This is a little somethin' taken from 10th Planet Watch. You can also get this choke straight from the Kung Fu move or Mad Dog. Here's what the kid had to say about it:
“I do not pretend to be an expert on the rubber guard or anything Jiu-Jitsu. This was taken the same night that we “discovered” the counter. (no, we don’t train at Matt’s house – We didn’t have a camera with us at the college). Also, I don’t know if anybody else has ever done this / discovered this before us, I have just never seen it before and thought is was worth sharing. One last thing: I know that I have a crappy Kung Fu move! I’m sorry, I’m working on it. I said I wasn’t an expert.”
