I was first exposed to this media virus* a couple of weeks ago, but I forgot about it until earlier today when I saw it again on CNN. I got the song stuck in my head and just had to track it down.
For those who haven't seen it, here's a link: http://uploads.ungrounded.net/206000...3_numanuma.swf
Nicknamed the "Numa Numa Boy" video, it's a webcam video of an unknown individual, possibly Dutch, lip-syncing the pop song "Dragostea Din Tei" by the Romanian boy band O-Zone. The original music video was a big hit on German MTV.
I also found an MP3 of the full version of the song. A warning to those who seek it: it's a major earworm, and very addictive.
I've read that this video was also mentioned on Fox News today.
*media virus: a term that I believe was originally coined by media analyst Douglas Rushkoff. Basically, a piece of media that spreads and behaves more like a virus than traditional broadcasted media. Example: the "Star Wars Kid" video.
