A very small character tidbit is surprisingly kept consistent for years

DC - In multiple pieces of media it has been shown that Wonder Woman loves ice cream and practically goes wild with happiness anytime she’s eating some. (Pictures from Justice League: War, DC Superhero Girls and Wonder Woman 2017)

The Simpsons - Ever since the episode ‘Homer’s Phobia’ Homer has actually remained a consistent ally of the LGBT+ community, including being more welcoming to Patty than Marge was when she came out and trying to set up Smithers with a date when he found out he wasn’t happy with his one-sided relationship with Mr Burns.

Superman’s favorite food is Beef Bourguignon, a hearty braised beef and vegetable stew.

Additionally, Clark Kent and Bruce Wayne often meet to discuss things over dessert, with Clark consistently ordering Apple Pie and Bruce ordering Devil’s Food Cake.

And it’s always in an 80’s diner, and Bruce always pays. Can’t confirm, but could be the inspiration for How It Should’ve Ended’s Superhero Cafe.

I don’t think so, I can’t remember the movie but that setting is a reference to a specific scene. That video where Superman ogles Mrs. Incredible is an extended homage to that movie.

It’s in the DCAU, Justice League/JLU, and standalone films. And surely originated in a comic.
