Boy group B1A4's member Gongchan imitated the bug water strider, becoming an odd 'gag idol'.

On MBC Music "B1A4's One Great Day" airing on August 25, B1A4 having a gag survival game and going on a restaurant tour will be shown.

B1A4, after resting up at the sauna to relax their tense bodies, held a gag survival game. The game started with buckets as their props.

The members showed sides they had never shown before as they got involved in this game and Gongchan, as the cute youngest member, turned into a water strider using the four buckets, filling the sauna with shock and laughter. He was able to put on a gag show with a straight face on the whole time, even to the point the members called him a "complete idiot."
