The One Where Chandler Can't Remember Which Sister - S3-E11
Corrected entry: When Rachel is eating at the diner and she and Monica are talking, there is a red glass sitting in front of her. In the next shot she is talking to Mark and says "It's not funny!" and the glass is gone; in the shot after that it's back again.
The One That Could Have Been, part 1 - S6-E15
Corrected entry: When Rachael meets Ross at the magazine stand, Ross's "Busty Ladies" doesn't appear in his hand until Rachael points it out. At several points, both his hands are in view.
Correction: I have studied this scene very well and every time that Ross' hands are in view, you can see the magazine, "Busty Ladies", in his hands.
Corrected entry: In an episode shortly after Rachel and Ross break up, Rachel makes reference to the fact that she is like Kip, yet she would never have met Kip because by the time she joined the group, Joey was already Chandler's roommate.
Correction: She could have heard the others talk about Kip, and compared herself to the mental image she had of this (to her) unknown person.
The One After the Superbowl, part 2 - S2-E13
Corrected entry: Monica and Rachel have two fights in this episode - one before Monica's date with Van Damme, and then after. Interestingly enough, Monica, Rachel and Phoebe are wearing exactly the same outfits for both scenes, which seems just a tad unrealistic given that the date has taken place in between.
The One With Rachel's Going Away Party - S10-E16
Corrected entry: When packing up the spare room in Monica and Chandler's apartment, the boys find a pair of fluffy handcuffs in the wardrobe. Monica and Chandler painted the room and inside the wardrobe when Rachel moved out; wouldn't they have found them then?
The One With The Triplets - S5-E3
Corrected entry: Monica tells Chandler she is not going to go on the date with the man nurse. As she is walking away, Chandler is going to do a dance and she says don't do the dance. The dance she is referring to is the one he does where he hears that Monica is with someone who is the best sex she's ever had. How can she know about this dance if the first time she sees it isn't until the following episode?
Correction: Easy - Chandler probably does this dance all the time, and she knows him well enough to know that he does it when he wants to celebrate something.
The One Where Rachel Tells... - S8-E3
Corrected entry: In the scene where Phoebe and Joey figure out that Monica took away their keys, Phoebe had gotten a drink out of the fridge and set it down in front of her. In the next shot it is in front of Joey.
The One With The Red Sweater - S8-E2
Corrected entry: When Rachel walks up to Tag's table, she sets her purse on it. It stays there for a couple of shots, and then she sets it down again.
The One with the Candy Hearts - S1-E14
Corrected entry: Just before Ross crushes the egg on Chandler's back, you can see that he has nothing in either of his hands. You can see Ross shaking his fingers as he says 'she said yes' (00:02:55)
The One with the Boobies - S1-E13
Corrected entry: In the coffee house when Joey's dad asks Ross "How's the wife?" he moves his head and makes a groaning sound. His lips do not visibly move, and there is no other indication that he made this noise. It also sounds strange and misplaced in the shot if you listen to it in surround sound, implying it was dubbed in afterwards. (00:04:10)
Corrected entry: In early seasons in Chandler and Joey's apartment, there is a shelf between the fridge and the wall. In later seasons the shelf has disapeared and the whole kitchen has shifted so the fridge is against the wall.
The One with the Candy Hearts - S1-E14
Corrected entry: The English subtitles on the DVD show Carol's last name is Willet - but it's Willick. (00:05:15)
Correction: Subtitle mistakes on the dvd are not mistakes made by the show. They are DVD production mistakes.
The One With Phoebe's Wedding - S10-E12
Corrected entry: At the end when Ross is trying to get the dog to go to the bathroom, you can see the shadow of the trainer of the dog over the ground, getting the dog to run around everywhere.
The One With The Birth Mother - S10-E9
Corrected entry: Joey can read Phoebe's mind! Joey asks for the phone number of Phoebe's friend. Phoebe gives Joey a pen. He writes the name of the girlfriend on his hand and gives the pen back. Phoebe never tells him the phone number. A couple of scenes later, Joey is having dinner with that girl.
The One With the Male Nanny - S9-E6
Corrected entry: When Joey and Sandy are playing the recorders, the sound produced is out of sync with the finger movements, indicating that they are not actually playing the instruments.
Correction: No, their finger movements match the sound completely.
The One With The Embryos - S4-E12
Corrected entry: During the guys' lightning round, when they give an incorrect answer they are given a new question. The girls however have to keep guessing at what Chandler's job is, even though Rachel has given an incorrect answer.
The One After Joey And Rachel Kiss - S10-E1
Corrected entry: When Phoebe tells Monica and Chandler that Rachel and Joey are kissing in the next room, at the time she says "It's Rachel and Joey.", you can see that the door leading to their room has been partially cut to achieve the effect of the camera going through the wall. (00:01:40)
The One Where They're Going To PARTY! - S4-E9
Corrected entry: When Monica and Phoebe show the others the van, they are all standing on the curb. There is then a close up of Ross saying something and back to the wide shot. But now, Ross is standing in the road without having taken a step forward.
Correction: When Rachel and Mark are talking, Monica picks up a pitcher of water and you can see her reach for Rachel's glass. So, she is refilling it, that's why it's not there for a while.
