Trivia: The spare room (Rachel's) in Monica's apartment has a wall right opposite the door, which serves absolutely no purpose except to block the view into the room from the living room. The bedroom set isn't always built, just when needed, so having that wall makes life much easier. It's completely illogical though, as it's too thin to be a supporting wall, and where it is makes getting into the room a pain.Jon Sandys
Trivia: Virtually the only time that any apartment doors are locked is when it is important to the episode. For example, Monica's apartment door is always unlocked, even when they go out or she and Chandler are having sex, but in "The One Where Underdog Gets Away" (series 1), it's locked when there is all the "got the keys?" business. Also, Ross' apartment is never locked, except for in "The One With Phoebe's Birthday Dinner" (series 9), when they lock Emma in, and in "The One With The Engagement Picture" (S7 E4) when Phoebe has the key and unlocks the door, then Ross demands it back.
Trivia: Many famous people are mentioned in the show and some end up guest starring! Two examples of this include Ross's List from Series 3, which includes Winona Ryder, who guest stars as Rachel's friend in Series 7. Also, Joey and Ross mention their favourite movie is Die Hard, and Bruce Willis guest stars in Series 6 as Ross's girlfriend's dad ("Hey, Mr. Stevens, you look like that guy out of Die Hard!"). That is also true for Susan Sarandon and Elle MacPherson.
Trivia: In "The One Where Rachel Tells Ross", originally shot before September 11, 2001, Chandler and Monica couldn't get on their flight for their honeymoon because Chandler said the word "bomb" in the airport. After the terrorist attacks on the U.S., the story was rewritten and re-shot. The original scenes for this story can be seen on the DVD.
Trivia: The only 2 characters who have not kissed in the show are Monica and Joey. Rachel kissed Monica: to get their apartment back; Phoebe: so Phoebe could see how good a kisser Rachel was; Ross: well we all know that story!; Chandler: to hide that he and Monica were dating had to kiss all three girls after he made the mistake of just kissing Monica goodbye; Joey: the two briefly dated and first kissed in Barbados. Chandler has kissed Monica (of course), Rachel (while covering for his relationship with Monica), Phoebe (while covering for his relationship and also when on a fake date before revealing said relationship), Joey (New Year's Eve in season 1 when Chandler is complaining about not having anyone to kiss), and Ross (implied during Rachel's birthday party where he was very drunk). Ross has kissed Rachel (of course), Phoebe (when he found out his wife was a lesbian), Monica (when he was in college and thought he was kissing Rachel while she slept), Joey (when Joey had to kiss a man for a role and Ross wanted to help him), and Chandler (mentioned to have happened during Rachel's birthday when he was very drunk). Phoebe has kissed Ross (above), Chandler (above), Joey (testing his ability, pretending to be Ursula, after David leaves, etc.), Rachel (above), Monica (before leaving for London, albeit just a lip peck). Rachel - mentioned in this entry already.Shadow5
