"How the heck did that happen?" Injuries

I don't usually wear gloves, but I was drilling out some rivets on a steering joint for my daughters vehicle holding the part what I "thought" was far enough below the point I was drilling. Well the bit broke thru and grabbed the glove and pulled my finger into the bit. Funny thing was some how removed my hand from the glove still wrapped around the bit. Needed a tetanus shot anyway. After the doc put a few stitches in. Just one of many over the years working aviation.
