I think most of us have heard about the famous Teuk Academy. If you haven't, Teuk Academy is a corner on the popular SBS variety show Strong Heart. It features three Super Junior members: Leeteuk, Shindong, and Eunhyuk.� Each week they find new ways to� entertain the crowd while also helping the celebrities on the show show off different sides of their personalities and hidden talents. On this week's Teuk Academy, the notable celebrities were Changmin (2AM), Key (Shinee), and Se7en. Members of the Teuk Academy created a talent competition like atmosphere to get these stars to show their hidden talents. The first called up was Changmin. They showed the audience� his profile with the picture cut out and when overlapped with his face it emulated his profile as seen on the internet.� When asked to show his talent, Changmin chose to surprise the audience with his tumbling skills.� Afterward, he did a short rendition of one of Park JinYoung's songs. Unfortunately, Eunhyuk disqualified him because he was sick of singers doing impressions of their bosses.� This brought laughter to the audience. Key was the next one up.� When asked what his special talent was, he replied, "I'm good at dancing the girl group choreographies, but because JoKwon (2AM) does it so often he is known for it more." He also added, "JoKwon is good at bringing laughs with his dances, but he isn't dancing well." He tried to prove that he is the king of girl group dances by dancing to Miss A's Bad Girl Good Girl. This pleased the crowd and he passed Eunhyuk's standards. Se7en participated last. When Shindong remarked that the profile said Se7en's height was 181cm, Se7en replied, "That is with my hidden insoles." When asked what his real height was he said, "Roughly 179cm." Then he brought laughter to the crowd by saying that he had no special talents.� However, the Teuk Academy got him to do a few dances that impressed everyone. Watch the video below:
