Osen - Naver: 'Running Man' PD, "Jo In Sung and Song Joong Ki take the top spot on our list of most wanted celebrities to guest"
1. [+5,087, -73] I remember when Song Joong Ki was a Running Man member
2. [+4,382, -121] Song Joong Ki used to be a member but it's now a challenge to invite him to guest. He got super popular
3. [+4,089, -149] Yoon Eun Hye was the most wanted celebrity guest... but she ran away to China
4. [+3,240, -619] How awkward it would be for Jo In Sung and Song Ji Hyo?
5. [+425, -47] I want Yoo Seung Ho to guest. Upvote if you agree, downvote if you don't
6. [+347, -42] Running Man's popularity dropped when Song Joong Ki left
7. [+300, -20] Song Ji Hyo and Jo In Sung are close though. It would be fun to see Kwang Soo and Jo In Sung interact if they really invite him ㅋㅋ
8. [+243, -18] I like the current members and format of RM. Song Joong Ki worked hard but he lacks variety skills and barely smiled. They should invite him to guest but I don't want him to come back as a permanent member. He's better off focusing with acting
9. [+152, -17] Even men find In Sung hyungnim attractive
10. [+78, -5] Please invite Ma Dong Seok. I seriously want to see him in a name tag battle with Kim Jong Kook
11. [+54, -4] Get Jo In Sung, Song Joong Ki and Im Joo Hwan to guest in the same episode
