(CNN) -- Michelle Obama, never one to turn down an opportunity to champion healthy eating, has co-opted a popular tune -- and, in six seconds, created a viral sensation. Here's how it happened. In an #AskTheFirstLady segment, Barack Obama impersonator Imman Crosson, or @AlphaCat, asked Obama, "How many calories do you burn every time you 'turn up'?!" (That's lingo for ... well, in the safest sense, cutting loose). Her six-second response, posted on the White House Vine account? Well, just watch. Yes, that's the first lady dancing with a turnip. It's a take on DJ Snake and Lil Jon's "Turn Down for What." The result? Cool points, and a cool point made. Obama is known for her commitment to health, especially among children and young people. Her "Let's Move" campaign aims to "solve the epidemic of childhood obesity within a generation." So she's not entirely uncomfortable wielding a vegetable. This isn't her first foray into pop culture to get us to eat our veggies. Earlier this year, she starred in a "Tonight Show" skit called "Ew!" The first lady taught Sara, played by Jimmy Fallon, and Stacy, played by Will Ferrell, that being active and eating right isn't so "Ew!" Michelle Obama appears in 'Snackpocalypse'
