Navy Corpsman, Christopher Duke, who is on leave from Afghanistan, is overcome with emotion as he hugs his son, Brayden Duke, 3, after surprising him and his sister, Brilee Duke, 1, on Sunday, June 1, 2014, in the Delbridge Museum of Natural History at the Great Plains Zoo in Sioux Falls. Duke hadn't seen his kids since December 26, his wife, Sondra Duke, said. "I'd give anything for these two," Duke said about his kids, "I love them more than anything." Duke was dressed as Batman as a birthday surprise for his son's upcoming birthday.
