Wow. We’d heard a little bit about the first lady’s campaign against childhood obesity during President Obama’s first term, but most of the noise came from hungry kids who found their incredible shrinking school lunches coming up short. With four long years ahead, it looks like the “Let’s Move” campaign has found a second wind. Big Bird teamed up with Michelle Obama to shoot some PSAs, and now the cartoonish Jimmy Fallon is playing the puppet in “Evolution of Mom Dancing.”

How cool is that?

God, huh? Does anyone else hear “Let’s move” and think not of dancing but of packing their bags?

Next up: Jay Leno and Barack Obama perform “The Evolution of Mom Jeans.”
