Factual error: This mistake is from series 6 onwards, with Ross' new apartment: There is an impossibility with Ross' kitchen, but not all of the time. It depends on the layout of the hallway outside his apartment. If the hallway continues along for a bit before going left or right, then the kitchen should stick out. However, when the hallway is a dead end, the kitchen fits ok.

The One With The Apothecary Table - S6-E11
Visible crew/equipment: After Ross and Rachel cover the table with the sheet, when Phoebe walks in Rachel says they can turn out the lights and watch the movie, and in the next shot we can see the end of the set wall, the soundstage and a crew member's leg.
Trivia: Matthew Perry's wit is so legendary that the scriptwriters have often incorporated his gags into the show.
The One With The Dirty Girl - S4-E6
Question: When Joey asks why he can't give Kathy the pen, Chandler says, "Because she's not eleven. And it's not the seventh night of Chanukah." What is Chandler talking about when he says, "It's not the seventh night of Chanukah?"
Answer: Chanukah is a Jewish celebration that occurs around the same time as the Christian Christmas. The celebration lasts for eight days and it is customary to give a small gift on each of the eight days. There is no special gift required and the line about it being "the seventh night" of Chanukah is just Chandler's sarcasm.





Answer: Usually by the seventh night of Hanukkah you don't know what to get the other person, and you will probably resort to getting the other person something insignificant. Chandler is basically saying that the pen is a stupid gift.
