10 Straight Up Craziest Things The Joker Has Ever Done

10. Joker Fish

Warner Bros. Television Distribution

Originally being a story from the Golden Age of comics, the Laughing Fish would eventually come to be adopted by the seminal Batman: The Animated Series, bringing this hilarious story to the mainstream, modern audience.

In the story of the Laughing Fish, Joker poisons the fish in Gotham’s water so that they look like him, complete with pale ‘skin’ and a big, unnerving smile. The fish themselves weren’t harmful to humans; instead, the purpose of Joker’s plan was to trademark the fish so that he could make a profit from his image.

This is another classic Joker story whereby the Clown Prince of Crime simply wants to get his likeness out into the public domain (and profit off of it of course).

However, the Gotham patent office wouldn’t allow the Joker to copyright his fish, so he started to attack officers from the patent office in an effort to force through his copyright claim. Naturally, though, this plan doesn't work out.
