How about 3 dumb ones....First, lived on a farm, had a hay mound in the barn, brother and I were playing Tarzan with the rope only I didn't know the pitchfork was in the hay, yep, right in the thigh muscle, luckily no damage, still have the hole. 2. at a church party, kid thought it would be funny to pull the chair out from behind me when I went to sit down, hit the back of my head on the edge of the wooden chair, cost me 4 stitches. 3. When DW and I lived on farm, I was chasing one of her cats just messing around, cat ran under the car and I went to stop and you don't stop on gravel. Slid right into the bumper on our car, hit my leg right in between the ankle and knee, still have a dent in the shin from that one.
