Batman

Batman is a superhero, duh, he drives the bat mobile and likes to come out at night to destroy villains, most favorite, the Joker. He parades on his saving the world escapades dressed all in black, looking like a bat, obviously. Though during the day he leads his double life as a normal, handsome, hardworking man. So, he has a secret identity, but the real secret is many think his name is Bruce, but it's actually Paul.

Batman : Yes, so here's the thing, my name is Bruce.

Girl (who knows him) : No actually, it's Paul.

Batman : Shh, don't tell people it's fun having a secret, secret identity.

Girl : Right,... no one ever said you were sane...
