The One That Could Have Been - Part 2
The One Where Ross Dates A Student

Rachel and Phoebe take self-defense classes. Ross, who had previously practiced karate, tries to attack them by surprise and convince them that they lack unagi, supposedly a state of "total awareness". (In reality, as pointed out by Rachel and Phoebe, unagi is just a Japanese dish.) Chandler and Monica celebrate Valentine's Day several days after the actual date because of their schedules, but they forget to make each other home-made gifts: Monica gives Chandler one of Phoebe's "sock bunnies", and Chandler gives Monica a mixtape, which was originally a present from Janice.
