MMA Fighter Knocks Himself Out [FBHW]

MMA's gotta be a tough sport.

You're basically signing up to get your ass kicked. You spend so much time worrying about the other guy in the ring beating you up, that you don't realize the greatest risk of all: yourself.

Watch as this guy turns his back on himself for just a second. And that second was all it took for himself to knock himself out!
