I've never seen one of these before, but I was on an OSNN forum page today and all of a sudden some weird "ninja" music started playing. I shut every window on my PC until I realized it was the banner ad at the bottom of the forum! Something about killing ninjas for ringtones . . . anyways it was pretty annoying. Just my 2c, maybe the banner ads here always sing and I just didn't notice it until now.
