Corrected entry: In the party after the wedding Rachel's mom comes up to Rachel to talk. Well in one shot Rachel has her drink in her right hand right when her mom starts handing her drink to Rachel. Next shot Rachel has her drink in her left hand and takes her mom's in her right hand even though there's just no time to switch hands between those shots.
Corrected entry: In The One With All The Thanksgivings, Monica is cheering up Chandler by putting a turkey on her head. Where did the whole uncooked turkey come from though, considering they had just had their meal? Did Monica just happen to have a large turkey in her freezer? To make matters worse, it is not possible for a human being to put a frozen turkey over his head for that long and not faint.
Corrected entry: When Rachel comes in to spy on Ross through Monica and Chandler's window we hear the shower water running and both Monica and Chandler are in the bathroom. However, Chandler comes out wearing a T-shirt under his robe (and he's wearing socks). This seems to assume that he is dry (as the T-shirt is dry too). Also we can see that Monica is wearing her nightdress under her robe when we see down to her feet, so how could one or both of them have been showering?
Corrected entry: As Chandler is leaving for Tulsa, he tells Monica to have Geoffrey (who Monica claimed was the funniest person she ever met) email him with funny Oklahoma jokes at www.hahanotsomuch.com. There is a real web page with this name with various quotations from that episode.
Corrected entry: When the gang minus Rachel receives their invitations, Phoebe states that Ross let Ben address hers, and shows the rest of them. We see that the envelope has a full address consisting of four lines. Chandler then enters, and about 10 seconds later we see Phoebe's invitation again, this time only having an address consisting of one line.
Corrected entry: When the police officer is giving Rachel a ticket he sees her birthday, says "Aquarius", and she says yes. But in an earlier episode when Gunther is asking for people's birthdays Rachel says her birthday is May 5. To be an Aquarius your birthday has to be between January and February.
Corrected entry: Chandler claims to have hidden Joey's underwear because "he stole my essence." But Chandler didn't go out of the apartment to do this, meaning the only time he could have done it was when he was over there first, and he wouldn't have done because there was no incentive to do so as Joey hadn't taken the cushions off the chair.
Corrected entry: Ross already told his parents that Carol was a lesbian in Episode 1 "I told mom and dad last night, they seem to have taken it pretty well." But in the 2nd episode Ross tells his parents after dinner at Monica's like it was the first time he told them.
Corrected entry: In The One With Monica's Boots, Joey finds out that his younger sister Deena is pregnant. Joey then storms off to find her boyfriend Bobby and manages to find him. How would he be able to, though? It is made clear that Joey has never met Bobby before, therefore he would not know what he looks like or where to find him. Even if he did some how manage to find him how did he manage to do it so quickly?
Corrected entry: In the episode in Barbados (part 2) when Mike and Monica are playing table tennis, Mike goes to great pains to explain that if a player puts his/her non bat hand on the table while the ball is in play then the player forfeits the point. Just before Mike wins his game (the second game they play) he stretches to get a shot from Monica and places his non bat holding hand on the table.
