IU has become Wang Biho's next victim. On the episode of 'Gag Concert' that aired on the 20th, Wang Biho made IU burst out with laughter as he ridiculed some of her actions. As a starter, Wang Biho stated, "She's very good at playing the guitar. Did you play the guitar as your extracurricular activity?" "She's very good at singing, and maybe it's because she's young, but she just bursts out laughing while singing," stated Wang Biho, and then he imitated her 'Marshmallow' peformance. He continued to make fun of her for her laughters and stated, "I saw her talk on a tv show, and she talks by herself and laughs by herself." Wang Biho then concluded his 'Wang Biho treatment' with, "She kept laughing but in the end, her mascara started running. I thought ink was coming out of her eyes."
