I haven't seen every episode but this is a great series. It shows two men who travel the world learning different fighting styles. They were in Japan for one episode learning a form of martial arts. It was amazing. The one man had to fight three men, one right after the other. THe first guy beat his butt, yet he had to keep going. The teacher swatted him on the back with a cane and told him to attack, attack, attack. My 17 year old son looked at me and said, "That is the most awesome teacher that I have ever seen." I told him that in America, I am pretty certain that most people would get offended if their teacher popped them while they were getting beaten up. The show is excellent and it is interesting to watch how different cultures train their students for fighting. By the way, everyone was really friendly after the one guy got his tail handed back to him.
