On the August 11 edition of On Style's 'Channel Girls' Generation,' Tiffany, who came from the United States when she was young to debut under SM, judged her own Korean skills.

She said, "My Korean skills are above average."  The members agreed, stating, "Tiffany got a lot better at Korean to the point she can write lyrics in Korean."  She then had to do a Korean quiz to test this out more concretely, which caused lots of laughs, especially as the other members also had to match what certain acronyms or words meant.

Upon Taeyeon's fail moment, everybody laughed and Tiffany asked her, "Did you come here from America?"  Taeyeon replied to further everyone's amusement, "I came from Jeonju."
