Watch Kerry Washington Call Jimmy Fallon’s Bluffs on the Tonight Show

Last night, Kerry Washington dropped by the Tonight Show and joined Jimmy Fallon for a recurring segment called “Box of Lies.” It’s a game that requires contestants to guess whether or not the other player is lying about the contents of various boxes chosen at random. (Previous contestants include Jennifer Lawrence and Tina Fey.)

The Scandal star turned out to be pretty good at this game and totally ended up besting Fallon — though neither of them are any good at keeping a straight face or stifling their giggles.
