by Heath Ledger - Joker (Movie Clip)

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 he says:
"Why so serious son?"
He comes at me with the knife:
"Why so serious son?"
He sticks the blade in my mouth
“Let’s put a smile on that face!”
"Why so serious?"
