When you've watched Friends a bajillion and one times, you start to notice weird or out-of-place things in the background of episodes...like when Matt LeBlanc was caught laughing on screen:
Or how Ross spelled Rachel's last name wrong on his wedding invitation:
Or the time the burglar who robbed Chandler and Joey left a note on the Magna Doodle that read, "Thanks for all your stuff!":
Or that extra who was seemingly chewing her coffee:
So we want to know what out-of-the-ordinary things you've noticed while watching Friends. It can be anything from continuity errors, to flubs, to just straight-up weird things you noticed in the background!
