A man walks into a bar and says, “Give me a beer before the problems start!”

He drinks the beer and then orders another saying, “Give me a beer before the problems start!”

The bartender looks confused but gives him another beer.

This goes on for a while, and after the fifth beer the bartender is totally confused and asks the man, “When are you going to pay for these beers?”

The man answers, “Now the problems start!”
