On the last episode of 'Idol School Trip' that aired on December 9, Jung Hyung Don received a chance to speak with the founder of YG Entertainment over the phone. The comedian said, "Principal, after finishing up all the scheduled events, we're doing an exit ceremony right now."

Yang Hyun Suk replied, "iKON's album is coming out soon, I hope it does well." Jung Hyung Don, not satisfied with the response, raised his voice, "Instead of saying stuff like that, tell them they did a good job and that you love them." Yang Hyun Suk responded, "I don't usually speak with warm words."
