About The One with Ross's Wedding

"The One with Ross's Wedding" is the two-part fourth-season finale of the American television sitcom Friends, comprising the 96th and 97th episodes of the series overall. Originally broadcast by NBC on May 7, 1998, the episode features Ross, Monica, Joey, Chandler and later Rachel travelling to England to attend the wedding of Ross Geller to his fiancée Emily in London. Ross and Emily's wedding vows are ruined when Ross accidentally says "I, Ross, take thee Rachel"; as the registrar asks Emily if he should continue, the episode ends on a cliffhanger until the season 5 premiere "The One After Ross Says Rachel". The episode also introduces Chandler and Monica's romantic relationship after they impulsively have a one-night stand. Lisa Kudrow won an Emmy Award for her work in the episode.
