A tourist is picked up by a cabbie in New York on a dark night
The passenger taps the driver on the shoulder to ask him something.
The driver screams, loses control of the car, nearly hits a bus, drives up on the sidewalk and stops inches from a shop window.
The driver said, "Look friend, don't ever do that again
You scared the daylights out of me!"
The passenger apologized and says he didn't realize that a "little tap" could scare him 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 hearses for the last 25 years."
