Jihwaza

Jihwaza (작렬! 정신통일) was a South Korean game show airing on SBS from April 14 to September 15, 2007. Each week, two teams of celebrities led by Kim Yong-man and Hyun Young competed in various games requiring mental concentration, such as word games and another in which contestants had to contort their bodies into poses that would allow them to pass through Styrofoam walls with odd cut-outs.
