B1A4's member Gongchan revealed an ugly funny picture of himself.

On August 13, B1A4 came out on MBC Everyone "Weekly Idol" as guests. On this day, the members were given the mission to dance to the medley of their hit songs.

If B1A4 fulfills the mission without getting any moves wrong, then they get the chance to hit the MCs with a toy hammer and if they fail, ugly pictures of the members would be released.

The members did well for the most part but one little mistake led to their failure. At this, Gongchan's funny picture where he was making a double chin at the camera was shown, filling the studio with laughter.
