The stupidest thing I have ever done...

I slipped while I climbed over a picket fence when I was about 9 years old. The picket entered the outside of my thigh and because I was relaxed it pushed my pants into the hole the picket made clear down to the bone in my leg. It tore the nerves in that part of my leg so I felt no pain and I pulled the pants out of the hole and played till dinner time when my brother snitched on me. I still have a Y shaped scar on my thigh to this day.
