Oh Gee! Sunny Makes a Lyrical Mistake

During a recent performance at the Lotte World Free Christmas Concert, Sunny becomes a lyricist as she somehow mixes up her lines during "Gee".
On December 17th the girls of SNSD, or Girls' Generation, performed their hit tracks "Oh!" and "Gee" at the Lotte World Free Christmas Concert only a short while after the special year-end broadcast of KBS's "Music Bank".
Their girls' performance of "Gee" goes slightly awry as Sunny seems to create her own lyrics during her solo lines. The group took her humorous rendition in stride as Yuri laughs noticeably, as well as YoonA and Soo Young, as Sunny cannot help but laugh at her mistake as well.
At the end of the verse Sunny and Yuri have a funny exchange, no doubt laughing over Sunny's new version of "Gee".

Check out the full-length video of SNSD's performance of "Gee" below, where Sunny's mistake can be seen at 7 minutes and 32 seconds. If you listen closely, you can hear that Sunny cleverly inserts her name into the lyrics as well.
