Why? Well, because the internet is a strange and wonderful place, that's why.
DJ Snake and Lil John's hit 'Turn Down For What' seems to be the favourite song of the internet, and using it as a soundtrack, Michelle Obama is trying to make turnips the favourite root vegetable of the internet...we think.
President Barack Obama impersonator Iman Crosson asked a question during a Q&A session on social media yesterday with the First Lady, and in a short Vine, he wanted to know "On average, how many calories do you burn every time you 'turn up'?!". Michelle Obama responded in style, by dancing with a turnip.
We're not sure either, but hey, why not?
