Kim Jong Un and his cronies in Pyongyang have terrible senses of humor. That makes them really easy to troll. Like remedial-photoshop-easy to troll.
And with such ease comes such glory as this video, which, according to the government in Pyongyang, "seriously compromises Kim's dignity and authority."
There's not much else to say about it, except that it was made by someone from Suzhou, China who had studied at a South Korean university. The track is by a Chinese pop duo, the "Chopstick Brothers."
