Not a circuit bending accident but in school a couple of years ago I was sawing some wood vigourously and slipped, the saw went through the top of my thumb and out through the other side, cutting the top of my nail but just missing the bone.
It bled a lot and I was in great pain sat in casualty for 3 hours. They didnt even do much, just put some of those modern no-needle stitches things on there and wrapped it up so I looked ridiculous.
