Girls' Generation recently uploaded a video proving that it's always a bad idea to fall asleep when your mischievous friends are wide awake!

On February 26, SM Entertainment uploaded a video onto Girls' Generation's official home page that was secretly taken while Jessica was sleeping.  She had fallen asleep when the girls got to take a break during filming.  With a cute pin in her hair, she was completely unaware that another member, who appeared to be Sunny based on the voice, was trying to feed her a Korean snack.

Awakened by this, Jessica laughed and shooed away the camera good-humoredly.  It appears she won't be the last victim of a hidden camera as the girls' home page has a pop-up window that gives sneak peeks at the members through a CCTV.  More fun is sure to come as they upload videos of the other members guerrilla style.
