Ha, Mass roundhouse tournament's about right.
I remember going to one WTF organized tourney, and these folks from a dojang called TigerDen showed up, dressed in red-and-black gis. This wouldn't be so bad if the red and black didn't alternate from side to side in a jester's pattern (red on right shoulder, black on left shoulder, then alternating sides down the uniform).
Suffice it to say, they got vaped by our dojang right-quick. The only problem was, their instructor told one of their "black belts" to do a number on one of ours, and threw one punch that cracked the orbital bone (the one that protects the eye, in case any don't know) of one of our black belts. Our guy gets back up, and puts the TigerDen knuckle-duster down with a side kick that knocked him back several feet. The guy took a while to get up. Glass jaws, corruption, and geeky uniforms abound at McDojangs, the place where we love to see you smile as we rip the money right out of your (insert censorship of phrases that would make a sailor blush here).
