Young "Game of Thrones" Star Takes Cinnamon Challenge!

Arya Stark is taking on a foe more dastardly than the vile King Joffrey: A tablespoon of cinnamon.

Following in the footsteps of Octomom, young "Game of Thrones" star Maisie Williams is the latest person to try the Cinnamon Challenge -- where people attempt to swallow a tablespoon of the spice while filming it to post on YouTube.

Note: toofab does not recommend trying this out at home!

Like those before her, Maisie fails miserably ... and ends up coughing it all out of her mouth.

Check out the video above.
