A story about hot/ground reversed came to my mind. It happened a few years ago here in Austria, and I can't remember the exact details. However it was about the following: A guy repaired or built his own pool. When working at the pump he reversed hot/ground. Then he jumped into the pool. His wife saw him, thought he fainted and jumped in too. Their som saw them, but was bright enough to switch off the power. I think they survived, but I'm not sure.
