Monica runs into Richard but doesn't want Chandler to know, because it might spoil their anniversary. As an gift for Chandler, she gets them tickets to Las Vegas. Phoebe invites herself, Ross, and Rachel along as well. Phoebe compares everything about the trip to the London trip she missed last year. Ross and Rachel have to work, so they plan to come a day later. On the plane, Phoebe lets slip about Richard; Chandler tells Monica he's okay with it; later, in Vegas, they end up fighting over it. Meanwhile, Rachel (being alone in her apartment) decides to go around naked. Ross sees her from his apartment and thinks she's coming on to him. He goes over and makes an embarrassing scene. Rachel teases him about it the next day on their flight, so they both start doing their best to embarrass each other... a contest which is topped off by Ross drawing a mustache on a sleeping Rachel. Joey admits to his friends that his film's been shut down; he decides to play Black Jack to turn a $100 tip into enough money to finish the movie. He loses, but discovers something much more valuable (to him, at least): His identical hand twin. Monica, on her way to apologize to Chandler, finds a chip on the floor and places a bet at a craps table... and starts a winning streak. Chandler sees her celebrating and hugging the person next to her... and he walks out.
