The taxi.. :d

A passenger in a taxi tapped the driver on the shoulder to ask him something.

The driver screamed, lost control of the cab, nearly hit a bus, drove up
over the curb and stopped just inches from a large plate glass window.

For a few moments everything was silent in the cab, then the driver said, "Please,
don't ever do that again. You scared the daylights out of me."

The passenger, who was also frightened, apologized and said he didn't
realize that a tap on the shoulder could frighten him so much, to which the
driver replied, "I'm sorry, it's really not your fault at all. Today is my
first day driving a cab, I have been driving a hearse for the last 25 years.
