Singer Oh Jong Hyuk attracted the attention of the police officer trainees with his strong mentality that prevented him from falling down after getting shot with a teaser gun.

On KBS 2TV's pilot three episode long entertainment program, "Duty Clear," which aired on December 3, 2013, actors Lee Hoon, Ki Tae Young, rapper Defconn, singer Oh Jong Hyuk, and Hwang Kwang Hee of the male idol group, Nation, attended the central police school and received training. During the training lessons on this day, members came to the front of the class one by one and practiced getting shot by a teaser gun.

Oh Jong Hyuk, who earlier in the episode was made fun of by putting too much bb cream on his face, looked tense when the trainer said, "Think of happy thoughts" right before getting shot with the teaser gun. When the gun was shot, Oh Jong Hyuk fell onto the floor with a short shout, and then he rose back up. The other members clapped at him, awestruck by his strong side.

"Duty Clear" is a pilot program by KBS 2TV and a real variety show. Whether the show would be made into a regular entertainment show is not determined yet. The pilot show airs its final episode on December 6, 2013.
