Move over, Justin Bieber, there's a new YouTube favorite in town. South Korean pop artist Psy's catchy dance tune "Gangnam Style" became YouTube's most-watched video on Saturday, registering over 803 million views and squeezing out Bieber's "Baby" from the top spot. Is it because Psy's dance moves are more fun than Bieber's? Because women would rather be Psy's "sexy lady" than Bieber's "baby"? Did Obama's endorsement help? Whatever it is, we now know that China's no threat to American culture. It's South Korea we have to watch out for.
