Alternate take of Batman and the Joker's first conversation in The Dark Knight.
*Okay this question's getting asked a lot so just to be clear: I play the Joker, and I play Batman. Same guy. I did everything except punch myself in the face, which came compliments of my friend Robert (I think you can see how much he enjoyed it). Thank you all for watching.
