A man walks into a bar, sits down and drinks a beer. Then he drinks another beer, and another and... soon he needs to take a leak. He’s standing at the urinal in the men’s room, when he looks over and notices three black men standing at the other urinals. He notices that the one in the middle has a white cock. He zips up and, still a bit confused, goes back to the bar. He orders another brewsky and mentions to the bartender, ”I was in the men’s room and noticed three black men in there. I swear the one in the middle had a white cock!
The bartender says, pointing, ”You mean those three guys at that table over there?”
”Yes”, the man says, ”They’re the ones.”
”Well,” replies the bartender, ”those guys aren’t black. They’re coal miners. The one in the middle must have gone home for lunch.”
