Liver spots topped the agenda this weekend at a summit held by the four living former U.S. presidents. Meeting at Gerald Ford's Southern California ranch, the presidents discussed numerous liver-spot-related issues. Jimmy Carter reported having them on his arms. 'I have them all over my face,' Gerald Ford said. 'I also have them on my chest.' Secret Service agents were dispatched several times in Air Force Two to procure special, security-cleared vials of Pond's Medicated Cream for the talks. Also on the summit agenda: wheezing, moving from a seated to standing position, and arm fat. Secret Service costs for protecting the four living ex-presidents amounted to $27 billion for the three-day summit.
