A man gets into a cab and tells the driver where he wants to go. About half way there the guy remembers he is supposed to get milk on the way home. He reaches up and taps the taxi driver on the shoulder. The guy screams, drives up over the curb, knocks over a fire hydrant, and crashes through a plate glass window of a restaurant.
The man says to the cabbie, "I'm so sorry, I didn't mean to startle you so badly!"
The cabbie says, "No, no, it's my fault. This is my first day driving a cab. For 20 years I drove a hearse."
