Picking your favourite Friends characters is like choosing between children - it's a near-impossible choice that nobody ever really wants to make.
But it's tough to deny that there was no better bond between characters than the indelible fan favourite bromance between Joey and Chandler.
The inseparable duo were collectively responsible for so many of the show's most entertaining moments, while also catching the brunt of their pals' catty one-liners.
But just how well do you really remember Joey and Chandler's life and times as separate people? More to the point, can you recall whether these choice lines were said to Joey or Chandler?
You'll need a frankly encyclopaedic knowledge of Friends' most cutting and hilarious dialogue to have a chance of getting anywhere close to 100% on this quiz.
And while we've included a few especially tricky quotes to try and trip you up, on the plus side at least it's only a 50/50 coin flip, right?
Yet fear not no matter how you do, because the answers are at the end as ever. Good luck!
