A stupid man

A man drove to a town in his new car.He just brought the car a week before. When he reached the town, he parked his new car in front of a mini market. After he had locked his car, he took a rain coat & covered his car with it. Meanwhile, he saw a policeman standing near by. He asked the policeman to look after his car while he was a way. And hour later he came back found out that his car was not there. He asked the policeman where his car was. The policeman smiled & asked him to look under the rain coat that was lying on the ground there...Haha
