A woman goes into a bar and orders a bottle of champagne. She takes the first glass and pours it down the back of her skirt.

The bartender looks on in amazement as she pours another glass, and again tips it down the back of her skirt. His curiosity piqued, the bartender quickly inquires, "Lady, why are you pouring your drinks down your skirt?"

To which the woman replies, "I've just won the lottery and this is the only asshole I'm sharing it with!"
