Batman: What were you trying to prove? That deep down, everyone's as ugly as you? You're alone.
Joker: Can't rely on anyone these days. You gotta do everything yourself. Don't we? That's okay. I came prepared. It's a funny world we live in. Speaking of which, you know how I got these scars?
Batman: No, but I know how you got these.
Joker: Oh, you. You just couldn't let me go, could you? This is what happens when an unstoppable force...meets an immovable object. You truly are incorruptible, aren't you? Huh? You won't kill me...out of some misplaced sense of self-righteousness. And I won't kill you...because you're just too much fun. I think you and I are destined to do this forever.
Batman: You'll be in a padded cell forever.
Joker: Maybe we could share one. You know, they'll be doubling up...the rate this city's inhabitants are losing their minds.
Batman: This city just showed you...that it's full of people ready to believe in good.
Joker: Until their spirit breaks completely. Until they get a good look at the real Harvey Dent...and all the heroic things he's done. You didn't think I'd risk losing the battle for Gotham's soul...in a fistfight with you? No. You need an ace in the hole. Mine's Harvey.
Batman: What did you do?
Joker: I took Gotham's white knight...and I brought him down to our level. It wasn't hard. See, madness, as you know...is like gravity. All it takes is a little push.
