A taxi passenger tapped the driver on the shoulder to ask him a question. The driver screamed, lost control of the car, nearly hit a bus, went up on the footpath, and stopped just inches from a shop window.
For a second everything went quiet in the cab, then the driver said: "Look, buddy, don't ever do that again. You scared the daylights out of me!"
The passenger apologized and said: "I didn't realize that a little tap would scare you 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 a funeral hearse for the last 25 years."
