Corrected entry: Towards the start, when Chandler, Monica and Phoebe are listening through the walls, when they are listening to Rachel and Joey, and the camera slides "through" one room to another, you can see Phoebe's hand in front of the wall section that is in between the two rooms.
Corrected entry: In the scene where Phoebe is describing her worst Thanksgiving experience (in 1862 as a nurse) and her left hand is blown away, you can see that the hand is fake as it doesn't move, is shorter and is a different color to the right one. Additionally, in the time between the bomb exploding and her hand being torn away, a rope is visible moving it.
Corrected entry: In Rachel's hotel room, there is a door on the left of the wall that joins onto Monica and Chandler's room. Due to the layout of the rooms, the only place it could lead to is Monica and Chandler's room. However, when Ross is talking to Rachel and she's looking for Joey, she walks through this door and has a quick look around. Surely she would see Joey in there, or at least Monica, Chandler and Phoebe and ask if they knew where Joey was?
Corrected entry: In the scene where Monica and Chandler are about to get tested in the clinic, Monica says, "My tests are down the hall." But after she says, "I've got a vaginal exam to get to," she turns and walks the opposite way she of where she said her tests were.
Corrected entry: Matthew Perry was so famous for missing his mark while taping that he developed the backward slide that you see him do in almost every show. He would come bounding into his scene slide backwards looking down for his mark and then hit it. (Per the tour guide at Warner Brothers Studio).Boobra
Corrected entry: Chandler and Ross go back to the reception site to take pictures with disposable cameras to "replace" the cameras they had misplaced. Chandler is posing, smiling, etc. In the previous season, Chandler and Monica are getting their engagement picture taken and Chandler can't smile for the camera. In fact, Monica ends up taking her picture with Joey and puts that in the paper.
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.Pam-I-am
Corrected entry: In the flashback episode, Chandler and Monica are in the bar (which is soon to become Central Perk) and Rachel is in the same bar with her friends before she is due to marry Barry. When Chandler overhears Rachel - a complete stranger - say she wants one last fling, he tries to flirt with her, but she dismisses him. Monica then says "I know her" and talks to Rachel briefly with Chandler present.In fact, as revealed in later episodes, Chandler and Rachel knew each other when he was in college with Ross and Rachel was in high school with Monica - in fact they even made out at a college party.
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.
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?
