I haven't seen that video. (That Guy with glasses site doesn't really work for me for some reason.) And I couldn't find it on Youtube (where I watch all of my NC videos). But I would have to say the rapping dog song from Titanic: The Legend Goes On. It was just so stupid, and out of place.
Ever try going to blip.tv? That's where all sorts of these videos are uploaded to first.
The rapping dog song from Titanic wasn't on the list. I commented about that on the video and he said he completely forgot about that song, otherwise he would have put it up in the list.
