We've all been singing the 'Friends' theme tune wrong this entire time

Thanks to Netflix, millennials are getting a taste of what got us 90's kids through the decade: Rachel, Joey, Chandler, Monica, Ross and Phoebe. The hit sitcom Friends, which has proved to be a one-stop shop for nostalgia, is keeping a new generation of fans entertained with tales of love, heartbreak, financial ruin, and above all: sartorial mishaps.

One thing is for sure, however – millennials will be even more disturbed by the fact that six friends in relatively low-paying jobs managed to afford such a spacious abode in one of the most expensive cities in the world. I mean, I sure know what I'm blaming all my unrealistic expectations of adulthood on...

However, what will surprise fans of the television show most is that we've apparently been singing the theme tune wrong, this entire time.

The shocking news was revealed on Saturday's episode of ITV's Ant & Dec's Saturday Night Takeaway, as Declan Donnelly and his co-hosts Stephen Mulhern and Scarlett Moffatt took the show to the Universal Resort in Florida for this season's finale.

While they were in the "sunshine state", they entertained us with The Rembrandts, who are perhaps best known for their hit single, I'll Be There For You - which featured as Friends' theme tune for all 10 seasons.

Although we've heard the song countless times thanks to Comedy Central and Netflix, it appears that we've been singing it incorrectly this whole time.

One woman found this out the hard way when she was taking part in the Singalong Live segment. She ended up missing out on the grand prize after singing, "When the rain begins to fall", and not the correct lyrics, which are apparently "When the rain begins to pour". Who knew, eh?

Now, if you claim to be an avid Friends fan and are super disappointed that you misheard the lyrics to a song that you've literally heard millions of timesrest assured that the majority of the internet were just as baffled.

"I can’t believe I’ve been singing the theme tune to Friends wrong for the past 20 years! Who knew it was Pour and not FALL??!," one Twitter user wrote in complete disbelief. Another individual corroborated, "Who knew that the word was POUR and not fall??!! That’s 20 years I’ve been singing 'when the rain starts to fall' Gutted."

And a third chimed in, writing "still cant accept its 'when the rain starts to POUR' and not fall, my whole life is a lie, can never watch friends again".

Some Twitter users went so far as to claim that the whole thing was a conspiracy theory, and could be an example of the Mandela Effect in practice - for those that are unfamiliar, the "Mandela Effect" or a false memory is a psychological phenomenon where a group of people recall something that did not actually happen.

Well, I don't know about you - but, personally, I really don't know what to believe anymore...
