Now, thanks to Primark, we have the perfect attire to do it in.
Check out these super cosy twinning PJ sets, which are perfect for you and that special person in your life who's, well, the Monica to your Rachel.
On the top half, there's a snug pyjama tee emblazoned with the metallic slogan 'She's my Rachel Green' or, alternatively, 'She's My Monica Geller'.
On the bottom, there's polka dot pyjama trousers with ribbon drawstring detail and cuffs that ward off any chilly winter drafts.
Decked out in coordinated monochrome, the dotty PJs are the ideal winter purchase for you and your Friends-loving BFF.
Available in the UK, Europe and the US, the spotty sets cost £14, €16 and $18 respectively.
Primark's official Insta account shared a of the PJs alongside fresh pastries and coffee.
The caption read: "It's a day for :coffee: and #Friends re-runs! Tag the Monica to your Rachel below."
Elsewhere in the world of Friends-themed loungewear, we're very obsessed with these comfy 'Girls' slogan tees from Etsy, which look just like the ones worn by Monica and Rachel in the hit show.
Available in black, grey and white colourways, the tees cost just £13.59 each.
One five-star reviewer wrote: "Amazing! This was a gift for my best friend who is a lifelong Friends fan. She squealed when she opened the shirt. I got one for her daughter and myself as well."
While another commented: "Perfect fit!! I'm an xsmall! Snug but still stretchy! Soft not itchy at all! Loved it! Ordered both colors red & green!"
Anyone else ready to grab the Monica to their Rachel and settle in for a Friends marathon?
