Good thinking

One day, three friends went to this "Gentlemen's Club." One of the friends wanted to impress the other two, so he pulls out a $10 bill. The "dancer" came over to them, and the one friend licked the $10 and put it on her butt.
Not to be outdone, the other friend pulls out a $50 bill. He calls the girl back over, licks the $50, and puts it on her other cheek.
Now the attention is focused on the third guy. He got out his wallet, thought for a minute... then got out his ATM card, swiped it down her crack, grabbed the 60 bucks, and headed for the door.
