While David Schwimmer's Ross Geller may not be as appealingly chilled-out as Joey (Matt LeBlanc) nor as hilariously sarcastic as Chandler (Matthew Perry), his uniquely high-strung neurosis nevertheless makes him one of the most entertaining sitcom characters of all time.
And though not everything Ross did over Friends' 10 seasons has aged well - shaming the male nanny and enforcing masculine stereotypes upon his son, namely - he's unquestionably played host to some of the legendary sitcom's most iconic and unforgettable moments.
But with Friends having left our screens 16 years ago (!) this May, you'd be forgiven for being a little rusty on your knowledge...unless you've been relentlessly binging it on Netflix, that is.
And with that in mind, you'll need to be a major Ross enthusiast to get even close to 100% on this quiz, which will require an inside-out knowledge of his early life, personality, relationships, and yes, his weirdest quirks.
The answers are at the end as always, so good luck!
