Choi Jin-sil
Yoo's television debut was on the KBS Comedian Festival (for college students) in 1991, where he performed a parody of a commercial with Choi Seung-gyung. His dancing to a cover of the song "Step by Step" by New Kids on the Block was another early memorable moment. In 2002, after nine years as a relatively unknown comedian, thanks to a recommendation by Choi Jin-sil, he hosted the program "Live and Enjoy Together". He then rose to prominence when he co-hosted a program called "The Crash of MCs" with Kang Ho-dong, Lee Hwi-jae, and Kim Han-seok.
