Thai King Bhumibol Adulyadej waves to a crowd of well-wishers as he leaves the Siriraj Hospital in Bangkok on December 5, 2009.  Thailand's revered king called on the politically divided nation to unite during a brief public excursion from hospital to mark his 82nd birthday. King Bhumibol Adulyadej, the world's longest reigning monarch, who is regarded as a demi-god by many Thais, made a rare address at Bangkok's royal palace where dignitaries were gathered for his annual birthday ceremony.
