A guy was at a crowded bar having a good time when he had a sudden stomach ache and needed to go realy urgently for a shit. He asked the bartender where the toilet was and was told it was upstairs...
He ran up the stairs frantically looking for the toilet, but could not find one... Suddenly, he found a hole in the floor and said, "Man... I really need to go!". So he proceeded to take of his pants and squat on top of the hole and let it all out. Finished and satisfied, he started to go back down...
On his way down, he noticed that it was all very quiet in the once noisy bar. To his surprise, he found the whole bar empty. Then he saw the bartender crouched behind the bar counter. He called out, "Where's everyone?"
The bartender asked him back....
"Where were you when the shit hit the fan?!?!"
