From Mr. Crab:  Whilst on assignment today, I met former President Bill Clinton at a book signing in downtown London today. About 500 people attended the event, mostly star-struck Brits but also a few American expats and curious tourists who happened upon the event.  Clinton was there to pitch his new book, "Giving."

Random trivia: I have shaken the hand of the last four U.S. Presidents: Ronald Reagan, George Bush Sr., Bill Clinton and George W. Bush.
