Buffy the Vampire Slayer may have wrapped up its seven-season run 17 years ago this May, but its influence on pop-culture - and especially the fantasy genre - is still felt widely today.
As ground-breaking as it was entertaining, Buffy was of course the campy brainchild of Joss Whedon, and even during its rougher seasons, won itself a loyal legion of devoted fans.
But if you haven't revisited the show in recent years, you might come a little unstuck on our ludicrously challenging Buffy quiz, which will test your fandom to its fullest, most ridiculous extent.
How well do you remember those crucial, series-defining moments in the show's first season? Can you name perhaps the most iconic episode in the series' history? And what about some esoteric nuggets of trivia most fans have long forgotten?
Only the most die-hard Buffy fans have even the faintest hope of racking up 100%. But the answers are at the end as always if you do get stumped, so good luck!
