f(x)'s Sulli is obsessed with Park Myung Soo

f(x)'s Sulli guested on this week's episode of KBS's "100 Points out of 100" and proved herself to be a hardcore fan of gagman Park Myung Soo. Despite being surrounded by a slew of other castmates, Sulli only burst into laughter over remarks made by the gagman throughout the show.�The cast eventually caught on, leading someone to reveal, "Sulli has always been a fan of Park Myung Soo's. She likes him to the point of obsession." Energized by the boost in ego, Park Myung Soo began overreacting with his adlibs for his new young fan, leading Sulli to not only guffaw with laughter, but actually tear up because she was laughing so hard. Despite Sulli being completely enamored with the gagman, MBLAQ's Lee Joon took the opportunity to express his affections for f(x).�Blushing until his ears grew visibly red, he shyly stated, "I've always loved all of f(x)'s songs."
