NOT trying to boast or anything - but if we were to ever go on Mastermind, then Friends trivia would be our specialist subject.

We can easily rattle off all of Joey's many, many acting roles, Phoebe's selection of bonkers songs and the name of Chandler and Ross' college band - remember Way, No Way?

But one thing we've never noticed up until now is that Rachel wasn't just a few weeks overdue when she gave birth to Emma in season eight - but she was pregnant for an entire YEAR.

No wonder she was so fed up by the end of it.

..

After spotting the stark continuity error, one Reddit user and Friends superfan wrote on the : "In season seven, episode 17, The One With the Cheap Wedding Dress, Monica says she is getting married on May 15th."

In the first episode of season eight (still set during Monica's May wedding), Rachel confirms that she's a couple of weeks pregnant - however in The One with the Halloween Party, she STILL doesn't have a baby bump despite being five months pregnant.

The user continued: "In season 7 episode 24, The One with Chandler and Monica’s Wedding: Part 2, Joey says the release date for his World War 1 movie is Memorial Day weekend [27 May 2002].

"We find out in season 8 episode 22, The One Where Rachel is Late, that the week before his movie premiere is her due date."

Pointing out how Rachel's May due date is almost exactly one year on from Monica and Chandler's wedding, they concluded: "That would make her pregnant for 12 months."

Naturally, other fans on the forum were equally bothered by the inconsistencies and pointed out how the show made it seem like Emma was born during a sweltering hot New York summer.
