Joe Biden was a guest on a recent “Teen Tournament” edition of “Jeopardy.” He was part of the category “Cars in America” asking the questions. “I’m Joe Biden,” he said. “As a car nut and the son of a man who managed an automobile dealership, I’m here to talk about the automobile’s role in our country’s past and present. So here’s ‘Cars in America.’” The first question was an opportunity to promote General Motors coming back from bankruptcy. “The Chevy Coach dates from around the time this became the world’s largest car company with cars like my favorite, the Corvette,” he said. “It held that position until 2008, then filed for bankruptcy, but now it’s back on top.”
