Elliott Gould JACK GELLER One of my favorite segments would have to have been Ross’ wedding in London, because they brought me over. I made an error because I let the cat out of the bag in terms of Rachel having shown up at the wedding. [Executive producer] Marta [Kauffman] was very, very upset with me. Nobody had told me to keep my mouth shut, but it wasn’t my business. It took a while for me to get back in their good graces.

Christina Pickles JUDY GELLER There were two. One was the one where we had sex in the bathroom. It was just so brilliant. And I liked Elliott feeling my ass. The other one was the Thanksgiving episode where Rachel made the dessert with beef and peas and whipped cream. That was great [because] I had a lot to do. I always like the ones where I spoke a lot.

Maggie Wheeler CHANDLER’S EX JANICE It would have been the Valentine’s episode — Chan and Jan forever, The One With the Candy Hearts. It’s sort of a classic moment where I left him wanting me. [Fans] want to hear me say ”You love me, Chandler Bing…. You know it. You just don’t know you know it,” which I think was a great moment for a lot of women trying to shake some sense into some absent, retreating male.

Gabrielle Union THE FIRST BLACK LOVE INTEREST, KRISTEN The one with Ben Stiller as the crazy boyfriend of Rachel, who everyone loves but Ross. It reminded me of the ”perfect” boyfriend I had who turned out to have a sixth toe. Only my best guy friend noticed.

James Michael Tyler CENTRAL PERK BARISTA GUNTHER The One With the Prom Video, where Monica was in a fat suit and Rachel still had her old nose. It established a backstory of how Ross was pining for Rachel. In one of the original drafts they were going to have me as Bryce on All My Children, on a TV in the background. But that didn’t make the final cut.

Debra Jo Rupp PHOEBE’S SISTER-IN-LAW, ALICE The first one I did, where Giovanni [Ribisi] introduces me to everybody. Basically I just made out and giggled for a week, and it really doesn’t get better than that.

Christina Applegate RACHEL’S SISTER AMY The jogging episode, where Phoebe was trying to tell Rachel that if she ran stupid, she would feel better. Phoebe was a terrible runner, and Rachel didn’t want to run with her. There was a big fight, and Phoebe says, ”You’re uptight,” and Rachel says, ”Listen, I’m not uptight, man.” It made me laugh so hard.
