On Thursday, Michelle Obama celebrated the third anniversary of her "Let's Move" campaign with a dancing event in Chicago. The FLOTUS and some other famous people like Serena Williams, Bo Jackson, Dominique Dawes, and Gabby Douglas hopped up on stage to do dances like "throwing it away," the "dribble," and the "step-together, step-together."

Another reason to break it down, Nike has agreed to give $50 million to a five-year expansion of "Let's Move."
