Rick and Morty's post-credits Game of Thrones ‘jab’ was a surprise to its creators (update)

Rick and Morty co-creator Justin Roiland wants people to know he’s not harboring any ill will toward Game of Thrones after last night’s episode appeared to suggest otherwise.

After Sunday’s new Rick and Morty episode, an “in memoriam” card appeared which read “The Writing on Game of Thrones [2011-2016].” The apparent dig at HBO’s enormously popular show was caught by a few eagle-eyed fans, some of whom believed that the Game of Thrones jab was the product of Roiland and fellow co-creator Dan Harmon’s comedy.

But Roiland confirmed on Twitter today that he had nothing to do with the bumper. His statement was echoed by the official Rick and Morty Twitter account. Harmon, who is currently taking a brief break from Twitter, did not comment on the bumper.

An Adult Swim representative confirmed to Polygon that it was a member of the Adult Swim team that created the bumper, tagging it on to the end of Rick and Morty.

The chirp in question drew cheers and hollers from fans online, who took screenshots of the bumper and tweeted it with appropriate accompanying emoji. It may seem a bit nasty to include the card, but Game of Thrones’ writing and pacing has been a point of contention for many this season.

Like Game of Thrones, Rick and Morty won’t return for a new episode next Sunday. Unlike Game of Thrones, however, fans of Rick and Morty will only have to wait an additional week for a new episode.

Rick and Morty will return on Sept. 10 at 11:30 p.m. ET on Adult Swim.

Update: Co-creator Dan Harmon used Instagram to address concerns fans had over the bumper attached to Rick and Morty’s newest episode. Like fellow co-creator Justin Roiland, Harmon said he had no idea Adult Swim was going to add it, adding that he loves Game of Thrones. Harmon’s full message can be read below.
