A man is riding in the back of a taxi... and the taxi driver is silent and concentrated on the road. Wanting to ask a question, the man taps the driver on the shoulder and says ""Hey, buddy!"" The driver screams and loses control of the taxi and crashes into a pole. The man says ""Wow I didn't know me tapping you would scare you so much!"" The driver replies, ""It's not you're fault. This is my first day driving a taxi... last 20 years I drove a hearse!""
