Why is Beyoncé dancing in the middle of an elementary school cafeteria you might ask? She officially teamed up with First Lady Michelle Obama and the National Association of Broadcasters Education Foundation for the "Let's Move! Flash Workout" campaign to help fight child obesity. And the best song to help combat that? A reworked version of her 2007 single "Get Me Bodied" off B'Day. Don't worry, there's a Spanish version too.
