The Joker: I believe whatever doesn't kill you, simply makes you... Stranger.
The Joker: Introduce a little anarchy. Upset the established order and everything becomes chaos. I'm an agent of chaos. Oh, and you know what the thing about chaos is? It's fair.
Alfred Pennyworth: So I suppose they'll be arresting me for being your accomplice, sir.
Bruce Wayne: Accomplice?I'm gonna tell them the whole thing was your idea.
Gambol: You think you can steal from us and get away with it?
The Joker: Yeah.
The Joker: Madness is like gravity... All you need is a little push.
The Joker: Why so serious?
Party guest: We're not intimidated by thugs.
Joker: You know, you remind me of my father. I hated my father.
The Joker: You won't kill me out of some mis-placed sense of self-righteousness. And I won't kill you because you're just too much fun.
The Joker: If you are good at something, never do it for free.
Harvey Dent: The night is darkest just before the dawn. And I promise you the dawn is coming.
Alfred Pennyworth: Know your limits, Master Wayne.
Bruce Wayne: Batman has no limits.
Gambol: You're crazy.
The Joker: I'm not. No, I'm not.
[To the group of mobsters.]
The Joker: This suit wasn't cheap. You ought to know; you bought it.
The Joker: You see, it's all part of the plan.
Harvey Dent: What was that name you all had for me down at the D.A.'s office? Say it. SAY IT!
Commissioner Gordon: Two Face, Harvey Two Face. (01:02:20)
The Joker: Wanna know how I got these scars?
Answer: The gun fires using compressed carbon dioxide as a propellant. The cable is wrapped in a coil around a motorized turbine within the gun. The pulley system in Batman's belt buckle allows him to reel himself in hands-free and still maintain equilibrium. There is a four-pronged grapple at the end of the cable. This is what is magnetized, creating an attraction between it and the monofilament cable. This ensures that the grapple will attach itself to the cable for a secure hold. This is why the magnet itself does not need to be especially strong to support any amount of weight. It also explains the relative ease with which it can be detached and its seemingly "magical" ability to wrap itself around various objects.
