"Bathroom problems at the bar" joke

This guy is sitting in a bar drunk, he asks the bartender where the bathroom is.

The bartender said, go down the hall & make a right. Well, all of a sudden, everybody at the bar hears this loud scream and wonders what is going on in the bathroom.

A few minutes go by again and 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? You are scaring all my customers away."

The drunk said, "I'm sitting on the toilet and every time I go to flush it, something comes up and squeezes the hell out of my balls."

With that, the bartender opens up the door and looks in and says, "No wonder, you're sitting on a mop bucket!!
