Singer Kim Jong Kook got down on his knees for nation's MC Kang Ho Dong once. On the upcoming episode of Strong Heart, the show decided to have a special called "Men's Scent." This means the guests are most likely going to be mostly composed of men. On this episode, Kim Jong Kook admitted he's got down on his knees for Kang Ho Dong in the past. What would make this full of price man do such a thing? Kim Jong Kook said, "Kang Ho Dong and I need to resolve something. Kang Ho Dong stopped taking my calls after I joined Family Outing with Yoo Jae Suk." Kang Ho Dong tried to deny this accusation and that's when Kim Jong Kook blurted out, "Didn't I get down on my knees for you (Ho Dong) at Jung Hyung Don's wedding?" Kang Ho Dong responded, "So who is on speed dial #1 on Kim Jong Kook's phone?" Kim Jong Kook answered, "Yoo Jae Suk." We all know Kang Ho Dong and Yoo Jae Suk are great friends but you have to admit, Kang Ho Dong definitely is jealous of Yoo Jae Suk more than Yoo Jae Suk is of Kang Ho Dong. This episode airs on the 23rd.
