A sudden thought

I love a good magneto story. I was in my early 20s and found a good deal on an old boat & motor while I was stationed in Homestead Fl. The motor was an old Merc that had magneto ignition. On the side of the mag was a post that connected to a kill switch to ground out the ignition. Hold that thought. I took the mag out and cleaned it up. After cleaning, I wanted to check to see how well the shaft turned, so I held the body in the palm of my left hand, and spun the magneto shaft with my right hand. Now is the time to retrieve the thought of the grounding post. That post was right in the middle of the palm of my left hand. I immediately saw stars, and involuntarily threw that magneto across the room, putting a dent in the wall and cracking the mag cap. That's my magneto story. what's yours?
