A taxi driver driving a Mercedes-Benz picked up a rather simple looking fellow at the airport one day.

When the gentleman got in and they started on their way he enquired what the three pinned emblem on the front is for. The driver replied "why it's for lining it up at people so you can run them down".

"Ah I see", said the man.

With this the taxi driver starts heading straight for an elderly woman but at the last second swerves away and hears a loud bang, he looks curiously over at the passenger who is hanging out of the car with the door wide open: "I thought you were going to miss there for a minute!".
