If you have a weak stomach, don't watch this, and I'm not kidding. found video of Riley Green destroying some guy in an arm-wrestling match. He actually broke the man's forearm and you can HEAR IT in the clip.
It happened four years ago and Riley talked about it in a recent interview. Quote, "I beat like two or three different guys and they're like, 'We're gonna go find somebody.'" Yes, somebody did call an ambulance for the poor guy.
