This is just some American person impersonating what a North Korean would sound like. If you Americans knew that Koreans don't actually sound like that, and that some of the citizens speak better english than you, you'd be fucked in the ass by them. Asians tend to be smarter, better reflexes, understandment levels higher, and able to control what they want (willpower).
This video is just some racist making fun of themselves. Koreans are smarter than him, no matter how you look at it.
