On 2 November night MBC variety show 'Golden Fishery - Radio Star' as invited guest, SS501 Heo Young Saeng and Kim Hyung Joon, due to their lower popularity resulted that they have to do a self introduction, making the audience laugh.

Heo Young Saeng was selected by SS501 as the No. 1 member that most needed self introduction. Due to that, DJ Kim Guk Jin showed a puzzle faced and said: "So you are actually the lead singer ah...." At this time, Heo Young Saeng's face became darker and answered: "It is me ah." causing the studio to fill with laughters.

Following by that, DJ Yoon Jong Sin said: "This artist when was alone in the management company, I felt that I will pass my name card to him." The answer was revealed as Kim Hyung Joon, making Kim Hyung Joon very shocked.

DJ Yoon Jong Sin explained: "Because Kim Hyung Joon's name is too similar to leader Kim Hyun Joong's who has high popularity in the entertainment circle, in addition, he does not have any special part to be differentiated by the general public." Once completed, he introduced Kim Hyung Joon once again, causing another round of laughters.
