Ouch, that hurts just looking at it. Asshole flambe. I once had a get-off in a pair of jeans where my left ass cheek probably would have looked a lot like that but for the intervention of my wallet which took the brunt of the slide. Ground $80 in bills, my driver's license, and a couple of credit cards down to powder, but worth it. That said, don't consider a wallet part of one's ATGATT package.
Hard cases make bad law.
