I admit that I am not super familiar with the comics. Most of my superhero knowledge comes from movies, cartoons, and video games. There is one thing I've noticed, though, that I was wondering about. Why is Joker always falling off of buildings? In Michael Keaton's Batman movie, Joker falls off a building to his death, and we hear him laughing. In The Dark Knight, Joker falls off a building, and it would have been to his death had Batman not saved him. I've been playing the new game Arkham Origins, and there's a scene where Joker falls off a building, and once again Batman saves him. It seems to be a recurring theme, and I was wondering if all of these scenes were paying an homage to something from the comics.
