Joker NOT Going Psycho

1
The Joker [holding a knife inside Gambol's mouth]: Wanna know how I got these scars? My father was....a drinker. And a fiend. And one night he goes off crazier than usual. Mommy gets the kitchen knife to defend herself. He doesn't like that. Not. One. Bit. So, me watching, he takes the knife to her, laughing while he does it. Turns to me and he says "Why so serious?" Comes at me with the knife,"Why so serious?" He sticks the blade in my mouth. "Let’s put a smile on that face!" And... Why so serious?

Gentleman at party: We're not intimidated by thugs!
The Joker [as he smacks his lips]: You know, you remind me of my father. [pulls out his switchblade and brings it to the Gentleman's mouth]
The Joker: I hated my father!
Rachel Dawes [off screen]: Okay, stop! [turns to face Rachel, tosses the Gentleman to his thugs and approaches Rachel, adjusting his hair with the knife]
The Joker: Well, hello, beautiful. You must be Harvey's squeeze, hmm? And you *are* beautiful. [hovers around the incredibly nervous Rachel]
The Joker: You look nervous. Is it the scars? You want to know how I got 'em? [grabs Rachel's head and positions the knife by her mouth]
The Joker: Come here. Hey! Look at me. So I had a wife, beautiful, like you, who tells me I worry too much. Who tells me I ought to smile more. Who gambles and gets in deep with the sharks... look at me! One day, they carve her face. And we have no money for surgeries. She can't take it. I just want to see her smile again, hmm? I just want her to know that I don't care about the scars. So... I stick a razor in my mouth and do this... [mimics slicing his mouth open with his tongue]
The Joker: ...to myself. And you know what? She can't stand the sight of me! She leaves. Now I see the funny side. Now I'm always smiling! [Rachel knees the Joker in the groin; he merely laughs it off]
The Joker: A little fight in you. I like that.
Batman: Then you're going to love me.

The Joker: And here we...go! [Batman slams The Joker’s head on a table]
