You know how videogames have these stale repetitive jokes that have been told for years and people still mention them somehow? Like "lol, Mario is on drugs because mushrooms and you must be high to imagine stepping on turtles!", or "Pokemon is videogame cockfighting! Lol!". What would be the equivalent in anime, in your personal opinion? Stale jokes that are still thrown, even in this site? Mention also older stale jokes that you were tired off even back then, either from the fanbase itself or from normalfags, from a particular series and particular fandom, or even the ones that have made it into the media itself.
I'll start with the obvious
>lol, tentacles in anime!
>Oh Japan, you're so wacky!
Whenever something slightly different happens
Though the FBI jokes and RAVIOLI RAVIOLI take the goddamn cake nowadays.
