The Batman2004

Batman:
Impressive. You have all the answers, D.A.V.E., except one. Every great supervillain, as well as a superhero, has an origin too. What's yours?

D.A.V.E.:
My origin? I... I... fell into a chemical bath.

Batman:
That's Joker.

D.A.V.E.:
A cryogenic mishap. No, no. I... I lost my family fortune.

Batman:
Freeze. Penguin.

D.A.V.E.:
I was a mad psychiatrist using Arkham as my cover.

Batman:
That's Professor Strange, your creator. You can't remember your origin because it doesn't exist. You're a computer program.
