A visit from friend and fellow former president, Bill Clinton, inspired him to wear a pair emblazoned with Clinton's face. He wore Houston Texans' socks when meeting with the head coach. At the funeral for his wife, Barbara Bush, former President George H.W. Bush wore socks featuring books as a tribute to her work promoting literacy. Bush, who was a naval aviator in World War II, will be buried this week wearing socks featuring jets flying in formation — a tribute, his spokesman says, to the former president's lifetime of service.
