Stop in for a cup of coffee

But only one
There iis a joke about a guy who was a born loser.
Never won anything. one day at the doctors during an exam the doc remarks I never saw anything like this before.so the loser asks what's wrong.
Doc say nothing except you have 4 testicles.
Average man only has two.
So with this knowledge he walks into his favorite bar that night and announces I want to bet. Before he can even say on what everyone is putting up money on the bar.
The bartender figures this guy has to know something..
So he agrees to cover all the bets.
The born loser is so touched he decides to add the bartender into the bet.
So he announces . I bet between myself and the bartender we have 6 testicals
More money goes up on the bar. At this point the bartender reaches over and firmly puts his hand on the losers shoulder and whispers in his ear pal you better be holding 5, cause I only have 1.
