Michelle Obama continued to celebrate another anniversary of her Let’s Move! campaign, this time on NBC’s The Tonight Show Starring Jimmy Fallon where last night she performed The Evolution of Mom Dancing, Part 2.

The First Lady and Fallon go way back; she first appeared on Late Night in 2012, joining Fallon in a comedy sketch to mark the second anniversary of the Let’s Move! anti-obesity initiative. She guested on his show again in February 2013 to mark the initiative’s third anniversary; that appearance was her first late-night since her husband got sworn in for a second term and her first sit-down with Fallon. The First Lady also was one of Fallon’s guests during his premiere week as host of Tonight Show, bringing with her a ratings bump compared to the previous night.

The Let’s Move! campaign was announced on February 9, 2010, geared to encourage healthier food in schools, better food labeling, and more physical activity for children.
