During a ride in a taxicab, the rider touched the driver on the shoulder to ask him a question.

Upon the touch, the cab driver flinched, screamed, then went into a panic and almost wrecked the cab. Finally the driver got control and pulled over to the side of road.

Still shaking, he turned to his rider and apologized. He said, "Sorry about that. This is my first day as a cab driver. For the past 20 years I have driven a hearse."
