Perhaps even more than the hilarious video is Clarke's caption that has Game of Thrones fans in splits.
"I mean, JEEEZE, one pet of a dragon and he thinks he's one of them," she writes, referring to the scene in season 7, episode 5 where Jon Snow pets Drogon. The video itself appears to have been shot where the scene took place.
Following the caption are several joking hashtags, including the now iconic line, "You know nothing, Jon Snow."
Fans of the two actors, meanwhile, can't stop raving about the video. "I laughed so hard at this," writes one user on Instagram. "Ahahhahahahh I love him! More please!" says another.
