The singing man, the bird smell, and the lack of space drive Rachel and Monica to new attempts to get their old apartment back; when they fail to bribe Chandler and Joey with season Knicks tickets, they try making another bet... and lose again, so they have neither the tickets nor the apartment. However, while Joey and Chandler are at a game, Rachel and Monica switch apartments anyway. Chandler objects but Monica and Rachel offer to kiss each other for a full minute if they can keep the apartment. Ross gets an ear-ring. Phoebe tries to knit. Ross hates the fact that Emily has to be gone so much, so he considers asking her to move in with him... but ends up asking her to marry him; she says yes. The gang is shocked to hear the news... especially Rachel.
Chandler: Just remember to wake us up before you go-go.
Joey: Wait, wait, wait, wait, wait! Come on! Come on, let's trade! The timing's perfect, I just clogged the toilet!
Joey: Come on, man. You know I'd do it for you! Because you're my best friend.
Chandler: All right, but you can't use that again for a whole year.
