A passenger in a taxi leaned over to ask the driver a
question and gently tapped him on the shoulder to get his
attention.

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 window.

For a few moments everything was silent in the cab. Then the
shaking driver said "Are you OK? I'm so sorry, but
you scared the daylights out of me."

The badly shaken passenger apologized to the driver and
said, "I didn't realise that a mere tap on the
shoulder would startle someone so badly."

The driver replied, "No, no, I'm the one who is
sorry, it's entirely my fault. Today is my very first
day driving a cab.

I've been driving a hearse for 25 years."
