Strip Club

So the other day, my friends and I went to this "Gentleman's' Club." One of my buddies wanted to impress us, so he pulls out a $10 bill. The "dancer" came over to us, and my friend licked the $10 and put it on her butt. Not to be outdone, my 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 me. What could I do to top that? I got out my wallet, thought for a minute....
I got out my ATM card, swiped it down her crack, grabbed the 60 bucks, and headed for the door.
