Continuity mistake: When Rachel is talking to Phoebe about cremating the coat there is a mirror behind her with a laptop reflected in it. The reflection shows it switched on, but in the wider shots it is switched off. (00:09:15)
The One With Joey's Big Break - S5-E22
Continuity mistake: When Joey arrives in the desert there is a lot of stuff not in vans. As the director gets into his car, loads of equipment is still in the desert, but a few shots later the vans are full and leaving. (00:18:50)
The One With All The Thanksgivings - S5-E8
Visible crew/equipment: Monica is explaining her Thanksgiving to Chandler; when she drops the knife there is a shot looking up from the floor. A crew member's shadow is visible on the ceiling. (00:07:10)
The One With All The Kissing - S5-E2
Continuity mistake: There is a scene in Central Perk where Rachel confronts Chandler about all the kissing he's been doing. She raises her hands up in front of her and tells Chandler to hold on to stop him from getting up from the couch. As he goes to sit back down on the couch she lowers her hands to her lap. The shot cuts to an angle behind Rachel's chair and she is lowering her hands again. (00:14:35)
The One Where Rachel Smokes - S5-E18
Continuity mistake: Joey's snowcone changes during the scene with Ross at the party. It goes from rounded to more flat to rounded, and from plain ice to being able to see the flavoring to ice again. (00:20:00)
The One With The Triplets - S5-E3
Factual error: Joey always grabs his back when he gets his pain from his kidney stones. This is a classic referral pattern for pain when the stones are in the kidney. However, the doctor says that the kidney stones were too close to the bladder. Stones in the ureters classically refers the pain to the groin area. (00:02:40)
The One Where Everybody Finds Out - S5-E14
Continuity mistake: The amount of buttons undone on Pheobe's top by Joey changes after she says, "You didn't rip any buttons." The camera cuts to Joey then back, and it has changed. (00:18:00)
The One With Joey's Big Break - S5-E22
Other mistake: When Joey and Chandler are in the cab on the bridge, Joey quickly stops the cab so Chandler can get out. However, on the screen behind, the background doesn't 'slow down' as Joey does, it just continues as if the cab is going at the same speed. Then, in the next shot, it is still. When Joey sets off again, the background stays the same and doesn't show that the cab is getting faster. (00:13:05)
The One With All The Kissing - S5-E2
Continuity mistake: In the Central Perk scene where Rachel is telling Ross she loves him, Ross is sitting at the small round table. The blue cup and the white cup with the lid move positions throughout the scene. (00:16:25)
The One In Vegas, Part 2 - S5-E24
Continuity mistake: When Monica and Chandler find the dice under the craps table, it is at an angle so both the four and five appear up. When the camera changes to the last shot (the zoom in of them kissing) the dice is sitting flat on the floor. (00:33:35)
The One With Ross's Sandwich - S5-E9
Continuity mistake: In the second scene with Phoebe and Rachel in the night class, when the camera looks over Rachel's shoulder, she has "Jane Eyre" in her hand face up, but when the angle switches to front view, she has nearly placed the book on the desk. (00:13:20)
Continuity mistake: Rachel and Phoebe are in the Central Perk, talking about leaving the group, and a jacket and a handbag are hanging on the arm of the chair behind Rachel, slightly to her left. Between shots it changes from just the jacket, then just the handbag and so on. This continues throughout the scene when Ross comes in and Phoebe leaves. As she gets up you see both again, however Rachel does not move enough to just show one and hide the other. (00:16:00)
The One In Vegas, Part 2 - S5-E24
Continuity mistake: When Pheobe is telling the Lurker to go away her hand is in the cup of coins, an instant cut later and it's out with no time to do so. (00:29:00)
The One With All The Kissing - S5-E2
Continuity mistake: In the scene after Monica pretends to drop socks in the hallway in order to prevent Rachel from telling Ross she still loves him, Rachel goes back into the apartment and locks Monica out. Monica then starts to pound on the door with her bare left hand. The scene changes to the apartment and Ross opens the door to let Monica in. All of a sudden Monica is pounding the door with her right hand wrapped in a sock. (This continuity problem is for the widescreen version, where we see a closeup of Monica not seen on the DVD, in the hallway with a bare hand right before Ross opens the door. However, on the DVD there are extra shots of Ross and Rachel after seeing Monica's bare hand pounding and then seeing her with the sock on her hand, which gives her ample time to put it on). (00:11:45)
The One Where Ross Moves In - S5-E7
Continuity mistake: At the very start of the episode, when Joey's showing Chandler National Geographic, Chandler has his left hand up by his face in one shot, then when the angle changes they're both clasped in his lap. (00:00:05)
The One With The Inappropriate Sister - S5-E10
Continuity mistake: When Phoebe is being removed from her "bucket spot" she starts to take off the signs she has put up. With the camera close up to her, she rips one off, then the camera changes to a wide view, and she is suddenly holding two signs. (00:16:40)
The One With The Triplets - S5-E3
Continuity mistake: When Alice runs towards Frank in the waiting room, there are at least two people sitting on the couch next to Frank. Immediately afterward, when Frank and Alice lie down on the couch, kissing, these people have disappeared. (00:16:30)
The One With All The Resolutions - S5-E11
Continuity mistake: When Ross first enters Elizabeth's bathroom, the lotion is first in line on the shelf; next to it is something else and then the powder. Later, the powder is first in line on the shelf and the lotion has moved. (00:09:30 - 00:12:45)
The One With The Girl Who Hits Joey - S5-E15
Other mistake: When Ross and Phoebe are eating cheese puffs and party mix out of the bags, Phoebe's bag reads "Heez-I" instead of Cheez-It, and the brand "Sunshine" has been covered.
The One In Vegas, Part 1 - S5-E23
Visible crew/equipment: When Ross is leaving Rachel's, a stagelight can be seen by the bathroom. (00:12:00)
Answer: The statements that she's contradicting (that it is common, it happens to every guy, and it's not a big deal), are the things that a woman commonly says to a man who is suffering from erectile difficulty, typically to assuage his bruised ego. However, most men do not believe that these statements are true, as evidenced by Chandler's outburst. He's so caught up in the proof that women are lying about it that he gives himself away.
