Rapper DinDin jokes he's got the dirt on Kyuhyun on 'Radio Star'

Rapper DinDin was one talkative guest on the August 27 installment of MBC's 'Radio Star,' even revealing at one point that he had some dirt on MC Kyuhyun?

He said, "I heard Kyuhyun went to a gym with my chief, Deux's Lee Hyun Do," which Kyuhyun confirmed he had in the past.  DinDin continued, "I heard a lot of things from him like with whom Kyuhyun drank, whom he met, and more, so I have a nuclear bomb," making everybody on the set laugh.

He continued, "So when you go to the army in my place, I'll keep my mouth shut and do nothing for two years," causing even more laughter.  DinDin said, "If I blow this up... You're going to have to go to the army, anyway."

Kyuhyun gradually looked more and more uneasy to everyone's amusement, saying, "But Lee Hyun Do doesn't know me very well."  DinDin explained that he was close, however, to the other members and heard some things.

Kyuhyun once again said that is why he kept quiet about things even among his members. Another guest, Yoo Jung Hyun, joked, "If you blackmail like this to become an MC, then who will maintain social justice?"
