As a kid I was mowing my grandparent's yard, when it came time to turn the mower off there was no apparent way of doing it. It was an old mower. Ahhh, I'll pull the spark plug connection. I crouch down, grapped the bare metal clip and ... next thing I knew I'm flat on the ground six or seven feet from the mower, legs out streached with electrical burns on my thumb and fore finger.
