Over the weekend, Steve bought a new car. He was so excited about it that he had to take a picture of it to bring to work with him to show everyone. The picture was a Polaroid snapshot of his wife sitting in one of the front seats.Steve crowed as he showed the picture to co-worker Jim, „It’s got power steering, anti-lock brakes, cruise control and a driver’s side air bag.“Jim squinted at the picture. Having never seen Steve’s wife before, he asked, „Who’s that?““Oh,“ said Steve with a grin, „another feature, my passenger-side wind bag!“
