Similar to yours Zammo- but absolutely true. A friend of mine was walking along with another pal, and burst out laughing at something that was said. Her false teeth flew out and landed in the road. As she was about to retrive them, a car pulled alongside them to turn into a driveway. Not only did it run over the teeth, but they stuck to the ridges in the tyre. My friend chased after them, and managed to pull them free. Although they were damaged, at least she was reunited!
