In late 1991, he was selected as an
SBS special employment comedian in tandem with the channel's launch. His catchphrase in the
I Like to Laugh corner "Rail Man", "안녕하시렵니까", gave him immediate attention. He also became a model and was regarded as a handsome comedian along with
Lee Hwi-jae and
Park Soo-hong. He continued his popularity, appearing in programs like the SBS variety show
Happy Our Saturday and the
MBC sitcom
Guys and Girls, until he took an 11-month hiatus in 1999 due to being charged with smoking marijuana. He returned to TV in 2000 through the
Sunday Night corner "Love House". Subsequently, he enjoyed his golden age with shows like
Happy Together,
Exclamation Mark, and
Hey Hey Hey. After the mid-2000s, his specialty of acting and skits hosting alone did not fit with the zeitgeist of "real variety" and group hosting, and shows that he starred in like
Quiz Prince,
Oppa Band,
Champagne, and
Night Star were cancelled due to low ratings. Afterwards, his quick-witted hosting in audition programs like 2011's ''
Kim Yuna's Kiss & Cry'' and 2012's
Immortal Songs: Singing the Legend gained him popularity, and by becoming the main
MC of programs like
Hello Counselor and
Strong Heart he experienced a second golden age, winning the grand prize in the 2012
KBS Entertainment Awards. He is recognized on cable channels for his characteristic sex comedy. == Filmography ==
