Yoo Jae Suk Treads on Dangerous Ground and Makes Fun of Kim Jong Kook's Age on "Running Man"

This week’s “Running Man” featured the same quests as last week- actors Ji Sung, Joo Ji Hoon, and Baek Sung Hyun, pool player Cha Yoo Ram, TV personalities Sam Ochiri and Fabian, comedian Heo Kyung Hwan, and A Pink‘s Bomi and Son Naeun. The theme of this episode was “One Day Tour Race,” set in the city of Yeong Cheon.

While all walking together, Yoo Jae Suk, who was jealous of Kim Jong Kook being partners with Son Naeun, began making fun of the athletic cast member. He commented loudly so everyone could hear, ” Jong Kook is turning forty years old next year.” He then began chanting at Kim Jong Kook, “Kim Forty, Kim Forty.” Kim Jong Kook growled at Yoo Jae Suk, but the “nation’s MC” couldn’t stop making fun of the ruffled “Spartakooks.”

Kim Jong Kook was born in 1977, making him 37 this year, but in the way Koreans calculate age, Kim Jong Kook could be either 38 or 39 this year, making him forty next.
