Depends what Joker you are talking about. I don't think hannibal can fuck with the new one, when he slammed that big dude's head through the pencil I thought to myself, "he would fuck up hannibal."
Would the joker beat Chuck Norris ? According the Chuck Norris facts that's impossible but after watching The Dark Knight several times I think that I changed my mind.
