Girls' Generation appeared on KBS 2TV's 'Yoo Hee Yeol's Sketchbook' on September 5!

During the interview portion, they were asked what kind of concept they wanted to try, and Sooyoung answered, "I don't think it'd be bad to do something more like a 'Moulin Rouge' concept to suit our age.  A little bit more matured, but this doesn't mean that the exposure would be extreme, rather the performance; for example, we would come down on a tightrope or try a professional performance."

The girls also talked about the Christmas special for the show, stating that they wanted to appear on one of those.  YoonA said, "All of the members ate chicken while watching 'Yoo Hee Yeol's Sketchbook' Christmas special together.  We wondered how it would be if we came out on that, too.  Why didn't you call us over?  We were upset."

Previously, SISTAR had appeared on the Christmas special and had fun ruining their image in furry outfits.  

Sooyoung said, "Stuff like that is our specialty," while Seohyun added, "I really want to try that."
