RAY: A man was on his way to a family reunion when he noticed the odometer on his car was about to turn over at 100,000 miles. A big deal, right? When he arrived he told his family that he had watched as it happened. His skeptical brother said, 'I don't think so. I bet you really missed it. I think you just discovered that it turned over when you arrived and turned off the engine and you saw that it was over 100K miles.'

But the man was prepared. He said, 'No, I watched it turn over and I can prove it.' And no. . . he didn't take a picture or video. He didn't have a camera phone or anything like that. Still, what he showed his brother did the trick. What did he point out when they both went out to the car?
