About Park Myung-soo

The "second-in-command"
On Infinite Challenge, Park plays the "second-in-command," ranked below host Yoo Jae-suk. That set up a running gag in which he plots to overthrow Yoo and take the top spot himself. He is famous for his "scolding" comedy, angrily telling off his co-stars over trivial things, and for flubbing words mid-rant, which only makes the others take him less seriously. His squabbles with Jeong Jun-ha grew into a recurring segment, "Ha & Soo." In 2011 the pair won Best Couple at the MBC Entertainment Awards, the first male-male duo ever to take the title.
A nickname for everything
Fans know him by many names, including "Big Star," "Chicken CEO," from the Kyochon chicken shop he once ran, and "Old Devil," opposite Noh Hong-chul's "Young Devil."
Radio star and Daesang winner
He hosted the Date at 2 o'clock radio show and won Best Radio DJ at the KBS Entertainment Awards in 2016 and 2021 for KBS Cool FM's Park Myung-soo's Radio Show.
