A man in a taxi cab taps the driver on the shoulder to ask him a question. The driver screams bloody murder, loses control of the cab, and swerves onto the sidewalk before stopping just inches from a lamppost. After checking to make sure the passenger is OK, the driver says "I'm sorry, but you scared the daylights out of me!" "Sorry. I didn't realize a simple tap on the shoulder would freak you out so much," the passenger says. "It's not your fault," replies the cabbie. "Today is my first day on the job after 25 years of driving a hearse."
