Season 6: Episode 122: The One After Vegas
Picking up at the Las Vegas chapel where we left them, Chandler and Monica look on as Ross and Rachel stumble out of the chapel, blind drunk and newly married. Joey and Phoebe rush in, trying to stop the wedding but learn from Chandler and Monica that they're too late. The next morning Ross and Rachel wake up in the same bed and have no recollection of the events from the night before. When Rachel gets up to use the bathroom, Ross rolls over and the words "Just Married" are scrawled across his back. At breakfast the gang tells the newlyweds they got married last night. Rachel immediately wants a divorce, but Ross is reluctant, fearing he'll become "that guy" with the three failed marriages. Joey and Phoebe drive back from Vegas in her cab after Joey convinces her to have a "Frienaissance". Phoebe bonds with a hitchhiker the pick up along the way. Chandler and Monica agree to let fate decide whether they should get married. But after a series of overt signs, which indicate they should go through with the wedding, they both admit they feel they're rushing into it. However, they still take a huge step in their relationship when Chandler asks Monica if she wants to live together and they decide to do it. Meanwhile, at the coffeehouse Phoebe and Rachel are waiting for Ross to return from finalizing the annulment. He tells Rachel that the annulment is complete, but when Rachel goes to grab her coat, Ross whispers to Phoebe he didn't go through with it...
