Hey Gerbil, for some reason your thread reminded me of one of your blog entries. I guess it could be titled, "Purple belt submits black belt, and black belt gets angry". I remember you wrote that when you were a purple belt in Brazil, you submitted a black belt, and he started yelling at you.
You should keep the tradition alive. Yelling is in order.
