At this stage it’s probably quicker to name the people who haven’t been given a cameo in The Simpsons than to list those who have.
In fact, they’re so widespread that you’ve probably featured in one of the episodes without even knowing it. Yes, you specifically, the person reading this sentence right now.
To our knowledge, there’s only one person who has been ruled out of appearing on the show as a guest - President Donald Trump - but the list of big names to get involved grew once more this week.
Game of Thrones star Nikolaj Coster-Waldau featured in the Season 29 premiere of the long-running animation, and it was a real blink-and-you’ll-miss-it job.
The season premiere transported the regular characters to a GoT-style setting as ‘The Serfsons’, so the involvement of the Danish actor isn’t that big a stretch.
A little while back we were told Coster-Waldau, who plays Jaime Lannister in the prestige HBO show, would feature in The Simpsons as “a character not unlike Jaime”.
“He has a surprising and sexy connection to one of the main characters,” The Simpsons’ executive producer Matt Selman told Entertainment Weekly over the summer.
The cameo might be a small one, but it is a clear nod to Jaime and Cersei’s relationship, through the obvious medium of…Marge and her twin.
And here’s Coster-Waldau himself, posing alongside his alter ego. Or should that be his alter-alter-ego?
Now, some will claim The Simpsons should have ended long ago, while others are airing their frustrations at the progress (or lack thereof) in the Game of Thrones universe, but we’re sure this easter egg will have pleased a few fans of both shows.
And that suggestion that America’s favourite cartoon family might disappear from our screens? The most-viewed episode in Season 28 still attracted more viewers than any episode in Game of Thrones’ first five seasons.
Things have changed recently, though, with even the least-watched episode of Game of Thrones Season 7 being viewed by 9.25 million people in the United States. The last time any episode of The Simpsons hit that mark was January 2015.
As well as including Coster-Waldau, the Season 29 premiere also slipped in a number of other Game of Thrones references, including putting Ned Flanders’ head up on a spike, a la Ned Stark.
And also giving us a very Westerosi twist on the classic Bart prank calling Moe gag, by having Bart send a raven instead of call the bartender up.
Game of Thrones will return for real for its eighth and final season… oh, I don’t know, any time in the next five years. The Simpsons will probably still be running.
