Nothing gets by the eagle eyed folk of the Internet, we all know this by now. That means that no TV show, however well-loved and revered, is safe. Now, fans reckon they've spotted something pretty funny - although absolutely not intended to be - in Game of Thrones.
When you have a look at the short video, you'll notice Nikolai Coster-Waldau walking across screen as Jaime Lannister in what was the first ever episode of the show.
Unfortunately, behind him a guy walks across the screen who looks less like he is in a strange medieval fantasy land and more like he's going down to the shops here in the 21st century.
As pointed out by the spotter, it looks like he is wearing a jacket made by Patagonia, a pair of blue denim jeans, and some boots. Hardly the fantasy world clothes we've come to expect.
Let's be fair here - when the very first episode was aired, HBO producers probably didn't quite realise they were going to have such a huge hit on their hands.
We know that the budget wouldn't have been the same - in fact, the budget would have been loads less, if what we're being told about the upcoming battle in the eighth and final season is anywhere close to being true.

Of course, there is always the chance that this is all an elaborate ploy from the show's creators and the whole thing is building up to a time-travelling reveal.
That would certainly get people talking. Like when The Sopranos just - well - ended, and that was that. Except this time it'll involve a time-traveller from 2019 in Britain sitting on the Iron Throne, having killed everyone else.
Oh, and some people have also noticed that he looks like a familiar face. There are a group of people out there suggesting that the modern/medieval man is - in actual fact - Bucky Barnes from the Marvel Cinematic Universe.
Yes, The Winter Soldier in Westeros. Stranger things have happened, right?
What do you mean, no?
The Winter Soldier was played in the MCU by Sebastian Stan, and he's not credited as having been in Game of Thrones, but it would certainly be a plot twist if he tipped out to end the war.
More likely than all of this is that it's all just a mistake and the guy simply looks a bit out of place. They didn't have the kind of budget to create huge outfits and CGI dragons and the likes back then.
Oh, and it's a fantasy kingdom - maybe they just wear Patagonia jackets, jeans, and boots. We're willing to believe in dragons and magic but that's out of reach? Come on, guys.
