Michelle Obama might be an outspoken advocate for healthy eating and the fight against obesity but even she is all for the idea of letting your hair down at Halloween. 

At least that's what her husband said to a group of children and students who joined the presidential family at the White House to celebrate Halloween this year.

With it being their final Halloween in the White House, the Obamas had a special treat for those who attended. 

“We’ve been working on a little dance. We don’t know how it’s going to go, but we think we should all just try it anyway.”  POTUS said, before he and his wife got down to the tune of the Michael Jackson, Thriller.
