The latest stop on Kerry Washington's 'Scandal' promo tour? 'The Tonight Show,' where she faced off against Jimmy Fallon in an intensely hilarious game of Box of Lies.

Although Kerry is known for playing Olivia Pope, a no-nonsense character, the actress couldn't hold back her laughter as she and Jimmy tried to trick each other.

Of course, one of the best parts of the game is hearing the players create fictional descriptions for the contents of their boxes. Jimmy outdid himself, describing his object as "An iPhone 6 -- " ("Plus or regular?" Kerry interjected.) "... Plus. With a figurine getting a tattoo from another figurine that I believe to be Justin Bieber."

Yep, we'd be cracking up too. And while there's no doubt that Kerry is a good actress, is she good enough to win this game of Box of Lies? You'll have to watch the video above to find out!
