The One with Unagi

When Joey is struggling to make ends meet by working at Central Perk, Ross suggests some alternative form of employment, and Joey looks into medical studies at the local hospital. He finds one that pays $2,000 for identical twins, and hires a fake twin, Carl, at an audition. Carl is even dumber than Joey, and the ruse fails miserably.

Chandler panics when he remembers that he and Monica have agreed to hand-craft Valentine's Day gifts for each other this year, two weeks later than planned because Monica was working on Valentine's Day. After Phoebe offers him a bunny rabbit composed of Rachel's socks, Chandler fails miserably at making his own gifts. He ends up grabbing a cassette tape to stand in for a homemade mix tape. Monica, who also forgot, gives him Phoebe's sock-bunny and then launches into a furious campaign of please-forgive-me sex and homemade meals. Chandler, happy with the attention, does not correct her misconception, but his deception becomes clear when Monica actually plays the cassette tape—a homemade mix tape from Chandler's ex-girlfriend Janice for his birthday. Although she is angry, he pleads for another chance. She tries to get past it with another slow dance, but a few more seconds of Janice's voice is enough for her to storm into their bedroom alone.

Rachel and Phoebe take a women's self-defense class together; Rachel feels confident about her mastery of the topic, which Ross scoffs at. Ross claims to have years of karate lessons to master the true essence of self-defense: "unagi", which Ross claims is "a state of total awareness." (Everyone asks him, rightly, if "unagi" is actually a form of sushi. In karate, the concept of this state is zanshin.) To prove that Rachel and Phoebe have not reached an "unagi"-infused state of mind, he sets up a number of "scary" ambushes on them, only to find out they are stronger than him, as in one failed ambush Rachel and Phoebe sit on him, not letting him go. Ross goes to their instructor to ask how to fight them off, but he fails to mention how Rachel and Phoebe attacked him first, making him look like someone who enjoys attacking women, especially his ex-wife. Later, Ross sees the backs of two blonde-haired women near Central Perk, thinking they are Rachel and Phoebe and attacks them from behind, only to be attacked back. As he is running away from them he pauses for a second to see Rachel and Phoebe staring at him from a window in Central Perk and he runs away in fear as he realizes the unknown women are chasing him.
