Stop Fooling Around !

A guy sitting in a bar is really looking nervous. Every time the door opens he jumps. Every time there is a noise he cringes.

The bartender after watching this for an hour finally goes over and asks, “What’s the matter with you?”

“Well I received a letter today that said if I didn’t stop fooling around with his wife he was gonna shoot me.”

For heaven’s sake, Why don’t you just stop fooling around with his wife?”

Came the reply, “I would but he didn’t sign his name!!”
