The Batman2004

The Joker:
Stop me if you've heard this one, Batman: Two fellows in an abandoned party favor factory. One says to the other...

Batman:
Where are you keeping the gas, Joker?

The Joker:
You call that a punch line?

Batman:
I don't share your sense of humour.

The Joker:
Yet we're linked, you and I. Like comedy and tragedy. Two sides, same coin.

Batman:
The gas, Joker, or I vow I will turn your smile upside down.

The Joker:
Well, if it's gas you want...

[He throws a playing card at a brown bag, which falls to the stage floor. Batman dodges it in time]

The Joker:
Place all tray tables in their upright positions.

[Joker laughs maniacally]
