This episode is mostly about Rachel and Phoebe taking self-defense classes and Ross trying to teach them how to achieve Unagi- state of total awareness or sushi;). On the other hand we have Joey trying to find identical twin so he can earn some money that he needs.Chandler is trying to make a present for Monica but he is not good at it, so he finds a tape without knowing that it is a tape that Janice made him and she also sings on it, well is it not a treat for ears:))
Anyway Ross was great in this episode, I laughed so much when he was pretending to be a sexual predator and when he attacked wrong women.
Ross: Chandler. I sensed it was you.
Ross: Unagi. I'm always aware.
Chandler: Okay, are you aware unagi is an eel?"
