HONG KONG–At first glance, David Hogue seems like an unlikely reality TV star. He isn’t an acid-tongued Brit or a member of a once famous hair band. He has little penchant for drunken fist-fights, or marathon “smooshfests.” And, of course, his name isn’t “Snooki.” Instead, he’s a bookish, 26-year-old Princeton graduate completing a master’s degree in ancient Chinese classics at Nanjing University. Yet three years ago, as he was walking between classes, a producer from the Jiangsu Variety Channel, a television station in one of China’s eastern provinces, invited him to compete on a game show.
