Barack-Michelle danced to Michael Jackson song on Halloween

US President Barack Obama and wife Michelle danced to Michael Jackson's 'Thriller' at White House's annual Halloween party on Monday. "We don’t know how it's (the dance) going to go, but... we should try it anyway," Obama said. The decor of White House grounds was inspired by classic tales, including 'Alice in Wonderland' and 'The Wizard of Oz', among others.
