Unless it's a MMA tournament, which it doesn't appear to be so, there are other events besides fighting or sparring to compete in. There's also board breaking and forms; and since that one dude who lied about his colleague passing away in the movie was working on getting him to break boards, I wonder why he didn't just see about competing in board breaking so he'd be making good on what he said he signed up for and had cops show up so they'd be ready to arrest him for causing trouble. Personally, I disagree with that technique for board breaking that he was trying for that dude who was setting him up. The best chance of breaking a board with a hand technique would be the palm heel thrust, and I prefer the downhill one because there's a good chance of breaking through at least two or three if he does. I've never heard of trying to break boards by punching them in a school like that.

I haven't gotten to it yet because of I have about 30 minutes to go with the commercials and have seen how that one evil martial artist is pretending to be nice to the karate brat (brat being just a joke). He did get overly angry when Mister Miyagi did the predictable thing of bringing him a broom though. I knew ahead of time that he probably would do that. Of course, I know the character was wanting to learn how to do a ground sweep kick; and I could teach someone that one in a few seconds and have shown a student who was in the same martial arts class as me how to do it. It can be rough on your left knee if you're right handed and rough on your right knee if you're left handed and practice it a few times. I had pretty much begged the first instructor I had to teach me after watching someone do it at a tournament just to mess around more than anything else because ground sweeps weren't allowed in sparring.
