'Running Man' Episode 570: Kim Jong Kook's Candid Comment to Song Ji Hyo Sparks Chaos

The "Running Man" members never fail to tease each other, especially in their response to some of the candid things that happened to their co-mainstays.

After saying this, Yoo Jae Suk picked up on it immediately and questioned the singer's motive.

Naturally, the response to the comment created mass chaos on the program, as Haha and Yang Se Chan banded together and sang a famous line from TVXQ's "Hug."

"Just for one day, I would like to be the bed in your room."

The entire "Running Man" crew started to tease and poke fun at Kim Jong Kook as he tried to explain his comment.

"I meant your own personal bed. Run and jump as if you're about to lay in your own bed," the singer explained.

However, no one listened and the show's favorite Sparta chose a victim to take his anger out on and at that time, it was Yoo Jae Suk.

As the segment continued, Song Ji Hyo geared up to complete her task, Haha on the other hand, couldn't help and made fun of the situation by sharing another bed-related comment

"To make Song Ji Hyo feel more at ease, can you do what you normally do for her and offer your arm as a pillow?"

Following this exchange of teases, Song Ji Hyo finally gave her best and completed her high jump, but failed with her attempt. As she brought laughter to her members with her comedic stunt, Yoo Jae Suk and Kim Jong Kook assisted her in standing up.
