008 [[StarWars HoloNet News broadcast]], when discussing the Separatists' [[WesternAnimation/StarWarsTheCloneWars new super weapon]], there was mention of how big a ship had to be to mount an ion cannon capable of wiping out entire task forces. The minimal values that the commentators suggest were 8, 12, and 17... which happen to be the different lengths Super Star Destroyers have had in various official media.
* ''WebAnimation/IfTheEmperorHadATextToSpeechDevice'' has some examples of one fan work referencing another:
** The Emperor mentions a card-games-and-chess parties the top {{Magnificent Bastard}}s of the 'verse[[note]]Namely, him, the Deceiver, Tzeentch, Cegorach and Creed[[/note]] have in the Webway. This is a joke from [[Website/FourChan /tg/]].
** At one point, Torquemada Coteaz from fan-film ''Film/TheLordInquisitor'' shows up, leds a hand to the antagonist and then returns to finish his film.
** In the second Q&A, one of the letters is from the Millennial, a character from fanfic ''[[https://www.fanfiction.net/s/11227059/1/Defrosted-A-40K-Story Defrosted]]''.
* In the current version of the webnovel ''{{John Dies at the End}}'', the protagonists are heading to a final showdown without really knowing what to expect, and the narrator is armed with a chainsaw. At one point, he wonders whether he could have gotten caught in his situation with a dumber weapon. This is a nod to the earliest version of the story, wherein the narrator is in the same situation, but armed with a sword.
* ''WebVideo/ThereWillBeBrawl'' is chock full of Mythology Gags from all over the Creator/{{Nintendo}} universe.
* In ''The Brothers Mario'' by The Game Station, has the eponymous characters knock over an armored truck with a million coins. They mention how it's enough to buy a new life. It's enough to buy [[LawOfOneHundred 10'000 new lives]].
* ''WebAnimation/LuckyDayForever'' has some visible influence from Alek's other animations, like the robots from "Smile", the strange attitude of "Polsupah", and 514's facial structure which is comparable to the poet from "Hanged Man's Elegy".
* ''WebVideo/JoJosBizarreAdventureAbridged'' contains a plethora of in-jokes from [[Manga/JoJosBizarreAdventure its source material]].
* ''Franchise/EverAfterHigh'' is chock full of gags inspired by the source materials.
* ''WebVideo/VaguelyRecallingJoJo''
** Before the recap of the 2nd part of the Rubber Soul mini-arc, Rudolf von Stroheim entered the Guile Look-a-Like contest and wins First Place, which is a reference to Guile being based on Stroheim.
** Sort of. Jotaro mistaking [[VideoGame/TheKingOfFighters Benimaru Nikaido]] for Polnareff is a reference to how Benimaru was explicitly based off of Polnareff (to the point that some of SNK's development team sometimes still call him Polnareff.)
* ''WebAnimation/BonusStage'' often made references to its predecessor series, ''WebAnimation/HighScore'', especially in earlier episodes. In one episode, Phil makes such a reference to an evil robot ex-girlfriend. Joel responds by laughing and then gruffly saying that they don't reference ''High Score'' anymore.
* ''WebAnimation/GEOWeasel'' makes references to its past as a comic, particularly as a {{sprite comic}}.
* ''Music/SiIvaGunner'', a channel made to pass off edited audios, remixes and arrangements of videogames songs as the real thing to unsuspecting viewers, does this with the channel it's based on (GilvaSunner). This happens on aspects from titling and thumbnails to even errors made in the original channel. For example, in GilvaSunner's rip of Mega Mushroom from New Super Mario Bros, [[https://www.youtube.com/watch?v=vwC8IarSch0 a voice clip from Luigi was left at the start by mistake]]. On [[https://www.youtube.com/watch?v=DuuZWHzOSQ0 this]] edit by SiIvaGunner, he replicates said error as a gag.
