Four handsome fellas will be making an appearance on the January 8th broadcast of SBS's 'Running Man'. Their dashing appearance has already earned them the title, 'F4' as depicted on the popular Korean drama, 'Boys over Flowers'.  The four guests will be: Ji Jin Hee, Lee Chun Hee, Kim Sung Soo, and Joo Sang Wook. The recording took place at Yeosu, Jeonnam where the 'F4' carried out missions in two teams; Ji Jin Hee teamed up with Joo Sang Wook while Lee Chun Hee was partnered with Kim Sung Soo. Singer IU joined in on the fun on the second day, adding a new flavor to the show. It was reported that on the first day, people swarmed to the filming area when they recognized the identity of the 'F4'.  This caused the traffic to slow down as the locals swarmed in by the hundreds.  Photos of the recording were spread like wildfire on online blogs and community sites. Ji Jin Hee and Lee Chun Hee, who are currently enrolled in the new drama 'Take care of us, Captain', made a comment during the recording of the show. "In light of the new year, we are trying to show our fun sides through 'Running Man'.  We are running hard so please anticipate us and watch our drama." Meanwhile actor Joo Sang Wook, who is busy acting in the OCN drama 'Special Crimes Force Ten', expressed, "'Running Man' was a new experience. I can't remember how the one night and two days passed by because it was all so fun.  It was such a fun time that I even wanted to be a permanent member on the show." Lastly, Kim Sung Soo commented, "I frequently enjoy and watch 'Running Man'.  I had a great time recording the show. As hard as I ran, I think the broadcast will be a lot of fun to watch.  First weekend of the new year with 'Running Man'~!" Don't miss the show this Sunday and check out the preview below!
