Monica and Chandler decide to throw a costumed Halloween party. Meanwhile, Phoebe runs into Ursula, who's preparing to get married soon, and as a courtesy invites her and her fiancé to the party. When they finally meet, Phoebe takes an instant liking to him, but soon she discovers that he knows nothing about the "real" Ursula.

Chandler hires a maid, whom Monica suspects is stealing her clothing. Eric has broken up with Ursula and is ready to date Phoebe, except for one problem: he can't look at her without seeing Ursula. Meanwhile, Ross tries to get Rachel an apartment in his building, but the woman living there isn't in a hurry to die, and Joey wants Rachel to stay with him.
