A taxi passenger tapped the driver on the shoulder to ask him something. The driver screamed, lost control of the car, nearly hit a bus, went up on the footpath, and stopped centimetres from a shop window. For a second everything went quiet in the cab, then the driver said

"Look mate, don't ever do that again. You scared the living daylights out of me!"

The passenger apologised and said he didn't realise 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."
