Aired on Jan. 8, Sunday, the said episode also featured a challenge where Ji Hyo's cast members were asked a question while their hand rested on a toy lie detector device. With the threat of getting a quick electric zap from the said toy if it sensed that a member gave an incorrect answer, the actress' cast members nervously participated in the game while Ji Hyo acted as the emcee.

Kwang Soo was the first "Running Man" cast member to undergo the lie detector game where he confidently stated that he is at par with Joong Ki's popularity. The "Sound of your Heart" actor passed the said test, but eventually failed the game when he shared that he was better than his celebrity friend Jo In Sung.

As for Jong Kook, the singer's lie detector test questioned whether he still harbors romantic feelings for "Princess Hours" actress Eun Hye, whom he was linked with during their days as members of the variety show "X-Man." Despite stating that he no longer likes the said actress, the lie detector machine deemed his answer incorrect.

In other news, both Jong Kook and Ji Hyo were at the center of a "Running Man" casting controversy in December that resulted in the SBS cast and crew members' decision to end the variety program. Following the announcement of the show's cancellation, producing director (PD) Jung Chul Min told local reporters that the said controversy arose from miscommunication issues, My Daily quoted the PD as saying.

Meanwhile, members of the said SBS variety show are set to continue with the planned Taiwan fan meeting to be held on Feb. 10, Friday. A source told Yonhap News that the said fan event will proceed despite the show's impending end, however, Yoo Jae Suk will be unable to join due to a conflict in schedule.
