I took a sharp turn on a four wheeler at near top speed, and flipped it completely over, ALMOST smashed my skull on a rock, and winded myself. I wasn't beat up terribly, (I was lucky) but I was very sore after.
I also let off a smoke (and sparks(it) grenade in the house, and burned my mouth, and a hole in the carpet.
No, I'm not very bright, why do you ask?
