Game of Thrones' final season gave a whole new meaning to the term caffeine hit.
The wildly popular fantasy HBO series, which we farewelled in its eighth season in May, is one of the most expensively produced TV shows ever, making it all the more baffling when not one of its many production staff noticed a 21st century coffee cup was left in one of the scenes.
The disposable cup, which appeared in front of Emilia Clarke's character Daenerys Targaryen in the episode Winterfell, was glaringly obvious among millions of fans for being out of place among medieval candles and goblets.
The embarrassing error instantly turned into a trending story around the world and became the subject of many a hilarious meme.
And now, four months later, the series showrunners David Benioff and D.B. Weiss have finally broken their silence on the Starbucks bungle, referring to it as a "Persian rug" moment.
