Joker

You 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. He turns to me and 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?
