Singer IU emulated Jang Woo Hyuk's 'buffering dance', unintentionally causing the audience members to explode in laughter. On the December 16th episode of KBS 2TV's 'Yoo Hee Yeol's Sketchbook', IU put on an adorable performance of "You & I". MC Yoo Hee Yeol asked the singer, "Have you ever discovered a hidden talent for dance?", and the singer responded, "Senior Jang Woo Hyuk made a recent comeback with his 'buffering dance'. I tried to do it at home, and I thought, if I just work hard, I think I too can dance." Yoo Hee Yeol then asked IU to show him some of her moves, and although she looked bashful, she went right into it. But the MC and the audience could not hold back their laughter as she awkwardly, yet adorably tried to emulate Jang Woo Hyuk. "I'm thinking about using this as my signature skill," to which MC Yoo Hee Yeol hilariously remarked, "I saw something really interesting today."
