Game Of Thrones is far from a humorless show, but Jon Snow’s storyline has him looking pretty dour most of the time–he’s got white walkers, demanding sovereigns, and having the hots for said sovereigns to worry about. Kit Harington takes it in stride, though, gamely offering a variety of confused and grim expressions that would look appropriate at any shocking revelation or massacre. But thanks to Sesame Street, Harington was able to show off a more playful side recently, telling the kind of joke we’re accustomed to seeing on old Laffy Taffy wrappers.

Harington was participating in Elmo’s “Share The Laughter” challenge while on a Thrones red carpet, which might have been why his delivery was a little flat, but it’s a solid nod to Sesame Street’s feathered residents. Still, he won’t be headlining any comedy shows in Westeros anytime soon.
