Three guys are in a strip club. One guy walks over to a stripper, licks a 50 dollar bill and sticks it to one side of her butt.
The next guy doesn't want to be shown up so he takes a 100 dollar bill, licks it, and sticks it to the other side of her butt.

The third guy doesn't want to be shown up but he doesn't have any money. He thinks for a moment and suddenly he gets an idea. He walks over to the stripper, takes out his ATM card, slides it down the crack of her ass, takes his 150 dollars and goes home!
