This show is the first real variety show in Korea. The seven members of the team try new challenges for each episode. For example, they held an end of year concert to raise money for unfortunate neighbors, made a drama, met and played games with world famous stars like Thierry Henry and Paris Hilton. These were all produced by Kim Tae-ho, the producer of Infinite Challenge. He wants to keep the program new and exciting so he has recently tried to add a new member of the team.
