The One in Vegas

The episode starts where "The One with Joey's Big Break" left off. Joey is in Las Vegas, Nevada, working at Caesar's Palace casino as a costumed "atmosphere" character; the film that was going to be his "big break" has been placed on indefinite hiatus. Chandler, who fought with Joey right before his departure over whether it would be Joey's big break, has been trying to apologize by phone, but Joey refuses to let him, particularly since he does not want to admit Chandler turned out to be right. When Joey calls Phoebe on the apartment phone, Chandler decides to fly out and visit Joey in person, which Joey overhears, so he allows Chandler to talk to him, forgiving him for the incident but warning him not to come to Vegas.

Monica reveals to Phoebe that she had lunch with old flame Richard Burke. She has not been able to tell Chandler because their one-year anniversary is coming up and she does not want him to get jealous. When Chandler arrives, Monica reveals her gift to Chandler: two tickets to Vegas for their anniversary. Phoebe buys in because she was unable to make it to Ross's wedding in London because she was pregnant with the triplets. Finally, she tells Ross and Rachel to get involved, but they decide to fly out a day later due to work commitments.

On the plane, as Phoebe goes to the restroom, Chandler realizes he forgot his anniversary present to her, but Monica immediately forgives him. Chandler replies, "This is the worst thing that can happen on our anniversary ever" the minute Phoebe returns, making Phoebe assumes that Monica told him about Richard, which causes things to become tense between the couple. When Monica, Chandler and Phoebe arrive at Caesar's Palace, they find Joey, who admits that he is working there while his movie is on hiatus, and apologizes to Chandler for not telling him. Chandler and Monica then quickly get into a huge fight over whether she may see Richard again, and split off. Phoebe counsels Monica to tell Chandler the truth: that she loves him and not Richard. Monica sets out to do so, but gets sucked into a craps game by accident and then starts winning. Meanwhile, Phoebe sets Chandler looking for Monica to receive her apology, but when he finds the craps table, she is hugging a bystander in joyous celebration. Chandler turns around wordlessly and walks away.

Rachel takes advantage of the empty apartment to act on Phoebe's suggestion and wander around the apartment completely in the nude. Unfortunately, Ross sees her from across the street and assumes she is coming on to him (or, possibly, his entire building). This leads to an awkward conversation in the hall, and then frosty contretemps on the plane the next day. After inconclusive attempts to out-embarrass each other, Rachel falls asleep on Ross's shoulder, and Ross draws a beard and mustache on her face with a pen.  

While Monica plays another game at the craps table, Chandler is towing his luggage behind, preparing to go home alone. Monica quickly apologizes to him, saying she will never see Richard again. After she proclaims that Chandler is the love of her life, he forgives her and joins her at the craps table, calling the numbers she should bet on. He makes increasingly extravagant promises to the crowd, culminating in a bet to Monica: "You roll another hard eight... And we get married here tonight." Monica agrees. She rolls a four with one die, but the other goes wild and lands beneath the table... On-edge, showing a four on one side and a five on the other. "It's a four," Chandler decides. "I think so too," Monica agrees.

Rachel is oblivious to the beard and mustache Ross drew on her face until they meet Phoebe and Joey in the Caesar's Palace lobby; she storms off to the restrooms, where she discovers that the marker Ross borrowed is permanent. She refuses to leave the hotel room but still demands the Vegas experience, leading her to eviscerate Ross's mini-bar and leading Ross to "lose" to her repeatedly at blackjack. Eventually they both get roaring drunk, and parade happily around the casino in alcoholic equality: Ross with cat whiskers doodled on his face by Rachel.

Phoebe has to deal with a "lurker"—someone (in this case an elderly woman) who takes slot machines Phoebe has just abandoned and manages to land jackpots with them. She attempts to antagonize the woman into leaving her alone. Meanwhile, Joey discovers his "hand twin"—a man whose hands are identical to Joey's; this man immediately gets drafted into Joey's get-rich-quick scheming. Both Phoebe and Joey are eventually thrown out of the casino.

The final scene of the episode finds Chandler and Monica at a Las Vegas wedding chapel: "One marriage, please!" They have to wait, however, as the chapel is currently in use. Finally, its occupants burst out in joyous celebration: Ross and Rachel, still with doodled-on faces, still roaring drunk, and now very legally married. They charge out into the night while Chandler and Monica stare in shock.
