"1 Night 2 Days" Rain got angry at Jung Joon Yeon.

On the winter break special episode "Northern Kyung Ki Do Tour" of "KBS 2TV Happy Sunday - 1 Night 2 Days" which aired on January 19, 2014, the 1 Night 2 Days members Kim Joo Hyuk, Kim Joon Ho, Cha Tae Hyun, Defconn, Kim Jong Min, and Jung Joon Young greeted the world star singer Rain as the third morning angel of the show. While they greeted Rain as the morning angel, they were not welcoming him, since the previous two morning angels have come from the girl groups.

1 Night 2 Days member Jung Joon Young went further to say to Rain, "Pack your belongings and leave!" and Rain said, angrily, "It is my first time a younger singer is yelling at me."

However, Jung Joon Young kept attacking Rain. When Rain was playing the water bomb game with the 1 Night 2 Days members, Jung Joon Young attacked Rain again. In this game, Rain was not supposed to say the words, "I do not know." Jung Joon Young made him get water bombed by asking him a question that he did not know the answer to. Rain got enraged again and said, "Anybody else can attack me but you!" and yelled at Jung Joon Young. And Jung Joon Young laughed it off.
