* BigLippedAlligatorMoment:
** A few of Stan Lee's cameos, such in ''Star Trek'' where he's [[spoiler:teleported into the transporter room, dressed in a tuxedo and singing "Hello, My Baby!"]], or in the second ''Iron Man'' episode, where he's [[spoiler:sitting on a tiny planet in outer space]].
** Captain America somehow pulls out and blows a conch shell when Bruce Banner [[HulkingOut Hulks out]] in the bowling alley.
* EarWorm: The music that plays during the opening credits will become infectious the more frequently you watch, especially since cartoons from season two onward play it at both the beginning and the end.
* HilariousInHindsight:
** After the release of ''Film/IronMan3'', it seems ironic that Iron Man's second episode [[spoiler:makes the Mandarin resemble Creator/BenKingsley.]]
** One of the characters who cameoed in the ''Guardians of the Galaxy'' short makes an appearance in TheStinger of the ''Film/GuardiansOfTheGalaxy'' movie...[[spoiler:ComicBook/HowardTheDuck. In the commentary (also released before the movie), Junaid explains Howard's ''Bad Days'' cameo with simply, "...because he's weird."]] The ''Bad Days'' crew also correctly predicted a cameo by some ''Film/{{Slither}}'' slugs.
* NauseaFuel: The {{Vomit Indiscretion Shot}}s.
* {{Squick}}:
** Wolverine's attempt to eat sushi off of his blades causes him to slice his face open. [[GoodThingYouCanHeal Good thing he can heal]].
** In ''Ant-Man'', [[spoiler:TheReveal that the female ant had sex with an unconscious Ant-Man.]]
* TakeThatScrappy: SelfDemonstrating/{{Magneto}} shooing away ComicBook/{{Quicksilver}} in the ''Days of Future Past'' spoof was supposed to be this, although Quicksilver becoming an EnsembleDarkhorse after the movie's premiere might have ruined the joke.
* TheWoobie: Most of the superheroes, but Bruce Banner especially. His episode might as well be titled ''Bad Life''.
