UPDATE: I've removed the link, since the video's been taken down -- as has an earlier example of "literal video," which you've probably also seen. The earlier one used "Take On Me," and the one I'd linked here used "Under the Bridge." You saw the band's original video and heard the instruments, but the song was re-sung with lyrics that told you what was happening in the video -- like "now superimpose on me someone's ugly house...." It was very funny, and in both cases, it reminded us of an excellent music video and made us re-experience song, look at the video close closely, and enjoy everything in both the old way and an inventive new way.
UPDATE 2: But wait! Reading the Wikipedia entry for "Take On Me," I find the "Funny or Die" page with the video -- which is by Dustin McLean -- and must have been done with permission. Here. And now I can get the "Under the Bridge" one: Here! Yay!
Here's a link to the DustFilms page in "Funny or Die."
