[the Joker pins Batman, in view of the two rigged ferries]
The Joker: We really should stop fighting, we'll miss the fireworks!
Batman: There aren't going to be any fireworks!
The Joker: And here... we... go!
[Silence. Nothing happens. Confused, Joker turns to look at the clock, which shows that it's past midnight and neither of the ferries have blown the other up]
Batman: What were you hoping to prove? That, deep down, everyone's as ugly as you? You're *alone*!
The Joker: [sighs] Can't rely on anyone these days...
Batman: You'll be in a padded cell forever.
The Joker: Maybe we can 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.
The 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?
The Joker: I took Gotham's white knight and I brought him down to our level. It wasn't hard. You see, madness, as you know, is like gravity. All it takes is a little push!
[holds up his coin]
Two-Face: Unbiased. Unprejudiced. Fair.
Lt. James Gordon: No, you can't! You're not!
Batman: I'm whatever Gotham needs me to be.
The Joker: [laughs] I don't want to kill you! What would I do without you? Go back to ripping off mob dealers? No, no, NO! No. You... you... complete me.
Batman: You're garbage who kills for money.
The Joker: Don'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 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.
James Gordon Jr.: Why's he running, Dad?
Lt. James Gordon: Because we have to chase him.
James Gordon Jr.: He didn't do anything wrong.
Lt. James Gordon: Because he's the hero Gotham deserves, but not the one it needs right now. So we'll hunt him because he can take it. Because he's not our hero. He's a silent guardian, a watchful protector. A dark knight.
