Today, you might think the G in G. Gordon Liddy stands for gold, considering many people probably best know Liddy as that mustachioed guy who hawks gold investments in advertisements on Fox News. "Listen to that," Liddy says in one commercial as he jingles handfuls of coins. "That's the sound of security. That's the sound ... of gold!" But for years, he was better known as the law-breaking leader of the White House Plumbers, the group ultimately responsible for the Watergate break-in in 1972 that brought down President Richard Nixon. Liddy spent about four and a half years in jail for conspiracy and contempt of court. But somehow, Liddy has remade himself, hosting his own radio show and repairing his image enough for companies to hire him as their spokesman.
