Kerry Washington struggled to keep a straight face as she sat opposite Jimmy Fallon for a game of Box of Lies on Tuesday, Sept. 23.

The hilarious game is a recurring segment on Fallon's Tonight Show, where guests and Fallon himself have to tell their opponent what's in their box and be judged for their truthfulness.

Mom-of one Washington, who opted to tell the truth for her first go, got a fit of the giggles as she honestly proclaimed to Fallon that she had a pumpkin in front of her, full of spaghetti.

And the Scandal star proved herself to be a good interrogator as she picked apart Fallon's lie when he later tried to deceive her.

Previous players of Fallon's comic game have include Kate Hudson and Jennifer Lawrence.
