The One with Two Parts: Part 1 - S1-E16
Continuity mistake: When Chandler tries to fire Nina, he holds his left hand to his face. In the next shot he is holding his right hand up. (00:10:20)
The One with the Dozen Lasagnas - S1-E12
Continuity mistake: During the song at the beginning of the episode, keep your eye on Ross's mug. He is holding it in his lap, then there is a shot of Monica with Ross's empty saucer on the table. In the next shot, the mug has appeared on the saucer. (00:00:30)
The One With The Video Tape - S8-E4
Continuity mistake: At the end, Monica goes to dial a number, the camera changes and she has dialed with no time. (00:22:20)
The One with Mrs. Bing - S1-E11
Continuity mistake: When Joey asks Ross 'how could you let this happen' in the hall, his sleeves are down to his wrists. In the next shot, they are rolled up. (00:10:25)
The One Where Paul's The Man - S6-E22
Continuity mistake: When Monica is blaming Phoebe for Chandler hearing the wedding message, Phoebe puts the magazine down on her lap and it's closed, but in the next shot it's open. (00:15:40)
The One Where Chandler Doesn't Like Dogs - S7-E8
Revealing mistake: While Monica is sneaking the dog back to her apartment and Chandler is in the toilet, as Monica lifts her hand to her mouth she whispers, "Up!" to get the dog to stick its head out of the handbag. (00:15:00)
The One With The Truth About London - S7-E16
Continuity mistake: When Joey is reading his speech about all the giving and receiving, Chandler has his legs on the table at the coffee shop. You can see his shoes on the table when they show Joey, but when they change the shot to Chandler his legs are on the floor and crossed. (00:10:55)
The One With The Truth About London - S7-E16
Continuity mistake: In the flashback, Chandler says to Joey that he is watching a movie when the camera cuts to show the blank screen. In the reflection, you can see that there is no-one present in the room. (00:18:20)
The One With Phoebe's Birthday Dinner - S9-E5
Continuity mistake: Rachel is telling Ross why she doesn't want to go to the dinner, and she says "the first sign is I don't want to, and...I'm not going'. While she says this, her left hand is completely empty, but then in the next shot the camera goes back to Ross and she is now holding the baby monitor in that hand. It then moves around in different shots afterwards. (00:06:10)
Suggested correction: She comes in with that baby monitor and it never leaves the sight of camera.
The One With The Blind Dates - S9-E14
Continuity mistake: When Ross walks in to Joeys apartment and says "Hey you're not naked", the Magna Doodle pen is in the holder, yet when Rachel leaves it is hanging. (00:00:25)
The One With The Princess Leia Fantasy - S3-E1
Continuity mistake: Near the start when Janice is touching Joey's cheek in his apartment, Joey is seen from the front, and he is not holding anything in his hands. He is then shown from the side and he is holding a box of cookies or something similar. (00:02:25)
The One With All The Kissing - S5-E2
Factual error: When Monica is in the bath with Chandler, Joey comes in twice, forcing Monica to hide under the bubbles: first he asks Chandler if he wants some chicken, then again when Chandler calls him back and Chandler's giving Monica's order, with Monica still hidden under the bubbles. Somehow, Monica supposedly hears Chandler requesting a soda and nudges or pulls him or something to indicate he was going to get the wrong kind. But no way she could hear him under the water (stick your head in a tub and have your friend recite the alphabet, and see what I mean). (00:01:00)
The One Where No One's Ready - S3-E2
Other mistake: When Monica beeps into Richard's machine and changes the outgoing message, she always presses the same two buttons when trying to interact with his machine, but gets a different result each time. (00:19:00)
The One After the Superbowl, part 1 - S2-E12
Continuity mistake: When Phoebe gets the kids to sing along to 'That's another thing that you don't wanna do', there is a little boy and girl sitting perfectly still. The shot cuts to a close-up, and one of them is now standing and they are both swaying. (00:11:40)
The One With All The Resolutions - S5-E11
Continuity mistake: During the countdown to midnight, just as everyone says, "Happy New Year!", the camera cuts to Phoebe and Ross. In the background Joey and Rachel open their arms to hug each other; the camera cuts to just Joey and Rachel and they open their arms again. (00:01:00)
The One Where Chandler Crosses The Line - S4-E7
Continuity mistake: When Ross is telling Monica and Phoebe that he found his "sound" in college, Monica spits out her orange juice and places the glass on the coffee table. The shot changes to Phoebe and you can see Monica putting the glass down again. (00:03:30)
The One After the Superbowl, part 2 - S2-E13
Continuity mistake: When Susie is asking Chandler to wear her undies, her hand is on his neck. In the next shot it is gone, and then it is back again. (00:08:45)
The One Where Joey Dates Rachel - S8-E12
Factual error: The premise of Chandler filling the high score list with dirty words is not possible for this game. Ms. Pac-Man only keeps track of a single high score, which is always displayed at the top of the screen. Unlike many other games of the era, there is no screen showing a list of additional top scores alongside initials during the attract mode, and there is not even a mechanism for entering initials within the game's code.
The One With The Tiny T-Shirt - S3-E19
Audio problem: When Joey chants "Oh Mommy, Oh Daddy, I am a big ol' baddie" his voice doesn't match his lip movements.
The One With The Truth About London - S7-E16
Audio problem: During Rachel's scene sitting on the couch with Ben talking about her and Ross and her sisters, Rachel's mouth moves in any scene showing Ben, but without her being heard.
