A Mythology Gag is a reference to past iterations of a work that are explicitly not Canon to the work in question. A meta-Continuity Nod, if you will. Often seen in Reboots or Series Franchises when an element from the previous version is referenced or seen in some way, usually as an acknowledgment to fans of earlier incarnations. When successful, it serves as a reassurance to those fans that the producers aren't trying to disrespect the original source material. When unsuccessful, it only reminds fans that the original source material essentially never happened.
This trope is usually taken largely as a bit of gratuitous humor, since if the program you're watching is "real" then the characters shouldn't be thinking in terms of any continuity, alternate or otherwise. Sometimes this will be lampshaded by the characters, who wonder how they could possibly know such a thing. Also, the Celebrity Paradox might come into play.
See Remake Cameo for when the Mythology Gag involves actors from the original production. Compare Continuity Nod, Discontinuity Nod, Recurring Element, I Want You to Meet an Old Friend of Mine, Actor Allusion, Continuity Cameo, Company Cross References, Ascended Meme, Meet Your Early-Installment Weirdness (when taken a step further) and Shout-Out. Contrast Development Gag, which references things that would have been part of the work but were left out halfway through production, and Early-Bird Cameo.
Remember, it's only this if the events happened in a different continuity. Otherwise, it's a Continuity Nod or a Call-Back.

Other examples:
- The Sistine Chapel, the physical building itself, has the same dimensions (40.9 meters long by 13.4 meters wide) as the Temple of Solomon does in The Bible. This reinforces one of the main theses of the Chapel: to demonstrate that the Christian tradition flows directly from the teachings of Judaism.
- The Animated Adaptation (and its non-canon chibi Spin-Off) of Grandmaster of Demonic Cultivation: Mo Dao Zu Shi often references novel events that aren't present in the adaptation.
- Wei Wuxian flips through his old notebook that Lan Wangji kept and briefly pauses to admire his flower bookmark. This is a reference to the flower bookmark Lan Wangji uses in the novel, which is hinted to be given to him by Wei Wuxian from one of the multiple instances he threw flowers at him.
- In the final episode, the protagonists return to a cottage in the mountains that's implied to be a home they live in outside of Gusu. In the novel, Wei Wuxian mentions multiple times his dream of retiring in a house in a secluded area to live a rural life with Lan Wangji.
- One episode of the spinoff has Lan Wangji and Lan Xichen trying out Wei Wuxian's food "suggestions" (such as eating lotus seeds from a lotus pod that has its stem intact). This references the novel extra chapter "Lotus Seed Pod", where Lan Wangji asked his brother about the food suggestions during their training session and later looked for fresh lotus pods so he could try them out.
- The chibi Spin-Off twice brings back the Heavenly Maiden statue (a troublesome Arc Villain the cast has to defeat early in the main story) just to have characters comically beat it up.
- Statius begins The Achilleid by praying to Apollo to give him more inspiration after using it all up of writing about Thebes, referencing the first epic he wrote.
- The RiffTrax for Batman & Robin contains a joke pointing out the resemblance between Dr. Woodrue and a certain character from Rifftrax's spiritual predecessor...
Bill Corbett: (as Woodrue) Yes! Now to achieve my lifelong dream of launching a man into space and forcing him to watch really bad movies!
- The Rifftrax for the first X-Men movie has a Call-Back to a joke from Mystery Science Theater 3000.
Mike Nelson: She wandered into Thunderdome!
Bill Corbet: Mike...
Mike Nelson: (realizing) Oh. Oh no...
Bill Corbet: Mike... can't we get beyond 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 Star Wars: Episode IV: A New Hope has a throwback to a Running Gag on the Mystery Science Theater 3000 episode Space Mutiny, 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 Revenge of the Sith:
- Bill also comments on X-Men's setting of "The Not-Too-Distant Future".
Bill: Huh, that seems familiar...
- In D-War, a deep voiced villain asks for help. Leading to "Zap Rowsdower, is that you?"
- The Rifftrax for the first X-Men movie has a Call-Back to a joke from Mystery Science Theater 3000.
- Albeit briefly, Animated Inanimate Battle pulled one off in the show's intro. As a nod to its pilot episode, Brain and Bouncy Ball can be seen playing poker, with the same Early-Installment Weirdness that can be seen in the pilot.
- In Black Rhino Ranger's animated music video, "Now That's What I Call Skylanders Polka", when Kaos sings "Only got twenty dollars in my pocket", Terrafin appears in the corner and shouts "THAT'S HOW MUCH HE OWES ME!", referencing a commercial for Skylanders: Spyro's Adventure where Terrafin claims Kaos owes him money.
- Minilife TV: The show Ian watches on the TV in the episode "Starsaber Duel" is Terry Serpent's Swimming Spectacle from Chris Salaises' old YouTube channel, chris14S.

- Viktor angrily retorts he has a 'very good idea' of what Rocky went through to get his alcohol, referencing his past in the comic working for Lackadaisy as a rum-runner.
- During his Rummage Fail, Rocky tosses aside the cactus he gifted Mitzi in a non-canon side strip
