The One With the Stain

S8 E7: Ross is happy to learn that pregnant Rachel wants to find her own apartment. He suggests a vacancy in his building but later discovers that the elderly occupant is not dead yet, as he had assumed. Ross gets some tough competition from Rachel's roommate, Joey, who creates a nursery in their apartment to persuade her to stay. Meanwhile, Phoebe is ecstatic when Eric (recurring special guest star SEAN PENN) ends his relationship with her twin sister, Ursula (also played by series star LISA KUDROW), and chooses Phoebe instead. Monica becomes agitated when she suspects that her new maid is stealing her jeans, among other things.
