Psy (of Gangnam Style fame) is EVERYWHERE in South Korea. Advertisements on television and over the loudspeaker at the grocery store. His face is printed on my fun socks. I even saw his own brand of cologne the other day!
My kids make their own weird parodies of his popular song. For example, little Sarah and Amy enjoyed singing 오빠 방구 스타일 (brother fart style) for several minutes the other day. Oh, Korea.
