A woman goes into a bar and orders a beer. She grabs the beer and tips it 
down the back of her skirt. The barman looks amazed as she orders another 
and again tips it down her skirt.
Finally, the barman says: "Why are you tipping your drinks down your 
skirt?"
"Well," the chick replies, "I've just won the lottery and this is the only 
arsehole I'm shouting!"
