Song Ji-hyo and Haha engaged in a war of nerves like spears and shields.
On August 29, SBS Running Man', a mystery 'Differential Race' was held to find the best Doll by Kim So Hee.
On this day, the members chose one limited edition handmade Doll in search of the Doll exhibition of Kim So Hee artist 'God of Handmade Doll'. Kim So Hee wrote a will that "by 8 pm today, the best will inherit both Doll's ownership and property to the person holding Doll."
First, the quality test was conducted to get a hint about the best Doll. It was Yoo Jae-Suk and Haha who got the hint with the 'I draw with memory' mission that draws the brand logo.
The second was the alma mater tour by writer Kim So Hee; the members followed the attack handed by the other party and decided to get off the bus through the game they recognized. Haha told Song Ji-hyo, "You have dated Kim Jong-kook," and Song Ji-hyo responded, "I have dated Kim Jong-kook."
Song Ji-hyo also counterattacked Haha, who had drawn love lines with himself in the past, saying, "You're still thinking about me." Haha also responded, "You were at Kim Jong-kook's house yesterday"; Song Ji-hyo, who heard this, hit back, "You thought of me yesterday." Embarrassed, Haha burst into laughter and was eventually defeated, so Song Ji-hyo urgently shouted "Go Eun-ah sorry" towards Haha's wife star.
The turnaround was unfolded. The best was Doll, who was actually cursed. Also, among the members, ghosts are hiding, and in order to save innocent humans, it was Race to find ghosts and cursed Dolls. In particular, Doll's stomach contains the names of the members and the identity of the ghosts, and when the ship is divided, the members are eliminated if the names of the members are not ghosts.
The members combined hints to find ghosts at Doll's house; however, the members failed their first attempt, and Kim Jong-kook, who was pointed out by the ghost, became the first dropout. In the second attempt, Yoo Jae-Suk was eliminated as a ghost's mark. The members speculated that the ghost was the weakest member when Kim Jong-kook Yoo Jae-Suk, who is considered to be a strong player in Running Man', was eliminated one after another. Haha went on to insist on cutting Doll's boat. Ji Suk-jin actively recommended Doll No. 3, and Doll No. 3 was a self-defeating figure with Ji Suk-jin's Name tag.
