I haven't seen that episode, but I love that program. The MMA one with Bas Rutten and Randy Couture is on my DVR right now and I have watched, probably, 6 times. It's pretty cool what the human body can be trained to do. I am going to see if this episode recorded and check it out.
It's really an interesting program for those that haven't seen it yet. Definitely worth an hour, or 44 minutes if you fast forward through commercials, of your time.
