LOL, that happened to me on my LTR, except that the peg didn't break...my foot slipped off.
I even had the OEM heel guards on, and somehow my foot managed to get wedged up in there.
The paddles on the left tire clawed their way up my leg and started pulling me down off the quad, lost my grip on the right side of the handlebar and made the tires cut to the left.
By this time I was almost to a stop, but there was just enough momentum coupled with the slope of the dune that it slowly and dramatically rolled over while I stood up and watched it roll over without me.
Felt like I broke my femur, the paddles felt like they shredded the meat off my leg, and it felt like I was being split in half starting from the crotch...I don't think I've ever done splits except for that one inadvertent moment.
Nothing needed stitches, and I still have no idea how my foot slipped off the peg.
210Zilla and atvmxr were there and we were taking videos of each other's jumps, but nobody managed to film that one...it was at least a 50ft jump and 6ft of air.
