Last night, the First Lady appeared on Late Night With Jimmy Fallon to promote her anti–childhood obesity campaign. It’s a worthy cause, but also a familiar one, at this point, so Michelle upped the entertainment factor by exploring the evolution of mom dancing with Fallon (who donned some very sensible drag for the segment). The medley includes old-school moves like “the go shopping, get groceries” and “the sprinkler” along with new favorites like the hands part of the “Single Ladies” dance and the Dougie, which our mom definitely cannot do.
