A drunk is sitting in a bar totally pissed. He asks the barman where the bathroom is. The bartender told him to go down the hall and make a right.
All of sudden, everybody in the bar hears a loud scream and wonders what is going on in the bathroom. A few minutes go by and again everybody at the bar hears another loud scream that came out of the bathroom again.
This time the bartender goes into the bathroom to investigate what the drunk is screaming about.
He opened the door and asked the drunk, "What's all the screaming about in here pal? You are scaring all my customers away."
"I'm sorry," said the drunk, "but when I'm sitting on the toilet, every time I flush the toilet, something comes up and squeezes the hell out of my balls."
With that the bartender opens the door and looks in and says, "No wonder, your sitting on the mop bucket you arsehole!"
