Re: Aiki Doh's
One for which I paid dearly... not Aiki, though - a Ju-d'oh. As a gokyu practicing for the first time with Doug (godan, olympic silver medalist) Rogers. Somehow, between his throwing me around at will, I took a grip, entered; tsuri-komi-goshi happened, and there's Doug, taking ukemi, laughing all the way down. I never did figure out how I did it, but I sure got some air time after he got back up. Not nasty, just lots of time flying around the dojo.
