That mistake will cost you...dictatorship!

Apparently, attempting to go to Disneyland is something that not only 20+-year-old North Koreans strive for, but it can also cost them a shot at dictatorship.

Kim Jong Il is known to have three sons -- one from his second wife and two from his third. North Korean experts say Kim's 25-year-old son Kim Jong Chul is most likely to become the North's next leader.

His eldest son, Kim Jong Nam, is said to have fallen out of favor after embarrassing his father in 2001 when he was caught trying to enter Japan on a fake passport, saying he wanted to visit Tokyo Disneyland.

Ouch...tough penalty!
