Joey's financial needs aren't being met by his job at the coffee house, so he looks into participating in another medical study. The only one available is for identical twins, but it pays so much that Joey can't resist. He hires another actor to play his twin brother. Rachel and Phoebe are taking a self-defense class, but Ross feels they don't have Unagi, a state of total awareness, in which you can be prepared for any danger. He startles them in the hallway to prove his point, which sets off an on-going competition of psuedo-attacks. Chandler and Monica plan to celebrate Valentines day (late) by making gifts for each other. Chandler can't make anything and Monica forgets until the last minute. Chandler gives Monica a customized tape of music which actually was a previous gift from Janice; Monica give him a sock puppet that Phoebe made.
