Old man had rules. Had to sell it. Think he respected my creative problem solving efforts, knowing full well they were pure BS. Still have a slight scar on bicep. Not like I ran the nail through my foot. More of a flesh wound. But a nail through the sole of my shoe and into my foot none the less. Had to get a tetanus shot - couldn't risk threat of 'lockjaw'. Whatever that is. Solution still works and makes sense. To this day, seem to find a reason to get a tetanus shot every five years or so without stepping on a nail. Usually in urgent care or emergency room.
