Reality: Toughest On-air Decision

Also Ice Road Truckers host Thom Beers recalls an altercation on one of his shows, "In the middle of it they just start beating the crap out of each other. So I'm sitting in the middle of this going, so wait if I sit here I'm going to look like a big wuss and if I jump in I'm going to get my ass kicked. I got a good right to the jaw, it was like insane boom boom boom the guys were trying to kill each other, it was awesome!"
