Grissom: That you, sugar bumps?
[turns around to see a man]
Grissom: Who the hell are you?
Joker: It's me, Sugar bumps.
Grissom: Jack? Oh, oh, thank God you're alive! I heard you'd been...
Joker: Fried? Is that what you heard? You set me up over a woman. A *woman*! You must be insane.
[Grissom goes for his gun]
Joker: Don't bother.
Grissom: Your life won't be worth spit!
Joker: I've been dead once already. It's very liberating. You should think of it as, uh... therapy.
Grissom: Jack, listen. Maybe we can cut a deal.
Joker: Jack? Jack is dead, my friend.
[steps into the light]
Joker: You can call me... Joker. And as you can see, I'm a lot happier.
[laughs, and then proceeds to kill Grissom]
