You can read them in the following list!
1. Like Monica and Chandler, Courteney Cox and David Arquette had trouble getting pregnant.
2. Producers originally wanted Courteney Cox to play Rachel, but she asked to play Monica because the character was so strong.
3. When Monica pops up from underneath Chandler’s bedsheet in London, the two of them held position for 27 seconds.
4. Monica and Chandler’s twins are born three minutes and 46 seconds apart.
5. This episode was the sixth season premiere. It was also the first episode after Courteney Cox married David Arquette. In the credits, her name was switched to “Courteney Cox Arquette” and the other cast members followed suit with new names like “Jennifer Aniston Arquette,” “Lisa Kudrow Arquette,” and so on. You can see the credits above. The episode is dedicated: “For Courteney and David, who did get married.”
6. In 1997, Perry went to rehab for an addiction to prescription drugs and alcohol. He went again in 2001. He later told People, “I was never high at work. I was painfully hung over. Then eventually things got so bad I couldn’t hide it and everybody knew.”
7. Kudrow got pregnant with her son, Julian Murray, in 1997. Kudrow was dubious about Phoebe getting pregnant too, but the writers decided to have Phoebe act as a surrogate for her brother’s triplets. On the other hand, in the final season, Cox was pregnant with her daughter, Coco Arquette. This was not written into the show for an obvious reason: the series had already established that Chandler and Monica couldn’t have kids. So, they hid Cox’s pregnancy to the best of their abilities with costumes and props.
8. While promoting the show on The Tonight Show with Jay Leno, Cox told the story of an elaborate bet between her and Perry that later involved the major ’80s star. “One day I was on the set, and I was sitting around, reciting this line, like, doing this imitation of Anthony Michael Hall,” she told Leno. “He has this line in a movie. The line is, ‘Chicks cannot hold their smoke, that’s what it is.’ And Matthew Perry walks over to me and very adamantly says, ‘Oh, Weird Science.’ And I said, ‘No, Matthew, that’s The Breakfast Club.’ And he was 100 percent sure that it was Weird Science and I was 100 percent sure it was The Breakfast Club.” More and more crew members got involved in the debate and the stakes kept rising. “We realized that Judd Nelson was over on stage 29, doing Suddenly Susan,” said Cox. “So, we ran over there and found out that yes, indeed, it was The Breakfast Club.” As for the bet, once Cox finishes telling her story to Leno, she rings a bell and Perry brings her a tissue. She tells Leno that Perry has five more months of being her “man slave.”
9. The entire world knows that Chandler is “the funny one.” Except, apparently, his friends. He’s constantly cracking jokes and they’re constantly not laughing at them. What’s the point of having Chandler in their group if they don’t think he’s funny? I might think, oh it’s a television thing. The director doesn’t want to ruin the flow of the scene by stopping for laughs, but, oh yeah, there’s a laugh track. Faceless strangers are laughing at Chandler’s jokes, but his best friends aren’t. That’s so depressing.
10. Apparently Perry was quite the gambler. He got into a debate with Willis while the two were making The Whole Nine Yards. Perry believed that the film would be number one in the box office on its opening weekend, but Willis disagreed. In February 2000, the film was number one. Willis was set to appear on Friends as the dad of Ross’s girlfriend and Rachel’s love interest. As a result of the bet, he had to donate his earnings for the guest stint to charity.
11. When the show was first written, Joey and Monica were intended to be love interests.
12. Courteney Cox is actually older than David Schwimmer, despite playing his younger sister.
13. Kudrow said that she was surprised to hear Perry’s interpretation of Chandler at the first table read because when she first read the script, she thought Chandler was supposed to be gay. And she wasn’t the only one. During the first few seasons of the show, many fans speculated about Chandler’s sexual orientation. In 1997, David Crane told Entertainment Weekly, “No, Chandler isn’t gay. Nor will he be gay.”
14. Courteney Cox had to film the scene in which Rachel has Emma just after having a miscarriage.
15. In the pilot, Monica forgets the name of a guy she sleeps with. Producers were worried that this would make the audience not like her, so they handed out a survey to the studio audience asking whether they thought the plot should be changed. They didn’t.
16. The frame around the peephole in Monica’s apartment originally had a mirror in it. It was broken by a crew member during the early stages of filming, but producers thought it looked good so they left it.
17. In the last episode, it is mentioned that all six characters have lived in Monica’s apartment. They have all also lived in Joey’s apartment.
18. Jon Favreau and Jon Cryer both tried out for the role of Chandler.
19. The reason Monica cut her hair so short in season four was because Courteney Cox Arquette had those streaks in her hair from “Scream 2” and they didn’t exactly match Monica’s character.
20. Monica’s apartment changed from number 5 to number 20 when the show’s writers realised that “5” wouldn’t denote an apartment on an upper level floor in a large block. So they matched, Chandler’s also changed from 4 to 19.
