Boy group, MBLAQ made a guest appearance on today's broadcast of SBS' 'Running Man'.  Although there was a lot of hype over Park Ji Sung's attendance on the show, he did not physically participate in the program.

On today's broadcast, the Running Man members were directed to find the hidden running men scattered around their designated areas. During the process, MBLAQ made a brief appearance and was missioned to attack Song Ji Hyo with water guns. Of course, the Running Man members were also equipped with lethal water guns of their own, to scare away any incoming enemies.

The first victim was none other than member, G.O, who was shot down by the one and only Korean terminator, Kim Jong Kook. Lee Joon became the second member to get eliminated. Hilariously, Lee Joon positioned himself on top of a roof, but was quickly spotted by the running man team.

Yoo Jae Suk, Ha Ha, and Lee Kwang Soo decided to head for the roof top and shoot him down themselves. Lee Joon, who was caught off guard screamed, "AHHHH!" when Yoo Jae Suk appeared before him. The running man members became startled by his scream as well, and tried to calm him down.
