On the September 12th episode of SBS's "HaHaMong Show", KARA's Jiyoung came on as a surprise guest to help 2AM's Jo Kwon and CNBLUE's Yonghwa prepare a special event for - and develop their friendship with�- their SBS Inkigayo co-MC, f(x)'s Sulli. Jiyoung said,

"In order to become closer, you need to have nicknames. For me and Sulli, we call each other by the nicknames 'Egg White' and 'Egg Yolk'. I like egg whites and Sulli likes egg yolks."

To this the MCs HaHa and MC Mong suggested, "Then how about Jung Yonghwa be 'Rinse'�(Conditioner) and Jo Kwon be 'Shampoo'?" Yonghwa replied, "Then Sulli can be 'Treatment'." Jiyoung also revealed a selca photo of herself with Sulli saying, "In order to become closer, you have to take selcas too." Jo Kwon and Yonghwa went on to take a bizarre selca of themselves and brought about a sea of laughter on the set. Also, earlier today Jo Kwon updated his Twitter with a photo of himself and Yonghwa titled,

"We are MC Jo Shampoo & Jung Rinse ~~>_<"

Fans commented, "OMG~ Yoo guys look so sweet~" "Handsome guys! Being good friends, hah!" and "wgm boys. where are your wives? :D"
