I was a passenger on a dirt bike when I was a kid and lost the passenger peg, it had turned so it folded down. I reached down to right it and laid my forearm on the spark arrester, when I pulled away it left sizzling skin stuck to it. I have had plenty exhaust burns in my line of work but that one was bad. Also done the reallt stupid move a few times of welding a piece of steel then immediately grabbing it with my ungloved hand.

I learned all I need to know about life by killing smart people and eating their brains.
Eat right ,Exercise ,Stay fit, Die Anyway!
