it's my life

A guy is really desperate to take a dump, so he goes into a nearby bar and asks the
bartender where the toilets are. The bartender says, “Go upstairs and it’s the second
door on the right.”
So the guy goes upstairs but can’t find the restrooms anywhere. So when he sees a hole
in the floor and he decides to crap in it.
After relieving himself, of a monster dump, he goes back downstairs and notices that
there’s no one in the bar.
“Hey, Where did everybody go?” He asks the bartender.
The bartender replies, “So, where were you when the shit hit the fan?”
