I did have a hole drilled in my finger once, by ME, I was trying to drill a hole in a small part, and I slipped. I always wanted to know what my bones looked like, but at the time I did not look, I just covered it up real quick, and stopped the bleeding. It cost me thousands of dollars! (I stained the rug, my wife said: "don't worry about the rug, I want to move to a bigger house! )
