"It's Always Sunny in Philadelphia" mastermind Rob McElhenney tweeted a photo confirming that "Game of Thrones" head honchos D.B. Weiss and David Benioff, announcing that the writing duo penned an episode of the long-running comedy for its upcoming season.

"Game of Thrones" is clearly very different than "It's Always Sunny," which will premiere its ninth season on the newly-created FXX channel in the fall. Here's hoping for a Tyrion Lannister-fuelled makeover of Paddy's Pub, or at least a Charlie-Hodor bromance.

McElhenney is a big "Game of Thrones" fan, recently interviewing the cast of the HBO megahit at an event sponsored by the Academy of Television Arts & Sciences in Hollywood.
