First Rick and Morty dropped by the My Little Pony universe, and now Game of Thrones has opened a portal. The HBO drama’s creators and star Peter Dinklage apparently contributed a commentary track to the infamous “Pickle Rick” episode, and you can hear the first clip right now.

Entertainment Weekly shared a first clip from the May 15 Blu-ray release, which features Peter Dinklage and Game of Thrones showrunners David Benioff and Dan Weiss calling one of the “Pickle Rick” scenes “maybe the best writing in 2017.” A later clip also sees Weiss mentioning that “The last episode of Game of Thrones should be a live-action version of Pickle Rick.” Watch the first clip below:

Rick and Morty creator Justin Roiland was apparently hinting at the collaboration in a photo tweeted last summer:

The two series have had amusing interaction before, as a brief cutaway clip from Rick and Morty’s famous “Interdimensional Cable” episode featured an alternate Game of Thrones wherein Peter Dinklage’s Tyrion was the tallest character in a cast of dwarves. Another more pointed interaction last year featured Adult Swim airing a bumper eulogizing the writing on Game of Thrones, though Roiland and co-creator Dan Harmon were quick to deny they had anything to do with it.

You can watch the clip above, stay tuned for more news on Rick and Morty’s future and pick up the Blu-ray for yourself on May 15.
