Ross:Of course you can defend yourself from an attack you know is coming. That's not enough. Look, I studied karate for a long time. And there's a concept you should really be familiar with. It's what the Japanese call unagi. Rachel: Isn't that a kind of sushi? Ross:No, it's a concept. Phoebe:Yeah, it is. It's freshwater eel. Ross: All right, maybe it means that too. Rachel:Oh, I would kill for a salmon skin roll right now. Ross:Fine, get attacked. I don't even care.
