SNSD is back together for a new CF, this time for Ace Bed. Yoona is seen having trouble falling asleep as she rolls around in her bed, tossing and turning. She complains, “Beds really do need to be scientifically designed.” Actor Lee Sunkyun (Pasta, Coffee Prince) makes an entrance and readily agrees, “Of course! Being fully rested even if you don’t sleep for long, that’s science.”

The entire group chimes in, “A bed isn’t just furniture~!” Lee Sunkyun introduces the bed, “The science of beds, Ace Bed.” Satisfied, SNSD ends the CF with “Have a good jam (sleep).”
