Trip To The Urinal

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?
