Christopher NolanDon't talk like one of them. You're not! Even if you'd like to be. To them, you're just a freak, like me!

They're only as good as the world allows them to be. I'll show you. When the chips are down, these... these civilized people, they'll eat each other. See, I'm not a monster. I'm just ahead of the curve. -The Joker
