I had buddy with a penchant for cheap used cars and knockoff Rolex's. One night he couldn't get his '74 Datsun to turn over, the thing was pushing 20 years of hard use. He lifts the hood and is tinkering around. I'm holding the flashlight for him and the guy next door is cranking it every time he shouts for him to. He's tinkering around with the ignition system & before I can warn him, the metal band on that ten buck Rolex comes too close to the metal distributor cap in mid-crank. A thin blue arc shoots up, his head flies into the hood, and the hood falls on top of him knocking him senseless. It was a true Kodak moment.
I saw him a couple of days later, he was still a little wobbly. He still has no memory of what had happened. A little Japanese car DIY shock treatment.

Imagine the views you'd get if that happened in the smart phone / youtube era.

I've actually thought about that over the years, MDK. That guy was a walking accident waiting to happen.
