The Taxi Driver
A passenger in a taxi leaned over to ask the driver a question and tapped him on the shoulder.
The driver screamed, lost control of the cab, nearly hit a bus, drove up over the curb and stopped inches from a large plate glass window.
For a few moments everything was silent in the cab, and then the shaking cabby said, "I'm sorry but you scared the hell out of me."
The passenger apologised to the driver and said he didn't realise that just a mere tap on the shoulder could frighten him so much.
The driver replied, "No, no, I'm sorry, it's my fault. Today is my first day driving a cab."
"You must be very nervous. What was your last job?" inquired the passenger.
The cabby replied, "I used to drive a hearse for the last 25 years."
