Too much to Drink?

A man sitting at a bar was really drunk when he decided he had to use the restroom.
He stumbled off to restroom a few seconds later.

After some time had passed the bartender heard this horrifying scream.
Since the other customers were starting to leave because of the noise
the bartender went back to see what the problem was.
When he got back there the bartender asked what the problem was.

The drunk said "I don't understand everytime I flush the toilet
something squeezes my nuts, will you look and tell me what the problem is?"

The bartender looks over and says

"Man I don't know how to tell you this but your sitting on the mop-bucket."
