That's one hungry, hungry hippo! Actor Harrison Ford, fiancée Calista Flockhart and her son Liam, 8, paid a visit to the Smithsonian National Zoo
in Washington, D.C., on Wednesday and had the chance to get up close and personal with Happy, the 22nd Nile hippopotamus to be born at the facility. Though Happy is said to be friendly, Ford, 66, was the only one brave enough to feed the 5,000-lb. mammal! Afterward, the family toured the zoo's famed giant panda exhibit, where 3-year-old Tai Shan, his mother, Mei Xiang, and his father, Tian Tian, reside; peeked in on some lions and tigers; and saw the zoo's newest primate, baby gorilla Kibibi, a female born in January.
