For those who haven’t clawed their eyes out after watching the previous Numa Numa video, there’s an updated version of Numa Numa Dance at Newgrounds or if you don’t like tons of flashing crud in the browser, click on the direct link to the flash.
For those who actually like the song, it’s real name is Dragostera Din Tei by Haiducii/O-Zone. If you’re really addicted to it, there’s several versions up in the iTunes Music Store, including some really horrid English versions.
