Policeman – Level 1

One night a policeman is waiting in his car near a very busy bar. At 1 am, he can see a man who is walking out of the bar. The man goes slowly. He looks very drunk. He tries his key in five different cars. Then he finds his car. He sits in the front seat and he tries to start the car with his keys for 10 minutes. Everybody from the bar goes home. When he starts his car, he begins to drive.
The policeman is waiting for him. He stops the driver. Then he does the test for alcohol. The test shows 0.0. The policeman doesn’t understand. He wants to know how it is possible. The driver says, “Tonight, I’m playing the drunk man.”
