The Dark Knight - Wanna Know How I got ’Em (Scars)

[Joker]
Well, you look nervous. Is it the scars? You wanna know how I got 'em? 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 oughta 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 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!
