A day after having Heidi Klum on The Tonight Show starring Jimmy Fallon, and rolling across the stage with her, Jimmy Fallon welcomed Julia Roberts to the show, and the two of them played "Face Balls". The goal of the game was to take two progressively larger beach balls and hit each other in the face, while being filmed with super slow mo cameras. As Julia Roberts said "It is the comedy version of 50 Shades of Gray!" Holy crap, wait till you see how hard Fallon threw the ball on his last turn! Julia Roberts was checking her teeth!
