"Who am I?
Many things, so many.
I am the nightmare that makes you scream like a child for your mother.
I am the unseen laugh that makes you run for your front door.
I am the smile that makes you ache with pain.
I am the Joker.
I am he who laughs at death, and my smile is damnation"
The Joker, The Batman.

Not made by me, I like the quote though.
