I said this before in this thread, but having seen the movie a third time yesterday I just really have to say again that my favorite line belongs to Gordon, speaking to Maroni outside Dent's hospital room.
"You should have thought of that before you let the clown out of the box."
Pretty much describes the whole movie, right there.

Others:
Joker: "I want my phone call. I want it... I want it... I want my phone call."
Spoken just like a little kid. And the cop's response: "That's nice".
Joker: "You were a schemer. You had plans. And look how that turned out."
Joker: "Me?? I was right here. Who did you leave him with? One of your people? Or are they Maroni's?" I love how he turns it around and places the blame for Dent's disappearance on poor Gordon.
Joker: "Don't talk like you're one of them. You're not. Even if you'd like to be. You see to them, you're just a freak. Like me! They need you now, but one day... They'll cast you out. Like a leper." This is brilliant. One freak talking honestly to another. And you can feel how much Batman's anger is building because, deep down inside, he knows it's true.
Joker: "I'm like a dog chasing cars. I wouldn't know what to do if I caught one!" One of the brilliant things about Heath's performance was the way he changed his voice - not from one line to the next, but multiple times within the same line. The way he says "I wouldn't know what to do if I caught one!" is like insanity perfectly encapsulated.
Batman: "Surely he has friends?"
Maroni: "Friends? Have you met this guy?"
t:
Dent: "I guess no answer is a no. Is it someone else? Just tell me it's not Wayne, he's such a..."
I would love to have heard what he was going to call him!
