One of my very first days working in the machine shop, an older apprentice smashed his thumbnail pretty badly. There was a huge blood blister under the nail pushing up against the nail, and down against the nerves. He wanted to go to the hospital, but the older guys convinced him to drill a small hole through the nail with a #50, or so drill bit. They told him it would take a while, and would hurt like #%^ until he broke through the nail, but to be patient and stick with it, because the doctors were going to do the same thing, only he would have no control over the pain. So he went at and everyone drifted away back to what they were doing before. Only problem was, he got impatient, chucked that little drill bit in a micro drill press, and you all know what happened next!!! This scream echoes throughout the shop, we all rush over to where he was, and there he is holding his left hand with his right, and a broken #50 drill bit is sticking out of both sides of his thumb. Of course, the drill bit caught the underside of his thumb nail when it broke through, the blood spurted up all over the place, the bit drilled right through his thumb, and he snapped the bit in shock at what he had done to himself. And since he was on an apprenticeship program with the state, now he REALLY had to go to the hospital.
