During UNB's debut stage on 'Yoo Hee Yeol's Sketchbook' this week, an interview took place for the viewers and audience to get to know more about the group. While doing so, Yoo Hee Yeol asked Marco, "Did you take a comedian test/exam before?"

Marco answered, "Actually when I was in high school, I went to KBS' gagman/comedian open audition." When asked if he did well or not, he replied, "I utterly failed," that made the entire audience burst out into laughter. 

Meanwhile, UNB made their debut today with the release of 'Boyhood' and its two title tracks "Sense" and "Only One".
