Perhaps no TV show in history has enjoyed more memorable guest appearances from A-listers than Friends, which across its 236 episodes featured unforgettable roles for the likes of Brad Pitt, Bruce Willis, Danny DeVito and...Charlie Sheen.
But on the flip side, there are those actors who landed a small role on the show before they were particularly well known to audiences - if they were even known at all.
If you've given Friends a rewatch recently, you'll no doubt have been left stunned at the many actors who turned up on the show in their younger days, years before they hit it big in Hollywood and became a household name in their own right.
But there have been so many sneaky cameos and supporting players across Friends' 10 seasons that you'd be forgiven for forgetting some of them - especially those who hadn't yet won lucrative starring roles, received Oscar nominations and become known entities in the industry.
And so, looking at these now-famous names and faces, answer "yes" or "no" as to whether or not they ever made a guest appearance on the world's favourite sitcom...
