Friends fans have been left scratching their heads after noticing a 'plot hole' in the backstory of Rachel Green.
Nearly two decades after it left our screens for good, Friends still remains many people's comfort show, with fans rewatching it on a regular basis.
The beloved comedy series ran from 1994 to 2004 and was one of the most-watched shows of its era, its millions of viewers closely following the lives of the six fictional pals for 10 years.
Not only that, but Friends well and truly thrust its main stars — David Schwimmer, Jennifer Aniston, Courteney Cox, Matt Le Blanc, Matthew Perry and Lisa Kudrow — into the limelight, changing their lives forever.
However, the one downfall of being one of the biggest shows ever broadcast (the finale was watched by 52.5 million people in the US) is that fans often pick up on continuity errors and so-called plot holes.
Most recently, fans have picked up on a detail about the backstory of Rachel Green (Aniston) that doesn't quite add up.
One eagled-eyed user on Reddit explained an error they had unearthed while rewatching the programme, specifically Season 5, Episode 7: 'The One Where Ross Moves In,' where Rachel tries to date a man named Danny, whom she nicknames ‘Yeti,’ and becomes convinced that he's trying to seduce her with mind games.
"In season five, Rachel’s flirting with a neighbour – he invites her to his moving in party but she plays hard to get and says she 'thinks she is going to be busy'.
"She says she is going to a 'regatta gala' (a boat race). He asks her if she sails and she said 'No.'"
Explaining the error, the user fast forwards to 'The One With Phoebe's Cookies' (Season 7, Episode 3).
"In season seven, Rachel teaches Joey how to sail because she had lessons when she was a teenager. So there it is. Thanks for reading. You can go back to your lives now."
It begs the question: can Rachel sail or not?
However, other users were quick to debunk the original poster's claims.
One person wrote: "Just because she can sail doesn’t mean she does at the time Danny asks. I can ride a bike, but if someone asked me if I cycle, I’d say no."
Others pointed out that they weren't that bothered by it, and that continuity was never particularly tight in the series anyway, with humour often taking the priority over accuracy.
Recently, the show's theme tune caused havoc on The Wheel when celebrity baker John Whaite was asked how many claps there are after the first line.
