Picking a favourite friendship pairing in Friends sure isn't easy, because the show did such a fantastic job of giving each of the six central characters time to hang out with each other.
But one of the more intriguing dynamics must surely be that of Rachel and Phoebe. While not as strictly iconic as the friendship between Rachel and Monica, the juxtaposition of Rachel and Phoebe's totally opposed backgrounds and personalities made for some easy laughs.
As both friends and roomies, Rachel's more buttoned-down personality bristled up against Phoebe's more oddball, free-spirited vibe, though inevitably some of Phoebe's quirks ended up rubbing off on her pal.
With that in mind, can you recall whether these memorable, even iconic moments were carried out by Rachel, Phoebe, or both of them?
You'll need an over-the-odds knowledge of the pair's life and times throughout the show, and as per usual, the answers aren't always as easy as they might at first seem, so have a think before making your choice.
But fear not no matter how you do, because the answers are at the end as ever. Good luck!
