The best lines from the Dark Knight

Dunno why these lines kept ringing in my head recently...

The Joker to Batman

To them, you're just a freak, like me! They need you right now, but when they don't, they'll cast you out, like a leper! You see, their morals, their code, it's a bad joke. Dropped at the first sign of trouble. 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.

or this one

The Joker: Do you want to know why I use a knife? Guns are too quick. You can't savor all the... little emotions. In... you see, in their last moments, people show you who they really are. So in a way, I know your friends better than you ever did. Would you like to know which of them were cowards?

And I do have a little collection like the Joker...
