The lines of the clown when he blew up the boat in The Dark Knight

Joker: We really should stop this fight, or we will miss the fireworks.

Joker: We really should stop fighting, or we will miss the fireworks. )

Batman: There won't be any fireworks!

Batman: There won't be any fireworks! )

Joker: Here ~ Let's go ~

(Joker: Go ~ Go ~ La ~)

Nothing happened, the citizens didn't detonate the bomb, and the clown tried to laugh but didn't.

Batman: What are you trying to prove? Everyone is as ugly as you deep down? You are lonely!

Batman: What are you trying to prove? Prove that everyone is as ugly as you deep down? You have no one of your kind! )

Joker: No one can rely on these days. You have to do everything yourself, don't you? ! It's okay. I came prepared. We live in an interesting world. Speaking of which, do you know how I got these scars?

Joker: Nobody can be trusted these days. Do everything yourself, don't you think! It's okay. I have two things to prepare. The world is absurd. On the other hand, do you know where my scar came from? )

Batman: No, but I know how you got these!

Batman: I don't know, but I know how these came from! )

Batman shot the weapon hidden in his arm at the clown's face.
