On the December 8 airing of KBS CoolFM 'Jung Jae Hyung and Moon Hee Jun's Fun Life' radio show, Tony An and Kangta made a special guest appearance.
During the show, Kangta mentioned, "Moon Hee Jun is considered 'Honey Jam (very funny)' and I am called 'No Jam (not funny)," to which Moon Hee Jun responded, "Kangta is really funny when it's just us. I scolded Kyuhyun on 'Radio Star' when I heard that he came up with Kangta's nickname, 'Asia's No Jam'."
When Kangta heard this, he said, "No, it was Yoon Jong Shin who made my nickname," making Moon Hee Jun flustered. He said, "I scolded the wrong person."
