I have a Cousin, former Army Ranger, who within his first year or two out of the service, managed to shoot himself through the meatier bit of his palm while cleaning a handgun. clean shot, nice scar, no permanent damage, but [censored]...
same guy, back in high school, working @ some fast food joint, accidentally put his hand straight down on the griddle. took a second to register...AHHHHAHAHAHAHAHAAAAAHHH!!!
again, no perm. damage. probably another nifty scar.
