'Friends' fans notice something seriously weird in scene with Ross and Monica

The 90s sitcom Friends is perhaps the most loved television show in history. From the characters to the catchphrases to the theme song - there's very little that fans just don't adore about the six friends living in New York City.

The show's writing and acting lends itself to endless reruns and rewatching on Netflix, and the jokes just never get stale (I could listen to Ross shout, "MY SANDWICH?!" over and over again.) However, despite the fact the show came to an end 15 years ago (feel old yet?), many avid fans are only just noticing elements in the show that just feel... wrong.

Case in point, a scene in season 3, episode 25, titled 'The One At The Beach'. In this episode, the gang travels to Montauk to spend a few days at a flooded beach house so Phoebe can find a woman who she believes to be an old friend of her parents.

However, one evening the gang are left so bored, they decide to play a game of strip poker - but unable to find any playing cards, they play a game of 'Strip Happy Days Game' instead. And as the scenes progress, we see the gang all team up on Joey to get him naked, but we also see that Monica has lost her pants.

But fans have noticed something quite disturbing about this scene. Check it out and see if you can spot what it is:

And after 22 years, nobody had an issue with this scene - until now. Just think about that scene again for a moment; the friends playing Strip Happy Days Game. Joey, Phoebe, Chandler, Rachel, Ross and Monica playing Strip Happy Days Game. Phoebe, Chandler, Rachel, and brother and sister, Ross and Monica, playing Strip Happy Days Game.

Wait, what?

That's right, Ross and Monica - who are full brother and sister - decided to get drunk and play a stripping game together. Which is a little weird, I'm sure we can all agree.

In fact, many fans have turned to Twitter to express their discomfort at the scene:

Yes, that was a little reminder their that Monica was totally up for watching a sex tape that starred her brother.

Have you ever played a stripping game with a sibling? If the answer is 'Yes', we really don't want to hear from you.
