<P> In the teaser segment, Chandler (Matthew Perry) encourages Joey (Matt LeBlanc) to drink from a glass in Monica (Courteney Cox)'s fridge that appears to contain cider . In actuality, it contains rendered chicken fat . After the credits, Ross (David Schwimmer) arrives to gather everyone together for an important function at his museum . No one is ready, despite only 22 minutes remaining for them to don their formal attire . </P> <P> Phoebe (Lisa Kudrow) arrives at Monica's apartment fully dressed and ready to go, much to Ross's delight . Unfortunately, during Joey and Chandler's argument, Joey accidentally flings hummus onto Phoebe's dress . She tries to ask Monica what gets out hummus, but Monica is too distracted with her own problems . Rachel then tries to find something else for Phoebe to wear, but is unsuccessful . Phoebe eventually finds a Christmas ribbon meant to garnish a present in Rachel's room and wears that on her dress to cover the stain . </P> <P> After Chandler (Matthew Perry) comes back from the bathroom, he is dismayed to find that Joey (Matt LeBlanc) took his chair while he was up . They argue over the chair until Ross orders Chandler to get dressed . When he does, Joey surrenders the chair but takes its cushions with him . Unbeknownst to him, Chandler has already taken his revenge by hiding all of Joey's underwear, forcing him to go commando in a rented tux . Joey promises to do the "opposite" of Chandler hiding his underwear, and emerges wearing everything Chandler owns (and still sans underwear). Ross finally steps in and bans them, and indeed everyone, from the function . </P> <P> When Monica returns, she checks her answering - machine messages and hears a message from her ex-boyfriend Richard (voice of Tom Selleck). She is unable to determine whether the message was left before or after they broke up (as depicted in the 2nd - season finale, two episodes ago). In a fit of insecurity, she breaks into his voicemail, and hears a message left by another woman, leading her to believe that Richard has already begun seeing someone else . Chandler suggests the woman might be Richard's daughter Michelle (uncredited voice role), and Monica confirms this by prank - calling her . Unfortunately, Michelle calls her back, and Monica admits her indiscretions . She is unable to secure Michelle's silence on the matter, so she breaks into Richard's voicemail again to erase all his messages and record a new one . However, she has the misfortune to delete and re-record his outgoing message, humiliating herself to all the world . </P>
