Of all the one-on-one pairings in Friends, there are few more ripe for comedy than Ross Geller and Chandler Bing - perhaps only Chandler and Joey Tribbiani, if we're being honest.
The long-time best friends have always been there for one another, but also relished ripping each other a new one whenever the time has called for it.
Ross and Chandler got up to their fair share of hilarious and embarrassing shenanigans over the course of 10 seasons and 236 episodes, but how much of it do you still remember? And more to the point, can you recall exactly who did what?
Can you separate Ross' most absurdly neurotic episodes from Chandler's most toe-curlingly awkward encounters? Furthermore, can you remember those times that Ross and Chandler both did the thing?
You'll need a frankly encyclopaedic knowledge of the two friends' experiences throughout the show to get anywhere close to 100% on this quiz, and of course remember that the answers may not be as simple as they first seem.
But fear not no matter how you do, because the answers are at the end as ever. Good luck!
