On last week's episode of SBS's 'Running Man', viewers saw Ji Jin Hee, Joo Sang Wook, Lee Chun Hee, and Kim Sung Soo appear as special guests on the show. This handsome crew had the seven hosts begging for mercy, as they tore off each and every one of their name tags in practically no time at all.

Fans can expect another great episode this week, as the terrifying foursome will be joined by singer IU!

Several shots of IU and actor Kim Sung Soo were revealed online, hinting at a duo intent on achieving victory. The two stars had teamed up, travelling to and from several locations by car.

Netizens commented, "Kim Sung Soo, we are counting on you to represent us (uncle fans) and protect IU with your life", "IU must have felt safe with Kim Sung Soo", and "Can't wait for the episode!"
