Corrected entry: When Phoebe and Chandler are about to kiss there is a bottle of wine and two glasses on the counter. It then cuts to a view of Phoebe with no bottle or glasses on the counter, just a phone, and then later in the same scene it cuts back to Phoebe again and there are two glasses and a bottle of wine again.

Corrected entry: In the scene where Chandler pours Joey a glass of orange juice, even though there are sounds of something being poured, if you observe carefully, you can see that there is nothing in the glass - when the juice is supposedly being poured, and even when Joey is drinking the juice.

Corrected entry: In 3-7 Phoebe mentions that she can't say "croissants" and then does so perfectly. In this episode she is fluent. She had mentioned in yet another episode that she learned it while living on the streets and met friends behind a dumpster to learn it, so it's not she learned between episodes.MovieFan612
Corrected entry: When Ross and Joey are auditioning for Monica's maid of honour, Rachel says she met Monica when they were 6 and she met Chandler when he was 25, but in other episodes it shows that they had been to thanksgiving dinners together when Chandler was in college with Ross. In another episode it also shows Chandler and Rachel making out at a party, so she had met him plenty of times before he was 25.
Corrected entry: When Monica and Ross are discussing why they are not allowed to play football, Monica states in the story that they were both 6. This would imply they are either twins or at least the same age. However, we see that Ross is in fact older than Monica. Also, later in the scene Monica and Ross say the football incident occurred 12 years ago. This would mean that they are both currently 18 years old which is false. In one episode earlier in the season Monica states that she is 28 years old. (00:02:20 - 00:04:10)
Corrected entry: Monica tells the guys that she and Phoebe will search the third and fourth floors for the monkey and the guys would search the first and second floors. But Monica and Phoebe knock on Mr. Heckles' door, #9, which would be on one of the lower floors.MovieFan612
Corrected entry: Across the whole show, the infamous wall in Rachel's room / guest room (Monica's apartment) changes. When the room is not being filmed, the wall is as normal, but on quite a few episodes, when the room is actually used for scenes, the wall is much shorter. In both the episode where Ross buys Phoebe a bike, and where Phoebe and Rachel have to live with Monica after their apartment caught on fire, people are able to walk straight into the room without the wall being in the way.
