He had uncombed hair, dirty clothes, and only 35 cents in his pocket. In Baltumore, Maryland, he got on a bus and headed straight for the restroom. He thought that if he did in the restroom, he could ride to New York without paying. But a passenger at the back of the bus saw him. She tapped the person in front of her on the shoulder and said,"There's a bum in the restroom. Tell the bus driver." That passenger tapped the person siting in front of him. "Tell the bus drive there's a bum in the room." he said. The massage was passed from person to person until it reached the front of the bus. But somewhere along the way, the message changed. By the time it reached the bus driver, it was not"there's a bum in the restroom" but "there's a bomb in the restroom". The driver immediately pulled over to the side of the highway and radioed the police. When the police arrived, they told the passengers to get off the bus and move far away from it. Then they closed the highway. That soon caused a 15-mile-long traffic jam. With the help of a dog, the police searched the bus for two hours. Of course, they found no bomb.
