This episode is season four's Thanksgiving episode.
Joey refuses to forgive Chandler for kissing Kathy, despite all of Chandler's pleas for forgiveness. Joey tells Ross he has sentenced Chandler to five years silent treatment, but Ross talks him into hearing Chandler out. However, just as Joey is about to talk to Chandler, he sees Kathy and Chandler kissing, and he decides to go looking for another apartment. Chandler is willing to do anything to get Joey to stay, so Joey decides that Chandler has to spend six hours in a box, the equivalent amount of time Joey spent locked in the entertainment center when the robber locked him in. Chandler doesn't take the punishment seriously, though, and makes a number of jokes while locked in the box. Joey is upset by Chandler's attitude and tells him so, resulting in Chandler changing his attitude. Kathy shows up at the apartment and breaks up with Chandler while he is still locked in the box. This time, though, Chandler holds his silence thus proving to Joey how much he means to him. Joey is touched by Chandler's effort and forgives him and tells him to go get Kathy.
Monica is getting virtually no help with the Thanksgiving dinner preparation. When she goes into the freezer, she chips at some ice that unfortunately hits her in the eye. However, she is reluctant to go to her ophthalmologist, who happens to be her ex., Richard Burke. When she finds out Richard is out of town and there is an on-call doctor taking his place, she becomes willing to go. It turns out the on-call doctor is Richard's son Timothy, who happens to be very handsome and has just broken up with his girlfriend. Monica, now wearing an eye-patch, invites Timothy for Thanksgiving, and despite her friends teasing her, the two of them get along great, until they kiss and it reminds her too much of Richard.
