Singer Jin Joon-Il released the theme song Running Man' for the first time.
On the 4th broadcast SBS 'Good Sunday - Running Man', Choi Soo-in, the second-ranked national athletics player, appeared in surprise.
On this day, Running Man' theme song composer Jeong Joon-Il appeared in Running Man'. Jeong Joon-Il, who is the first to appear in variety entertainment, greeted shyly. Jeong Joon-Il, who usually enjoyed Running Man', received a call from the party when he was in New York and accepted it immediately.
Jeong Joon-Il asked the members to call Kim Bum-soo's "I want to see" for part allocation. Jeong Joon-Il tried to keep the key down, but Yoo Jae-Suk and Ji Suk-jin laughed when they said they would call it a decisive wish.
Song Ji-hyo's song first, and the members as well as the crew could not bear the laughter, and Kim Jong-kook comforted him, saying, "I was trying to be funny, but I wanted to be funny." On Yoo Jae-Suk's turn, Jeong Joon-Il said he would play along with Yoo Jae-Suk's song, but Yoo Jae-Suk showed confidence, saying, "I'll follow you." However, the recording room was devastated by the song of Yoo Jae-Suk.
Ji Suk-jin stood up, saying, "I will show you my singer skills." In Ji Suk-jin's high-pitched song, Jeong Joon-Il laughed at the reversal, saying, "It is an old style to play with a beat." Finally, Kim Jong-kook raised a height and completely digested 'I want to see' and attracted attention.
Yoo Jae-Suk later commented on the modifiers written by the members, as they enter the lyrics to the theme song. In response, Jeong Joon-Il laughed, saying, "I received that by e-mail, but I did not want to do it." The theme song "Running Man" by Jeong Joon-Il was released.
On the other hand, the members raced "Why can't I eat" on the day. On the "Do not Scream" mission, the members struggled to laugh at each other for 15 minutes. In particular, Lee Kwang-soo dressed up as an avatar to laugh Kim Jong-kook, who only laughed once, but the end whistle sounded before he could show it.
