I\'ve done the drilling thing, too, and stabbing my thumb with needle files.
I\'ve not caused myself an injury with darts but I have caused one. When I was a kid, I decided to take the dartboard, which was attached to an A1 sized bit of wood, outside and throw darts at it from the opposite side of the road. It was me and this other kid. At some point I had to pick up the flights and reattach them. When I looked up the other kid had gone. I carried on anyway and threw a dart. It flew over the bit of wood. Then there was a cry of pain. I went over and that kid was sat behind the board where I couldn\'t see him, now with a hole just above his knee where the dart has impaled him.
Mind you, on another occasion he managed to hit his little sister in the head with a dart.
