Pint-sized goblins, pirates, ninjas, and princesses took over 1600 Pennsylvania Avenue for Halloween tonight. President Obama, the First Lady and First Grandmother Marian Robinson handed out tasty treats to kids in what can only be described as organized chaos on the South Lawn of the White House. "Look at you!" the president, dressed in an orange shirt and black sweater, exclaimed as he exited the residence and was greeted by throngs of eager trick-or-treaters. Happy Halloween! Children, who had lined up with their families, spoke briefly to the Obamas as they were ushered through, their parents trying desperately to snap pictures. "You look beautiful," Mrs. Obama, in bright orange pants and an orange and black sweater, told one princess. A few confused little ones are wandered off. At one point, the First Lady was seen motioning to a tiny cowgirl who had gone astray, distracted by the decorations. There were power rangers, witches and astronauts. Several Spiderman and Harry Potters. One family was dressed up as a s'more - the baby was the marshmallow in the middle. The president spoke to them all, patting several on the head and even saluting a few of those dressed up as soldiers. "Terrific, a gold medalist," he told one Olympian. "Hey there, cowboy," he was overhead saying to another little boy. The White House was transformed into a spooktacular fright fest, complete with giant spider webs, ghosts and a larger than life Frankenstein. More than 5,000 people visited the White House for Halloween this year and the decorations did not disappoint. The South Portico was draped with giant spider webs and the staircase was adorned with orange and black garland. A massive spider loomed over the door and large black cats made of balloons floated nearby. Hay bales and jack-o-lanterns dotted the driveway and a group of ghosts were gathered on the edge of the South Lawn. Roaming throughout the festivities were Frankenstein and his bride, both on stilts, and Glinda the Good Witch, who floated across the grass in a giant plastic bubble. The Obamas doled out treats, including White House M&Ms, jelly beans, cookies and dried fruit (which may be more trick than treat). The First Dogs also got in on the fun. A giant topiary of "Sunny" made of ribbon was dressed as a sunflower and a huge "Bo" made of pipecleaners was wearing a pirate costume.
