If it's furry like Dad's, it must mean he's next in line.

No one has so far been able to prove that Kim Jong-il's son, Kim Jong-un, is being groomed to take over North Korea... until now. Analysts and defectors have concluded that Little Kim's new fur hat proves he's taking power.
Kim Jong-Un's New Hat Is Proof He's Taking Over North KoreaThe stylish (and functional!) headgear, which was normally reserved for Kim Jong-il's righteous head, has recently been spotted on Kim Jong-un. The picture here shows the Kims in what looks to be pretty cold weather, with Little Kim's head uncovered and presumably quite chilly. But the recent picture above shows a gripping new development. South Korean newspaper Chosun Ilbo spoke to a North Korean defector about it:
A former senior North Korean official identified as Choi, who has defected to South Korea, said, "The hat was customized by a foreign master craftsman using top-quality otter fur. It's an unwritten rule that nobody else can wear such a hat, so if Kim Jong-un is also wearing one, it means he has now reached almost the same status as his father."
