Since Bunny is such the musical buff that she is, she might get a kick out of this instructional video: How to Write a Fugue [1], based on Brittney Spears' [2] “Oops I Did It Again [3].”
Not only is it an instructional video on constructing a fugue based on a pop song, the video itself is a fugue, and to understand that, you have to watch the video.
