The episode started off with the cast of 'Knowing Brothers' praising Yoo Byung Jae and his recent rise in popularity, even commenting on his popular phone case. Kang Ho Dong said, "I've noticed that many famous stars have been using Yoo Byung Jae's phone case." The comedian added, "I did it by a chance - even AOA's Seolhyun and A Pink's Eunji have the case. It actually did very well."

Hearing this, Heechul asked, "Is it selling better than WINNER's goods?" Kang Seung Yoon answered that it was. Yoo Byung Jae, who felt very proud at the moment, finished by saying, "It sold the most in the history of YG's phone cases. It beat Big Bang as well."
