Let's be real, being a guest on The Tonight Show Starring Jimmy Fallon always seems like a super fun time so when Avengers: Age of Ultron star Scarlett Johansson stopped by yesterday, it truly did not dissapoint. 

The pixie beauty played a game of Box of Lies verses Jimmy Fallon and it was absolutely hilarious! Watch the Black Widow face off with the late-night host as they try to trick each other as to what is in their box. Warning: the video includes Gumby action figures, Starbucks cups, and diamond studded mannequins. Um....what? Okay trust us, it'll all make sense after you watch the clip!

Check out the game below and get ready to LOL!
