I think someone has posted that before (maybe more than one someone), but it's always fun to see. It kind of demonstrates how fundamental it is that it shows up more than once. My favorite educational music video is Donald Duck in Mathmagic Land. I saw it for the first time when I was a little kid and it set a good foundation for understanding how notes work. It also had a section on how to shoot pool. I never got any good at pool but it helped my air hockey game quite a bit.
