A guy leaves his place at the bar to go have a piss. He comes back about
10 Minutes later, sits down at the bar, muttering & swearing very softly.
The barkeep approaches the customer and asks what the problem is.
"Oh some son-uv-a-bitch snuck up behind me while I was at the urinal and
put a gun to my head".
"Jesus Christ! What happened?"
"He told me to give him a blow job or he'd blow my brains out!"
"Yeah, then what?"
"Well you didn't hear a gun shot, did you?"
