Funny story:
When I was in college, we were at the beach staying at some crappy motel. We were sitting on the porch area, drinking beer, and there were some biker dudes there. Perfectly friendly, and all, but kind of drunkish.
There was a guy we were with, named Tom. He was kind of short, maybe 5’8"? But he was essentially a professional martial artist, dedicating virtually all of his free time to training. He practiced some style called Chung mo do which had a lot of crazy training for core strength and breathing. He used to hold crazy concentration stances for long periods of time that I could only hold for a few seconds.
Anyway, we’re there, and Tom comes out introduces himself to the biker dudes, shakes their hands, etc. Some fat guy shakes his hand across the table, and it goes on a little too long. And the guy won’t let go, and starts pulling Tom towards him over the table. Tom’s pretty cool, so he’s just waiting for this guy to let go, until it gets to the point where Tom is leaning over the table awkwardly, and the guy still won’t let go, and is still pulling him.
I remember watching this, and looking at Tom, and thinking, “Hrm. This may go badly.” Tom was always real cool, but he was pretty serious business if you were to fight him. Like, he could kill people. I didn’t really want to get involved in any trouble.
At this point, Tom just kind of closes his eyes, sighs, and does… something? I honestly don’t really know what he did. He just stood up, and the dude’s chair broke and the guy was sprawled out on the ground. Tom was like, “Hey, you ok man?” At this point, I stood up and was like, “Man, crappy plastic chairs. Anyway, we gotta go meet some chicks. You guys can finish off the beers!” and we ditched out.
