Season 8, Episode 6: “The One with the Halloween Party”
The only official “Halloween” episode in Friends is Season 8, Episode 6, “The One with the Halloween Party.” Monica and Chandler throw a last-minute costume party, with Monica dressed as Catwoman, Phoebe as Supergirl, Chandler as a pink bunny, Ross as a Spud-Nik, Joey as Chandler, and Rachel wearing regular clothes since she’s pregnant.
During the episode, Phoebe also runs into her twin sister, Ursula, and Ursula’s fiancé, Eric (played by guest star Sean Penn). She discovers that her sister has been deceiving him about who she really is. There’s also a big debate over who would win a fight, Ross or Chandler.
