Night At The Strip...

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.........then the 
banker in me took over. I got out my ATM card, swiped it down 
her crack, grabbed the $60 bucks, and went home.
