My father met Seagal in the late nineties and had a good experience with him. He does seem a bit arrogant at times, but not in his interactions with my father. He was very eccentric, had a geisha servant etc. I believe the story you are referencing is with Judo Gene LaBell who supposedly choked out Seagal on a movie set, and one version of the story involves him defecating in his pants while unconscious. I think he may have trained some with John Machado on set as well, but this is just a rumor I read somewhere, and was not from him or his students. <disclaimer: I got my blue belt under John>. Good luck finding a celebrity who is humble, it is rare. Also, I have trained a little bit in Aikido and appreciate the customs/culture/ideology they are trying to teach, but find it's lack of true randori/sparring, and performing techniques under resistance troubling. That being said, some of it can be useful and effective, but you won't see it utilized much in a sport combative environment because it is contradictory to their teachings which are to protect the attacker. There are two videos that should be of interest for those curious about aikido and it's use with brazilian jiu jitsu, one is by Roy Dean, the other by Marcio Feitosa/Gracie Barra. I haven't seen Marcio's video but Roy's is well done.
