'Game of Thrones' star Nikolaj Coster-Waldau had the PERFECT 'Simpsons' cameo

The Simpsons used its Season 29 premiere to pay homage to the cultural phenomenon of Game of Thrones -- and they decided to make it extra authentic with a cameo from Jaime Lannister himself, Nikolaj Coster-Waldau.

Executive producer Matt Selman told EW that Coster-Waldau would be playing "a character not unlike Jaime," with a "surprising and sexy connection to one of the main characters," and we had no idea how accurate that would be.

The Danish actor lends his voice to Marge Simpson's twin brother, who seems to be hoping for a Jaime and Cersei-esque development in their relationship when Marge's marriage to Homer hits a rough patch.

Coster-Waldau's cameo is pretty blink-and-you'll-miss-it (he only has two lines), but it's deployed with perfect timing.

And that's not the only Game of Thrones reference in the premiere, which also pays homage to other literary fantasy favorites like The Hobbit, Lord of the Rings and The Chronicles of Narnia.

Early on, a three-eyed raven flies into the "Serfson" family's window, and Marge promptly bonks it on the head to make a stew -- offering Maggie the beak as a pacifier.

Poor Ned Flanders suffers the same fate as Ned Stark, ending up as a head on a pike, while Marge's mother is bitten by an "Ice Walker," which begins turning her into a wight too. And the whole episode hinges on a showdown with a dragon, natch.

There are plenty more visual gags for hardcore fans -- a store in the town square is named "Victarion's Secret" -- referencing another one of Theon Greyjoy's uncles from George R. R. Martin's A Song of Ice and Fire novels, a character that the Game of Thrones showrunners chose not to adapt for the HBO series.

An animated version of Martin even makes an appearance, wearing a tongue-in-cheek posterboard declaring "the end is not nigh," referencing the long delays the author has faced in publishing the final two books in his series.

The show also has fun with Bart's penchant for prank-calling Moe the bartender, giving the joke a Westeros twist by having Bart and Milhouse send a raven instead.

The Simpsons airs Sundays at 8 p.m. on Fox.
