Girls' Generation held a "Party" of their own at their showcase event to promote their new summer hit and the more low-key, groovy R&B jam "Check".

After revealing "Check" through a live performance, Tiffany explained a little bit more about the concept behind the new track. She said, "It's a cool song about girls checking each others's lip stick and shoes before a night out." 

Naturally, the girl group was then asked by MC Shin Dong Yup, "What do you guys actually check before going out?", which prompted a variety of answers--some practical and some hilarious. Hyoyeon answered, "I check if I have money in my purse," Sooyoung said, "I check if I have pepper flakes stuck in my teeth," YoonA said, "If I wore my shoes correctly," Taeyeon said, "If I remembered to pack perfume," and Tiffany answered, "If I fed my dog." 

The irresistibly cute member Sunny gave the funniest response of all as she confessed, "I check if the crown of my head smells," and showed how she can smell the top of her head. The other members, who were disgusted by Sunny's act, correctly predicted, "There are going to be articles about this."
