Here's an interesting trope from TV tropes. It is as it says. There are some things that are just too crazy, insane, weird, or wild to make you think that people involved in the projects weren't high on something. This can apply to basically any media from movies, TV shows, to even video games.
Here's a link to the page:

I nominate 3 movies right off the bat for this since they are just too out there. Cool World, Monkeybone, and Raggedy Ann and Andy: A Musical Adventure. Those 3 are just insane and crazy. A scene of a movie I would think of is the Helfalump scene from Winne the Pooh. A video game that would work for this is Psychonauts.
