Singer Yoon Do Hyun and MC Kim Jae Dong will be bringing their charm and wit to an upcoming episode of SBS's 'Running Man'. On January 11th, 'Running Man' producer Cho Hyo Jin informed Star News that "On the 10th, Yoon Do Hyun and Kim Jae Dong completed shooting at the Busan Cruise." The PD continued, "It is a 'Sherlock Holmes' special, and there was good chemistry between the guests and the cast members. Kim Jae Dong is always intense when it comes to a battle of wits, and so he was a great addition to the show, while Yoon Do Hyun is sweet and a bit goofy. He's even better suited for entertainment and variety shows that we expected." This 'Sherlock Holmes' Special will air on the 29th, so mark your calendars 'Running Man' fans!
