This is a classic and always will be. XD I saw this a long time ago and downloaded the actual song. It's pretty good. (Ozone - Numa Numa Iei [Romanian Pop Song]) The American Idle version is pure genius too.
I've seen the original already about 50 times, but still halarious. But I've never seen the American Idle one, halarious.
My friend filmed himself doing that, and then another friend put it on the internet...I wish I knew where it was, it's the funniest thing I've ever seen. Funnier than all the others...
