Barrack Obama and Michelle Obama dance to 'Thriller' at White House Halloween Party

US president Barrack Obama and first lady Michele Obama thrilled their guests with jokes and dance move as they host Washington-area children and their families at their last Halloween party in the White house on Monday as they dance to Micheal Jackson's Thriller. 

Obama told the assembled trick-or-treaters;

"It's great to see you guys. We hope you have a great time today. 

"You guys all look scary, or cool, or whatever you're trying to be..... awesome" You look awesome. And we hope you have a great time."

Obama made a joke to parents in the room that it was okay to ignore First Lady Michelle Obama's healthy eating tips for one day.

"We hope, parents, that on this day at least, you don't have to pay attention to Michelle and healthy eating."

"Candy for everybody," the first lady agreed.

"And in fact, the more candy, the later you eat the candy, the better," said the president. "Because I think that you being up all night with a sugar rush is exactly what your parents are looking for."

More than 4,000 people for trick-or-treating, mainly from 15 Washington-area elementary schools and military families were at the White House for the party. 

There were treats like Hershey Kisses, Halloween cookies, M&Ms, Fruit Bars, Kettle Corn, Bo and Sunny baseball cards and other assorted candies.
