Drinking Before

A man hurriedly walked into a tavern. He dashed up to the bar and said to the bartender, "Gimme a double, before it hits the fan." The man guzzled down his drink, and a few minutes later, came the same urgent request. "Gimme a beer before it hits the fan."

This goes on for an hour or so. Finally the Bartender goes up to the guy and says, "Listen buddy, maybe you should pay before you get another drink."

The man replied, "Oops, looks like it just hit the fan."
