Vicki Vale: Some people think you're as dangerous as the Joker.
Batman: He's psychotic.
Vicki Vale: Some people say the same about you.
Batman: What people?
Vicki Vale: Well, face it. You're not exactly normal, are you?
Batman: This isn't exactly a normal world, is it?
Vicki Vale: I've just got to know. Are we gonna try and love each other?
Bruce Wayne: I'd like to. But he's out there right now. And I've got to go to work.
Vicki Vale: [distracting Joker] Mr. Joker, you make such beautiful things... oh, you're so powerful, and... PURPLE! Oh, I love purple.
Batman: Excuse me.
Batman: Have you ever danced with the devil by the pale moon light?
The Joker: I recently had a tragedy in my life. Alicia...
[lays the mask that Alicia wore on the table]
The Joker: ... threw herself out the window.
Vicki Vale: Oh, my God...
The Joker: But, you can't make an omelette without breaking some eggs.
[breaks the mask and starts giggling]
Grissom: Your life won't be worth spit!
The Joker: I've been dead once already, its very liberating. You should think of it as therapy.
Grissom: Jack, maybe we can cut a deal.
The Joker: Jack?
The Joker: Jack is dead, my friend. You can call me Joker and as you can see I'm a lot happier.
Haven't you ever heard of the healing power of laughter?The Joker
