We had two seperate visitors at a school. One was 2nd dan in goju,the other was shaolin kung fu self proclaimed master who was always taunting people to full contact spar after classes. The school was a kempo/gung-fu school and the head instructor allowed the kunf fu master to spar his top blackbelt after class one day. It didn't last long,the kung fu master took him down repeatedly slamming him,basically ground and pound. He then challenged the goju guy for the following week.The kung fu master was supposedly training for nhb competetions,he was also very arrogant and quick to tell you everything he knows.The goju guy doesn't show up for two weeks,but when he did he was challened again.The head instructor said ok,but after class. They bowed and kung fu master went for a takedown,the goju guy stepped off to a 45 stepped on his foot and gave him a nice shuto on the back of his neck,which sent him to the floor.He did this same technique the second time,the kung fu master looked up from the floor and told him that he wouldn't "let" him do that again. As soon as he stood up he went for the takedown again,same result! He decided that the match was over and faulted the goju guy for not sparring fair. It was very funny for all those who saw it.
