Outrun by Running Man

Infinite Challenge has been reported as the first "Real-Variety" show in Korean television history. The program is largely unscripted, and follows a similar format of challenge-based Reality Television programs, familiar to the audiences in the West, but the challenges are often silly, absurd, or impossible to achieve, so the program takes on the aspect of a satirical comedy variety show, rather than a more standard reality or contest program. In order to achieve its comedic purposes its 6 hosts and staff continuously proclaim, the elements of this show are the 3-Ds, Dirty, Dangerous, and Difficult.

The show where everything's made up and the points don't matter. Not a talk show, not a sitcom, not a game show, Whose Line Is It Anyway? is a completely unique concept to network television. Four talented actors perform completely unrehearsed skits and games in front of a studio audience. Host Drew Carey sets the scene, with contributions from the audience, but the actors rely completely on their quick wit and improvisational skills. It's genuinely improvised, so anything can happen - and often does.
