A guy leaves his place at the bar to go have a piss. He comes back about10 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 andput 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?"
