Kim Jong-un limped his way on stage at his grandfather's memorial ceremony today. It's not clear what his injury is — maybe he's just being dramatic — but it's surprising that state TV captured his apparent weakness.
As The Guardian points out, when Kim Il-sung had a big inoperable tumor on the back of his neck, state media were only allowed to photograph and film him from certain angles.
In 2012, Kim Jong-un revealed himself to be a fitness expert, so perhaps he's just been hitting the gym too hard. State media has reported that he's been making military visits coast-to-coast for the last few weeks.
