When you're a kid, there's nothing better than going out to trick or treat with your parents – but these children were very lucky because they went trick or treating on the front garden of the White House. 

Barack and Michelle Obama welcomed the children of military families to come to the White House for a festive afternoon, but we don't think Barack was expecting such genius costumes. 

Obama absolutely cracked up when the world's smallest Pope landed on his doorstep, along with his clever dad. #ParentGoals.

He loved the costume so much he brought Michelle over to see it too.

The Obamas also welcomed a flurry of witches and princesses alike on the day, as well as an American Cub player.
