A driver was stopped for speeding. Asked his occupation he replied, "Rectum Stretcher!"
"What the hell is that," asks the police officer.
The driver says, "First you put one finger in, then two fingers in and then a fist in etc, until it's six foot wide."
"What do you do with a six foot arsehole??" asks the policeman.
The driver replies, "Give it a uniform and a speed gun."
