Kim Jong Un loves basketball. There's even a picture of him wearing a Dennis Rodman jersey in his youth (courtesy of Gawker). Luckily, Dennis Rodman visited North Korea with members of the Harlem Globe Trotters who competed against players from North Korea. Rodman watched the basketball game with a very happy Kim Jong Un and told him that he has a "friend for life."
