If you've ever binge-watched Friends - and we know you have, we've seen you - you'll have noticed something interesting. Something constant. Something that never really changed across the decade that Friends was on the air for.
We're talking about nipples.
There were a staggering amount of nipples in Friends. More nipples per square inch than any other sitcom of the 1990s. If you were to play 'drink when you see a nipple', you'd be out cold before you can say 'unagi'.
Look, here's Rachel's nipples
And here's Phoebe's nipples
And Monica's nipples
And Charlie's nipples
And some random woman's nipples
And another random woman's nipples
And in the interest of fairness, here's Joey's nipples
Aaaand Ross' dad's nipples
But, by far and away, there were more of Rachel's nipples than anyone else
It's never ending
