10. THE NAME GAME
Fourth season finale, May 7, 1998
"The One With Ross's Wedding"
"Friends" was big on the May sweeps gimmicks, twisting the soap opera in all kinds of crazy contortions (Rachel and Joey? Please.) to get viewers excited. But the fourth season finale, filmed in London, had a great zing, when Ross delivers the Freudian slip heard round the world, saying "Rachel" instead of "Emily" during his wedding vows. The episode, featuring a guest appearance by Hugh Laurie long before "House," also marked the beginning of the Monica and Chandler affair.
