Friends: 16 Easter Eggs You Totally Missed
12. The Arquettes
The opening credits are an iconic part of Friends - the fountain, the music, the hand-clap - and they didn't change all that much over the course of 10 seasons, save for updating the clips.
One change that did happen, though, was once Courteney Cox married David Arquette, and changed her surname. For the first episode after their nuptials, the producers paid tribute to them by having every name in the credits end with Arquette, which was a nice touch.
The episode, The One After Vegas, was dedicated to Courteney and David, "who did get married." Unlike Chandler and Monica, who came close to having a wedding of their own in Vegas.
