Don was looking for a little "action."  He picked up a sweet young thang 
at the bar and took her back to his hotel room. 
Little did he know she was damn near a nymphomaniac. 
After six times, she was screaming for more.  After the *eighth* time, Don 
told her that he needed to slip out for a pack of cigarettes.
On the way out, he stopped in the men's room. He stood in front of the 
urinal, unzipped, and felt a moment of panic when he couldn't find his 
dick.  After a couple of minutes of "fishing around," he finally said, 
"Look, it's ok.  She's not here!"
