Selina Kyle: You've got to admit there's something between us.

Batman: Yes. It's the law.

The Joker: [after Batman fights back against his hyenas] Hey! Do I hit your kids? Oh, actually I do...

Batman: Last time we met, you tried to throw me off a building.

The Joker: I did?

[laughs]

The Joker: That was so long ago!

Batman: That was last month.
