"I was, like, a brown belt, which is pretty good. I entered a tournament once, and I punched the guy in the throat and got disqualified. I realized - I don't know if you're familiar with "Karate Kid," but the bad guys in that are called Cobra Kai, and they're, like, the evil karate guys. And then when I went to the tournament, I realized that's what we were; we were like the Cobra Kai of the Jewish karate community."
