Quarter of a century ago, six fresh-faced, floppy-haired twenty-somethings became friends. For the next ten years, television cameras captured all the ups, downs, and unbearably sarcastic comments from their time pal-ing together in their ludicrously unaffordable downtown Manhattan apartments.
NBC's hit sit-com - creatively titled 'Friends' - ran for ten seasons, making household names of its sextet or stars in the process. A creative and commercial juggernaut, the programme earned a mammoth 62 Primetime Emmy nominations, whilst consistently rating within the top ten most watched TV shows for each year of its run.
Things finally came to a close in 2004, with a finale witnessed by a mammoth 52 million bleary eyed Americans, at last saying goodbye to the greatest friends they'd never met.
Fifteen years on, those faces are a little less fresh and the hair's slightly lighter, but TV's finest ensemble cast remain just as close - and just as popular - as ever. According to an annual survey, Friends is still a favourite amongst youngsters, even though none of them were born when it ended, let alone started.
That all means that obsessive knowledge about the show is just as much a part of the current generation as it was the last. Did you see The One With The Super Hard Friends Quiz? Nope?
This is it.
