Phoebe: Yeah, now we can kick anybody's ass.
Ross: After one class? I don't think so.
Rachel: You want to see me self-defend myself? Go over there and pretend you're a sexual predator. Go on, I dare you.
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.
