On the episode of Gag Concert that aired on the 20th, CNBLUE was in the crowd of the audience. Usually, celebrities come on so that they get made fun of by Wang Biho (Yoon Hyung Bin) at the end although he wasn't around tonight with Song Joon Geun taking his place. This time, there was even a bigger surprise for particularly one member, Jung Yonghwa. Song Joon Geun said, "I heard Yonghwa was coming today so I got (SNSD's) Seohyun to come too." Since the two idols are "married" on We Got Married, their relationship is a hot topic amongst the public. People were excited to see Seohyun come out but it turns out it was comedian Kim Jiho in a SNSD Oh! outfit. He looked quite scary but hilarious at the same time. He went on to play out a scene from the show and made Yonghwa crack up for quite a while as he tried to run away from the horror who wanted skinship. Check out the hilarious scene! http://www.youtube.com/watch?v=M89LbZ1cT60
