劉在錫
On "Infinite Challenge", Park is "the second-in-command" (2인자), putting him below the host-in-chief Yoo Jae-suk, who is "the first-in-command" (1인자). This spawned a running gag in which he often jokes about overthrowing Yoo Jae-suk as leader and becoming "first-in-command" himself. He also called "Rice Insect" (벼멸구), a rival nickname for Yoo Jae-suk's famous "Grasshopper". He also claimed that his nickname should be "Big Star" (거성/巨星 "Geoseong"). He sometimes tries to make use of his seniority by lecturing the other members on various matters, such as becoming a star; however, they rarely take him seriously.
