A taxi passenger tapped the driver on the shoulder to ask him a question. The driver screamed, lost control of the car, nearly hit a bus, went up on the footpath, and stopped centimeters from a shop window. For a second, everything went quiet in the cab; then the driver said, "Look mate, don't ever do that again. You scared the daylights out of me!" The passenger apologized and said, "I didn't realize that a little tap would scare you so much." The driver replied, "Sorry, it's not really your fault. Today is my first day as a cab driver. I've been driving a funeral van for the last 25 years."
