It is hard to believe some of them are true, but then read the series "The Darwin Awards". It is truly amazing how stupid some people are.
Now I have a true story -
Back when I was 18 or 19, I was delivering business machines and picking up others to take to the shop for repairs. Company policy was to never take (detachable) cords for several different reasons. So I had this calculator and I was waiting for a signature on the paperwork. This guy was sitting on the desktop, perhaps it was lunchtime and he was relaxing, I dont' know. Anyway he was swinging the cord in a circle, just for something to do and he was going to put the female (live) end in his mouth. I said "you know that is still plugged in…" He dropped it and said 'Uh, I wasn't going to put it in my mouth." He would have of course if I hadn't said something, but I always wondered what would have happened if he had. A nasty burn for sure, I wonder if it would have killed him?
