I had a teacher in TKD that often had students run or do pushups for all manner of things.I got busted more than a few times for "celebrating" after a match or landing a good shot.

At the time it seemed a little extreme but looking back on it, I may have caused peoples feelings to be hurt in one way or another. In any event, it certainly didnt help anyone.

Its amazing that a teacher who teaches history or ABC's has to have a liscense and background check and yet another person can call themselves teacher and teach someone how to choke another person or how to use a knife or sword with no more than a empty roomand a "Martial Arts" sign.
