I am totally excited after heard the news. It may be just a rumor but who knows that it will be true, right? I hope that all members of SNSD will appear in the Running Man once again. They are totally funny. I can't wait to see the reaction of the running man members. They have waited for SNSD for so long. The last time they appeared in Running Man are in episode 63 and 64. So I can't wait. I want to see Jessica 'stress~~~', Gwangsoo blushes when he sees Yuri, Haha childish reaction, Kim Jongkok shyness, Yoo Jaesuk big smile, and the excited Big Nose Hyung. But this time I hope Song Jihyo and Song Jongki will appear because it will be good if they are pair up with SNSD members too. 

I am pretty excited about SISTAR too. I think Bora can be a good competitor but she didn't have the chance to show it since SISTAR only appear for just about five minutes in couple episodes ago.

SO DO YOU EXCITED TOO????

P.S.: I DO REALLY HOPE THAT ALL MEMBERS OF SNSD WILL APPEAR TOGETHER IN THE 100TH EPISODE.
