Kim Jong Kook on Brain Survival Show (video from KJK baidu)
The show has a similar format as the Taiwan Variety Show called "天才GoGoGo” hosted by Jacky Wu.
I've only watched part of the clip since my com can't seemed to finish loading the whole clip properly... But up to the point where I've watched, KJK got all of the questions correct! There's a question where all the rest of the guests got the answer wrong except for him. =D
