The girls of T-ara were a little tired after filming the music video for "Roly-Poly" for a duration of 30 hours. From the 18th of June to the 19th, the girls stayed up all night filming for the music video for over 24 hours straight. After the tiresome shoot, the girls couldn't help but basically pass out on the couches. Staff on set took some candid shots of the girls sleeping soundly. The sleeping crew includes T-ara's sleepiest member,�Eunjung, as well as Jiyeon, Qri, Boram, and Soyeon. Their company says the new song is a song that will be loved by all ages, so I guess it takes a lot of energy to film the music video for a national song. [gallery columns=4] Source: Newsen via Nate
