Do you know how to Dougie? Let Michelle Obama teach you! The first lady and Beyoncé made surprise visits to middle schools today (May 3) as part of the "Let's Move" campaign against childhood obesity. It was the official "dance-in" at middle schools nationwide, and, to celebrate, middle schoolers were treated to a dance to Beyoncé's new song for the campaign "Move Your Body." Two of those schools, Alice Deal Middle School in D.C. and PS 161 Pedro Albizu Campos in Harlem, received the extra-special guests. Watch the videos on Urban Daily and LA Times.
