First she took on Ellen DeGeneres in a push-up contest.
Then she challenged Jimmy Fallon to a multi-"sport" competition where she emerged the "victor" as Bo, the first canine, looked on.
Say what you will about Michelle Obama, but she's on the money when she says that she's willing to make a fool of herself in order to promote the notion that Americans, specifically children, should put down their iPods and smart phones, get off their butts and start moving.
Her Let's Move initiative is noble and she's willing to go to bat for it. Literally. In the process of promoting a universally respected ideal -- that kids should exercise -- Obama is also attempting to smash the stodgy, stuffy, tea-and-crumpets stereotype of what an American first lady should be. And that is a very good thing.
