Earlier this month, we revealed a CF from Korean petroleum and refinery company, 'S-OIL', which featured an appearance from IU. Two weeks down the road, S-OIL released another CF with IU, and it's actually pretty hilarious. The CF sees IU competing against five boys in a ping pong grudge match, being outnumbered 1:5. After getting smashed in the first few rounds, IU whips out her ukelele and proceeds to smack the living daylights out of the five boys, reducing them to a broken force. Director Park Yong Jin commented, "We planned a fun video with IU to have S-Oil's 2011 campaign more familiar with the public through real emotional stories regarding the celebrity's families. We hope that IU's cute ping-pong play will spread awareness of the good energy of S-Oil." How that has anything to do with S-OIL, we really don't know, but enjoy the CF anyway! Tip: Matt
