The video was in response to a President Barack Obama impersonator, Alphacat, who asked the First Lady via Vine: "How many calories do you burn every time you 'turn up'?! #AskTheFirstLady #LetsMove."
She responded: "Hey, Alphacat. The First Lady wants to know… #TurnipForWhat ? #AskTheFirstLady #TD4W."
Though Michelle didn't exactly answer the question, she did make turnips look cool.
This wouldn't be the first time the First Lady has promoted healthy living in a humorous way. Back in February, Michelle showed up on the "Ew!" show with host Sara (no "h") -- a.k.a. Tonight Show host Jimmy Fallon dressed as a tween girl -- to talk kale chips and exercise.
