A taxi driver picked up his passenger. As they were driving along the passenger tapped the driver on the shoulder to ask him a question. The driver jumped, screamed, lost control of the car, nearly hit a pole, went up on the curb, and stopped inches from a building. Everything was quiet in the cab, until the driver said, “Please, don’t ever do that again. You scared me half to death!” The passenger apologized and said, “I didn’t realize a little tap would scare you that bad.” “Sorry, it’s not really your fault,” the driver replied. “Today is my first day as a cab driver. Before this I was driving a funeral hearse.”
