The Girls' Generation are unique in their ability to tease one another about topics that could appear sensitive to the public, but actually are not.  Their playful demeanor and easygoing personalities always shine in moments like these.

The first episode of their On Style reality program, 'Channel Girls' Generation,' aired on July 21 where the girls had to answer questions during a quiz segment.  A question was asked, "In 2009, Yoona chose three essential conditions for her ideal type; what were they?"

Yuri's mischievous side came out as she replied, "A man who looks good in a suit and shirt," then added, "Lee Seung Gi," making everyone laugh.  Yoona, who was behind her, sat on a chair as if she was feeling shy, grabbing further attention.  

Taeyeon then answered the question with, "Someone tall and considerate who looks good in a suit," while Sooyoung stated, "Someone who looks good in a suit, shirt, and horn-rimmed glasses."

Ding ding ding!  Sooyoung had the correct answer.
