Ursula Pamela Buffay (Lisa Kudrow): Phoebe 's identical twin. Kudrow originated the role of Ursula in the sitcom Mad About You, playing her as an inept waitress at Riff 's who frequently forgets orders. Ursula is every bit as odd as Phoebe is, but, unlike her sister, Ursula is a selfish, amoral, abrasive, brazen, hedonistic, crude and unpleasant individual who is so self - absorbed and self - centered that she often forgets things, usually treats Phoebe with disdain and is not liked by anyone who truly knows her. Phoebe refers to Ursula as her "evil twin. '' She first appears in Friends in "The One with Two Parts '': Chandler and Joey are eating at Riff 's and mistake Ursula for Phoebe. Joey becomes attracted to Ursula and they start dating. Ursula tells Phoebe that she is bored with Joey and sarcastically claims that he is smart enough to figure this out on his own without her having to actually tell him (implying his stupidity irritated her, hence her naturally nasty reaction), so Phoebe pretends to be her sister to let Joey down gently. In the same episode, Helen Hunt and Leila Kenzle cameo as their Mad About You characters Jamie Buchman and Fran Devanow, in a scene where they mistake Phoebe for Ursula in Central Perk. Ursula next appears briefly in "The One with the Jam '', where she is being stalked by a man (David Arquette) who mistakes Phoebe for her. Phoebe naively begins a relationship with the man in question, but ends it with him when he can not get over his obsession with Ursula. In "The One with the Jellyfish '' Phoebe tells Ursula that she has met their birth mother (Teri Garr), but Ursula already knows about her. In "The One Where Chandler Ca n't Cry '', Phoebe starts getting unwanted attention from men, and discovers that Ursula is starring in pornographic films using Phoebe 's name, including a film called "Buffay The Vampire Layer ''. Phoebe gets revenge by claiming Ursula 's cheques and embarrassing her many male fans. Flashbacks in "The One Where They All Turn Thirty '' reveal that Ursula sold Phoebe 's birth certificate to a Swedish runaway, and that both sisters are 31, not 30. In "The One with the Halloween Party '', Ursula introduces Phoebe to Eric (Sean Penn), her fiancé. Phoebe is horrified that Ursula has told Eric that she is a teacher, a member of the Peace Corps, a non-smoker, and attends a church group (all lies). The series finale of Mad About You, set 22 years into the future, reveals that after a successful porn career, Ursula becomes Governor of New York.
