Yoo Jae-suk and Jeong Jun-ha of MBC reality show “Infinite Challenge” teased fellow cast mate Park Myung-su on Thursday, making fun of his “sloppy” DJ skills that he showed in a live radio show.

Yoo and Jeong singled out Park because he showed the highest confidence when the entertainers were challenged to host a live radio show.

“I am disappointed to hear he was all thumbs in this morning’s radio show,” Yoo said in a phone call with Park while the show aired at 91.9MHz, driving the audience into laughter.

Jeong also criticized Park’s hosting skills. He said, “Park’s radio show gave me so much confidence… I was so relieved to see that a man with such a long career as a radio DJ could mess up the show so badly.”

Each of the six Infinite Challenge emcees were given the mission to host a show at MBC’s radio station. After Park’s 7 a.m. radio show “Good Morning FM Park Myeong-su” came Jeong’s show at noon and Noh Hong-chul’s at 2 p.m.

Jeong Hyung-don’s “Jeong Hyung-don’s Music Camp” and Yoo’s “Yoo Jae-suk and the Dream Radio” aired at 6 p.m. and 10 p.m., respectively. Haha closed out the event with his midnight radio show “Pureun Night Haha.”
