Another naked steal from Quora:

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 kerb, and for a few moments everything was silent in the cab, and then the still shaking driver said, "I'm sorry but you scared the daylights out of me".

The frightened passenger apologized to the driver, and said he didn't realize a mere tap on the shoulder could frighten him so much.

The driver replied, "No, no, I'm sorry, it's entirely my fault. I'm new to this. Today is my first day driving a cab. I've been driving a hearse for the past 23 years.”
