Guess what SG Wannabe's leader, Kim Yong Joon did during his high school years? He was a reenactor! Who would have known? On the most recent episode of MBC's "We Got Married", Kim Yong Joon was busy practicing acting to make a cameo appearance on the sitcom starring his girlfriend, Hwang Jung Eum, "Highkick Through the Roof". Child actress, Suh Shin Ae and Jin Ji Hee assisted his acting as well. Hwang Jung Eum said, "I told the director that Kim Yong Joon is a good actor and asked him to appear on the show, and he agreed to it." Kim Yong Joon, on the other hand, could not hide his embarrasment as he said, "I never acted before." To this comment, Hwang Jung Eum blurted out, "Why? Weren't you a reenactor during high school?" and the truth was out. The screen switched to a clip of the 2002 reenactment show called, "Time Machine", where you could see the young Kim Yong Joon's fresh acting! Kim Yong Joon was surprised by the sudden flashback clip and complained, "How did you guys find this clip?" His embarrassment made everyone in the studio burst out in laughter.
