Every little girl dreams of having a pony, but young CAROLINE KENNEDY actually had one. A gift from LYNDON B. JOHNSON, the pet pony roamed around the JFK White House gardens and made for great photos. So great that Neil Diamond has said that one of those photos inspired his hit song "Sweet Caroline." I've never discussed it with anybody before — intentionally," the singer-songwriter told the Associated Press. "I thought maybe I would tell it to Caroline when I met her someday."
