Season 9 Episode 16
The One with the Boob Job
When Monica and Chandler are financially strapped, she secretly asks Joey for a large loan. When an unsuspecting Chandler also approaches his pal for some cash, Joey accidentally betrays Monica’s confidence and then freaks out Chandler when he covers by saying she wants the money for a breast enhancement. Meanwhile, Phoebe asks Mike to move in with her, but changes her mind after a disagreement about marriage. Rachel’s attempt to baby-proof the apartment tampers with a frustrated Joey’s sanity.
