A Man with Problems

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

Again, the man orders a beer again saying, "Give me a beer before problems start!" The bartender looks confused.

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, "Ah, now the problems start!"
