Corrected entry: In most episodes at any point in Joey's apartment, the amount of CDs in the CD rack keeps changing.
The One With The Cake - S10-E4
Corrected entry: When Monica Geller tries to get a rematch on the race, Chandler Bing says they left -- but no door sound was heard.
Correction: Just because you don't hear a door close doesn't mean it didn't. They were playing a game and cheering and carrying on so it is perfectly conceivable that people could leave without being noticed.
Plus they probably shut the door very quietly so no one would notice them leaving.
Corrected entry: In episode 8.15, Phoebe accepts saltwater taffy treats from Ross saying she has never eaten them before when in episode 2.23, she mentioned that her then boyfriend, Ryan, a guy who is in the navy, gave her saltwater taffy for playing her guitar because he didn't have any change.
Correction: That doesn't mean she ate it. I wouldn't eat a piece of candy some stranger put in my bag.
The One With All The Resolutions - S5-E11
Corrected entry: When Phoebe and Joey are arguing about Phoebe's guitar teaching lessons, Monica comes in between them and gets her picture taken with them. Who takes the picture? Monica, Joey and Phoebe are all in the picture, Ross is on his date, Rachel is out (she comes in just after the picture is taken) and Chandler isn't there either (he is on the phone to Monica when Rachel picks up the phone). So who did it? There is no furniture there for Monica to have put it high enough to get them all in if she'd set the timer, either.
Correction: Monica's apartment has an area of work top near the door and it also has a table the the right as you can see when rachel comes in singing bad bad leroy brown, she must set a timer set it up on the work top or table and then go and pose for the photo, there fore it wouldn't need anyone to take it.
The One Where Nana Dies Twice - S1-E8
Corrected entry: Rachel says to Chandler that she thought he was gay when she first met him, but then later he spent "Phoebe's entire birthday party staring at her breasts". In a later season, we find out that they kissed when Chandler was in college and Rachel in high school. Also. Phoebe has not had a birthday since Rachel and she met for the first time.
The One With The Lottery - S9-E18
Corrected entry: After Phoebe calls Ross "daddy", the camera goes to Ross and he can be seen laughing for a second before talking.
Correction: He is laughing because the situation is awkward - it's not a mistake.
Corrected entry: Rachel says, "I'm Kip", and Joey asks who Kip is. Rachel answers that Kip lived with Chandler before he did. How does Rachel know this? She was the last to move and had little contact with Monica between college and the pilot episode.
The One With The Engagement Picture - S7-E5
Corrected entry: During the scene where Rachel gets Tag's scarf out of his backpack and smells it, a coworker walks up. Rachel puts on the backpack to disguise what she was doing. The camera cuts away a few times and the final time she does not have the backpack on anymore.
Correction: If you watch carefully you see it all the time. Since she is wearing a black coat it's sometimes difficult to see, but the backpack is there and in the last scene she takes it off.
The One With Barry & Mindy's Wedding - S2-E24
Corrected entry: In this episode, when Ross and Rachel are at the wedding, there's a couple, "Mr. and Mrs. Weinberg" that approaches and tells Rachel that he's happy to see her and he hardly expected to see so much (because in that episode Rachel walks down the aisle with her butt showing). The lady is actually another extra from another episode, the one where Chandler quits. It's the same lady who goes and tells Chandler about their boss wanting to talk to him.
The One After the Superbowl, part 1 - S2-E12
Corrected entry: At the episode's end, the kids from the library song hour all somehow manage to show up as a group to her coffee shop. But their parents are nowhere to be seen. So, what then - did upwards of a dozen kids, less than 10 years old, all independently call each other, when they only know each other through story hour, and arrange to go to the coffee shop together? What did they do with their parents? Or did they supposedly all bolt from the story hour together, without a single parent following? (00:21:00)
Correction: Some of them are sitting on grown-up's laps as Phoebe sings so some parents probably came with them. The parents who didn't object to the songs could have arranged for some of the children to go together.
The One With The Embryos - S4-E12
Corrected entry: For the game, there are 16 questions - 8 for each gender. When Ross says they have a tie, there are about 5 questions left on the board. Ross then goes to the Lightning Round and completely forgets about the other 5 questions. (00:07:30)
Correction: Ross says from the start that each team will answer ten questions. Ross has just made up more, in case one category is more popular than the others.
Corrected entry: The guys on the Fooz-ball table changes color during the show.
Corrected entry: When Ross is climbing up the fire escape and reading Rachel's 'pro list' to her, it is raining really badly. However, when the other four friends walk into the apartment, they are all dry.
Correction: Of course they are dry. If you look closer, you can see they are all holding umbrellas.
The One With The Hypnosis Tape - S3-E18
Corrected entry: When Monica shows Chandler the check from Pete, Chandler says, "Pete Becker, Pete," and he grabs a magazine from his briefcase, but before this Chandler told the girls that he hasn't been able to unlock the briefcase and he just carries it around, so how would Chandler have gotten it out?
The One With The Dirty Girl - S4-E6
Corrected entry: When Ross is kissing the dirty girl on her sofa, he calls her Sarah. Then, when he kills the rat on her coffee table and thinks it was her hamster, he calls her Shelley.
Correction: Actually, he calls her Cheryl both times, which is the correct name of the character played by Rebecca Romijn.
The One Where Underdog Gets Away - S1-E9
Corrected entry: In this episode, when Chandler is telling Rachel his Thanksgiving story, he says that he had just had a mouthful of pumpkin pie when his parents told him they were getting divorced. However, in 'The One With All The Thanksgivings', in the flashback, Chandler is eating turkey when they tell him (hence the houseboy saying 'more turkey Mr. Chandler?').
Corrected entry: In the airport Ross says "I really thought she'd stay". After he says this when the camera zooms out the cut between the carpet and the set floor is very visible. (00:19:50)
Correction: This is not a mistake; terminals are set up this way, carpeted at the gate and tiled in the walkways.
The One With Monica's Thunder - S7-E1
Corrected entry: From the start of Series 7 (and for the next 2 series' at least) does anyone else notice the change in Matthew Perry's voice? I've searched to see if anyone else has mentioned it and as far as I can tell, no one has, but to me it's very obvious. I'm not sure I can explain it too well, but there's just something in his voice that changed (the tone of it and overall sound); it sounds like a different person talking.
Correction: Matthew Perry stopped smoking during the run of the series. He apparently was a very heavy smoker. This most likely accounts for the change in his voice. In any case, this isn't a 'mistake' in the first place.
The One With The Worst Best Man Ever - S4-E22
Corrected entry: In the scene where Joey tells Ross that the stripper stole the wedding ring, when Chandler says, "So you might say, it's a magic ring", you can see Joey starts laughing in the background. In the next shot he starts laughing again. (00:12:30)
Corrected entry: In the scene when Phoebe gets back to the beach house, she is pouring herself a Margarita and instantly she goes from pouring it to holding it up.
Correction: How on earth is that a mistake?? My CD collection changed innumerable times over the course of 10 years.
