A superb example of "remixing" for popular culture content. While not, obviously, licensed for remixing (via Creative Commons or alternative), this parody (consistent with fair use of copyrighted materials) still showcases tactics involved in remixing (e.g., excerpting, re-sequencing, adding content elements) in a way that creates a new work from the old.
