On the May 25 broadcast of 'Happy Together 3'., Kim Yong Man, Ji Seok Jin, and Kim Soo Yong joined as the guests. During the show, the three guests were given the mission to invite Jo In Sung, Gong Yoo, and Song Joong Ki, who are the top 3 stars that the viewers want to see as guests.
Ji Seok Jin first tried contacting Song Joong Ki but failed. Yoo Jae Suk then called Lee Kwang Soo, who's close with Song Joong Ki and said, "Kwang Soo yah, Joong Ki's not answering the phone right now. Can you call him and ask why he's not answering?"
Kim Yong Man brought laughter as he also asked Lee Kwang Soo, "Can you give me Jo In Sung's number?''
