So what true story was Coyote vs Acme based on?
I'm aware it doesn't need to be the exact story, to be ACTUALLY based on a true story.
However, movies and TV shows are under now obligation to fit that criteria just because they put it in a title card.
Another series that comes to mind is the Fargo TV series where the intro to each episode says it's based on a true story or whatever. And that show has aliens in it and shit. It's also explicitly not based on true stories, aliens or not. Putting it before every episode is a form of dark humor.
A quick Google suggests that the original Fargo movie was also not based on a true story.
