You Chowderhead. You'll do what he says and take what he gives and hope it's not a bullet!

- Big Bad: The Joker.
- Big "NO!": Harley does this in a high-pitched scream after the Joker falls to his apparent death.

out of his ass. - Bound and Gagged: Mary Flynn (actually a disguised Harley Quinn) at the beginning of the game.
