I love some of the crazy claims he made during his lifetime.
North Korean schools teach children that Jong-il's birth was "supernatural." He was born in a log cabin inside a secret base on the sacred Mt. Paekdu, the story goes, and his arrival was accompanied by the apparition of a new star. The seasons then spontaneously changed from winter to spring, and a double-rainbow appeared, followed by a talking iceberg. (Western accounts say he was born in a guerrilla camp in Russia.)
State textbooks claim Jong-il does not produce urine or feces.
Jong-il long claimed to be the world's greatest golfer. In 1994, Pyongyang media reported that he shot 38 under par on a regulation 18-hole golf course, including 5 holes in one.
