Among Gag Concert legends like Shim Hyun-seop, many haven't stood out in variety shows

There are many people who haven't really stood out in variety shows
Park Joon-hyung, Park Seong-ho, Jung Jong-cheol, Oh Ji-heon, Hwang Hyun-hee, Choi Hyo-jong, Jung Man-ho, etc.
Even someone like Kim Byung-man is completely boring when it comes to witty banter, and the same goes for Kim Jun-ho or Kim Dae-hee.
