How about alive? Hm?
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 he says:
"Why so serious?"
He comes at me with the knife.
"Why so serious?"
