Well I have one. I was working for a car detail shop while I was laid off my regular job. Anyhow one evening we went to move a couple cars and the battery was dead so I got the owners jumper cables out to jump the car. When I had one end on the good battery I went to hook up the other end and it was an awkward and place to get to and when I touched the positive to the battery my wedding ring was against the negative side and the ring lite up like a light bulb. I tried to jerk the ring off and when it came off the skin came off with it. It was still glowing red while rolling across the floor. I have not worn a ring since.
