As reported on 20 September 2019: When Friends finally dropped on Netflix UK, many people began watching it again in earnest. And, during one binge-watching session, Aine Maloney noticed that Phoebe had somehow managed to be in two places at once.

The scene in question comes from the show’s very first episode, and sees Phoebe declaring that she had “just pulled out four eyelashes” – much to the bemusement of those around her.

However, as Maloney points out to Her, Phoebe can also be seen sipping a cup of coffee behind Monica’s date Paul, and seems to actually be listening to her telling everyone about her eyelashes.

Maybe it’s best to pretend that her twin sister Ursula had just popped over for a brief chinwag, eh?

The one where they changed Monica

Remember when Monica mysteriously transformed into someone completely different? We do.

In the episode, Phoebe (Lisa Kudrow) can be seen sitting on the Central Perk sofa with Courteney Cox’s character; the pair are chatting, laughing, and sipping on ginormous cups of coffee. So far, so normal.

Only, all of a sudden, the camera changes angle – and a woman that is clearly NOT Cox is sat in her place.
