Trivia: Jennifer Aniston's actual last name is Anastassakis but her family changed it to Aniston when they moved to the United States. If you watch TOW Chandler and Monica's Wedding, Jennifer's actual last name is used for the Greek couple having their wedding in the episode.
Trivia: Matthew Perry and Bruce Willis starred together in the movie The Whole Nine Yards. While making the movie, Matthew made a bet with Bruce that the movie would open in the top position at the box office. If it did this (which it consequently did) Bruce had to star in an episode of Friends for no fee.Tallicame
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.
