When Moms (and First Ladies) Dance

The first lady, Michelle Obama, won rave reviews on Saturday for her dancing.

Mrs. Obama joined Jimmy Fallon, the host of NBC’s “Late Night,” on Friday for a video titled “Evolution of Mom Dancing.” Moves executed by Mr. Fallon, in a brown wig, and Mrs. Obama, included the “Pulp Fiction”; the “Just the Hands Part of ‘Single Ladies’” and the “Where’s Your Father (Get Him Back Here!).”

The appearance was “to encourage parents everywhere to get up and get moving with their kids,” according to a description posted with the video, and was linked to a campaign by Mrs. Obama, called “Let’s Move,” which encourages healthy eating and physical activity to figh obesity.

In a subsequent interview, Mrs. Obama said that she tried to embarrass her children on the dance floor “as often as possible.” Her husband, she said, fails to match her moves â€" a sentiment echoed among the praise posted on Twitter. “Michelle Obama can certainly dance better than the president,” said one viewer.
