Actor Jang Hyuk failed to catch the voice of close singer Kim Jong-kook.
On sbs Running Man' broadcast on November 9, members were shown calling other members' families or acquaintances to pretend to be mobile phone owners.
The crew announced that if they quickly identified the caller, they would handle the mission success.
Comedian Yang Se-chan started talking to Kim Jong-kook, Chuck Kim Jong-kook, and his close friend Jang Hyuk.
"Hey you're not calling (the car)Taehyun again these days," asked Jang Hyuk, noticing that he was Yang Se-chan. Yang Se-chan posed as Kim Jong-kook, saying: "I'm going to die; why do you keep drinking and calling Taehyun?" So Jang Hyuk started to unpack the story bag saying, "He is nowadays."
Kim Jong-kook later said, "You've been talking to Sechan now," and Yoo Jae-Suk said, "Hyo-ah, how do you not know the voice of the end?"
Jang Hyuk laughed, saying, "We're not very close." Kim Jong-kook resented, "You've ruined it, now." Jang Hyuk suspected, "You're not now?" and Kim Jong-kook added a laugh by shouting, "I'm right, it's me."
