A guy in a taxi, wanted to speak to the driver so he leaned forward and tapped him on the shoulder.
The driver screamed, jumped up in the air and yanked the wheel over. The cab mounted the kerb and stopped inches from a shop window.
The startled passenger said, " I didn't mean to frighten you. I just wanted to ask you something."
The shaken taxi driver replied," its not your fault sir. Its my first day as a cab driver.......I've been driving a hearse for the past 25 years."!!!!
