On tape: Baby puts fingers in president's mouth

President Obama got a Christmas Day surprise when a baby put his hand in the president's mouth.

Mr. Obama was posing for a photo with the baby's parents at the Marine Corps Base at Kaneohe Bay, Hawaii when it happened, during the president's holiday vacation.

Mr. Obama joked about it, saying he thought the baby just liked his "big nose," which caused the room to erupt in laughter.

According to the White House, the baby is 8 month old Cooper Wall Wagner, son of Capt. Greg Wagner, 25, and Meredith Wagner, 27.

Wagner has been in the Marines for 8 years.

The president and first lady Michelle Obama were visiting military families during their Christmas dinner of ham, mashed potatoes, veggies and apple pie.
