VIDEO : Viola Davis Plays 'Best Friends Challenge' With Jimmy Fallon

Jimmy Fallon and Viola Davis played a friendly game of "best friends box" on Wednesday. Davis picked out a question first, asking Fallon what his superpower would be if he were a superhero. Fallon chose flying. Davis got a little more creative; "the ability to change my underwear without touching them." Next up, Fallon tried to guess Davis' favorite Christmas movie. Davis had to try to figure out what Fallon's name would be if he were a girl. Fallon chose the name Jim-aica. Davis' response. "I'm just going to say it. That's a black girl's name."
