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, son?" 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... [looks sidelong at Gambol's thug, watching the whole thing in horror] Why so serious?
Second:
The Joker: Well, you look nervous. Is it the scars? You want to know how I got 'em? [He grabs Rachel's head and positions the knife by her mouth] 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, hm? 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... [the Joker mimics slicing his mouth open with his tongue] ...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!
The second speech is similarly geared to Rachel. Little is known about Rachel's character except that she is a hard-headed woman making it in a man's world. She is tough, persistent, courageous and an ardent follower of justice. Having chosen such a life how can she risk the vulnerability of being in love? Her very noble choice of pursuing a career in law precludes the possibility that she ever have a loving family relationship. When Joker describes a husband/wife relationship with a despairing wife who has been pummelled by a cruel masculine world he is describing the possible world Rachel would experience were she to ever slip and let herself fall in love. Moreover, his maiming of himself (allegedly) represents the despair that the wife would experience which knows no remedy but more despair; a self-sacrificing husband whose very act of self-sacrifice causes only more sorrow. What else could a woman like Rachel expect but that the beautiful man she loves be tortured and maimed by the world? What else could she expect but that "the sharks" would come for them both eventually?
The two speeches also are conversely to male and female figures - thus to all people. A masculine story of father dominance, like Saturn devouring his children, for the young boy in Gambol. And for the little girl in Rachel, a feminine story of loss and sorrow, like Niobe or Rachel mourning and weeping because they are nought. The futility of power that emasculates the male; the helplessness of weakness that crushes the female. Adam's curse of "earning his bread by the sweat of his brow"; Eve's curse of "bearing her children in pain". Joker is the universal Satan in this instance and like Satan he breeds amongst his victims intense despair in the face of his irresistable evil.
