"We found out early that if you did something with a character, either animal or human or whatnot, that couldn't possibly be rigged up in live action, why then, you've got a guaranteed laugh. If a human can do it, a lot of times it isn't funny in animation. Or even if it is funny, a human could do it funnier....But if you can take a fellow and have him get hit on the head and then he cracks up like a piece of china, then you know you've got a laugh!"
—Tex Avery, in an interview with Joe Adamson.
Maybe I'm just a duck, but I'm human.
