I think he was actually sliding down the backside, so looks like it chin'd him something serious, like an upper cut from HeMan...I'd like to know how messed up he his. There's very little on this planet that I have to look away from or risk puking. That's one of em. Nice job.
I've got metal bars in my 4 upper front teeth from having knocked them out three-as of recently-times. And that was on soft dirt/tree roots. **** that concrete.
