Yep. I concure. Numa Numa was a video of some swedish fat tart lipsynching to some shitty german disco song about midget love, IRCC. It came out about a year or so ago, youtube still has it if you search for numa.
The original pop song was a sort of kids' summer hit all over Europe in the summer two or three years ago. By the time I saw this video, I got an instant mild headache from it, until I started laughing.
