John's car broke down in the middle of a quiet road at night. He decided to hitchhike. After waiting for a while, a car stopped next to him. He jumped aboard. The speed of the car was slow and steady. Suddenly John noticed to his shock that the driver's seat was empty. No one was driving the car. John was not frightened by the speed of the car, but by the fact that it had no driver. When the moment came, he jumped out of the car and ran for his life. After a few kilometers, John arrived at the gas station. He went inside and bought himself a drink. Two men arrived at the gas station. One of them pointed at John and said: "Look, Jack, that's the idiot who jumped into our car while we were pushing it!"
