Friends is consistently rated as the most popular TV sitcom of all time for one major reason above all others - the iconic stature of the six central cast members.
The witty writing wouldn't matter much without the note-perfect performances of the six New Yorkers who audiences grew alongside over the course of ten seasons and 236 episodes.
But that's not to ignore the significant contributions of the wider supporting cast too, and especially those memorable characters who showed up for just a small stint - or perhaps even a single episode.
Though we might not always appreciate it, these characters comprise a large part of the show's social fabric, and without them Friends would feel a little, well, empty.
And so, just how well do you really remember those minor characters who nevertheless left quite an impression on many fans? From just a single image, can you pick the correct name from our multiple choice selections?
Consider taking a second glance over the options before picking your answers, because they might not be quite as obvious as they first appear.
But fear not no matter how you do, because the answers are at the end as ever. Good luck!
