The One With Rachel's Crush - S4-E13
Continuity mistake: At the very start Ross says to Chandler, "People can hear you," and looks away. The camera cuts to Chandler and Ross is looking at him. (00:00:10)
The One With The Soap Opera Party - S9-E20
Revealing mistake: When on the roof for the party, the view of the city is obviously fake. (00:12:20)
The One With Five Steaks and an Eggplant - S2-E5
Continuity mistake: When Chandler picks up the phone, he says "Bob here" and Ross is sitting by the bar on the living room side. When the scene starts again after the credits, Ross is getting a drink out of the refrigerator. (00:01:00)
The One With The Tea Leaves - S8-E17
Continuity mistake: Throughout the entire first scene where Rachel is asking Chandler and Monica if they have seen Joey and he's in the bathroom, Chandler is sitting at the table and his blue cup constantly switches from being in his hand to on the table much too quickly to be real movement. At one point he even holds a piece of food which then disappears from his hand back on to the plate. (00:00:45)
The One Where Nana Dies Twice - S1-E8
Continuity mistake: When Ross falls into the grave he ends up with a massive mud patch on his knee. He turns over and it's gone. (00:14:30)
The One with Two Parts: Part 2 - S1-E17
Revealing mistake: In the scene where Phoebe goes to see Ursula at Riff's, Ursula goes to get Phoebe her birthday present. When she sits down, you can easily tell, by looking at all the people there, that the shot has been sped up. (00:15:10)
The One With Monica and Chandler's Wedding, Part 1 - S7-E23
Visible crew/equipment: At the very start after Monica says, "We're gonna have lunch at Mom's" when the camera switches to a wider shot look above Joey's head. You can see the boom mic track him across the stage. (00:00:25)
The One With All The Wedding Dresses - S4-E20
Continuity mistake: When Chandler tells Joey that he should go to a sleep clinic, Monica puts her coffee cup on the table, but then it reappears in her hands and disappears repeatedly. (00:02:00)
The One With The Hypnosis Tape - S3-E18
Continuity mistake: After Mrs Knight sits down with Phoebe's brother in Central Perk, keep an eye on the strap of her handbag. It starts over her shoulder, then moves around and changes position at least half a dozen times. (00:04:40)
The One Where They're Going To PARTY! - S4-E9
Revealing mistake: When Monica and Phoebe are in Central Perk, Phoebe is looking through the list of ideas that Monica has come up with for the use of Phoebe's van. If you look closely (most obvious just after Phoebe says "let's plan the wedding reception") you can see that every single page of the notebook Phoebe is holding has the same thing written on it, instead of lots of different ideas that Monica is meant to have had. (00:17:10)
The One With The Video Tape - S8-E4
Other mistake: In series 8, 'The One with the Videotape,' when they are watching Ross and Rachel on the TV and when Rachel (on the video) is discussing the invitations and how Monica didn't shut up about sending them, Chandler points at the TV and makes a kind-of confused face. A few minutes later, just before he says 'Did you do it on our invitations?' the same shot of him pointing and pulling a face comes up. (00:17:05)
The One The Morning After - S3-E16
Continuity mistake: Right before Ross and Rachel storm in, the girls show Joey how much their waxing stuff hurts. Phoebe starts putting the wax on Joey's inner arm, but then the shot changes and she is spreading in on the outer side. Also she slaps the strip on and the blue tab is hanging down off his arm, but then the shot changes again and it is on his arm with the other end of the strip hanging off the other side. (00:11:10)
The One with Two Parts: Part 2 - S1-E17
Continuity mistake: At the end of the scene where Phoebe goes to speak to Ursula, Ursula has some food on her fork. In the next shot it is gone. (00:16:10)
The One With Ross's Teeth - S6-E8
Continuity mistake: In the opening coffee house scene Ross is holding a red folder, then it disappears and then he has it again. (00:02:05)
The One With The Dollhouse - S3-E20
Continuity mistake: When Monica and Phoebe are looking at the dollhouse, Monica says "I don't want a ghost for the house." When she says this, the camera is behind Phoebe whose right hand is up in the air. The shot then changes to Phoebe from the front, and her hand has instantly gone to her lap. (00:04:40)
The One Where They All Turn Thirty - S7-E14
Continuity mistake: Rachel's birthday has always been in May, not February/March. (00:16:00)
The One With Ross's Grant - S10-E6
Continuity mistake: When Aisha Tyler and Greg Kinnear put one hand on Ross's face, they bring those hands together and they interlock fingers, then the camera changes positions and they interlock fingers again. (00:22:20)
The One With All The Rugby - S4-E15
Factual error: Before Ross goes out to play the second half of the rugby game, Emily gives him some tips on how to hurt the other guys. She singles out one of the guys, saying he doesn't wear a cup. These guys are all English players who love rugby. Rugby players would NEVER wear a cup for rugby is more of a grinding sport than hit and miss. These guys would be crazy to wear a cup.
The One With Rachel's Other Sister - S9-E8
Revealing mistake: When Chandler grabs his bag he accidentally lets the box full of wedding china fall off the stool. Watch closely (play in slow-motion). The box falls on the floor and shattered china falls out. The china was ALREADY broken before it falls on the ground. (00:23:00)
Suggested correction: Slow-mo is not permitted under this site's rules.
The One With The Princess Leia Fantasy - S3-E1
Continuity mistake: When Ross and Rachel are arguing about Rachel telling Phoebe about his fantasy, Ross takes a popsicle out of the freezer and bites it. In the next shot, the popsicle is whole again, with no bites, and Ross takes another 'first' bite out of it. (00:11:30)
