Slick 60's

A guy in a taxi wanted to speak to the driver so he leaned forward and tapped him on the shoulder. The driver screamed and yanked the wheel, jumping the curb and hitting a lamppost.
The startled passenger said, "I didn't mean to frighten you. I just wanted to ask you something."
The taxi driver replied, "It's not your fault, sir. It's my first day as a cab driver. I've been driving a hearse for 25 years."

Hey, didn't you tell that at 2nd shift in Salina Grump ?

It's possible.
