Tatum, appearing to promote his film "Foxcatcher," and Fallon spent most of the segment staring each other down and making box-related jokes.
As for the game, they both correctly called each other out on lying about the contents of their first boxes (Tatum had a Chewbaca doll encased in gelatin, Fallon's contained a hot water bottle). The tie-breaker, then, came down to an E.T. doll in a sleeping bag that made Tatum lose it the second he opened the box.
