The Rules are a Lie

Have I mentioned before that I'm a music major?  No?  Okay then.  I'm a music major.  Composer, cartoonist, and general starving artist at your service. 

In any case, I tend to run into a lot of rather bizarre stuff.  Case in point, my first-semester theory teachers, who liked to pretend that music had hard-and-fast rules that lasted now and forever.  Then comes Theory 4, in which all the rules get thrown unceremoniously out the window and we learn, as one student put it, how to speak whale. 

It's not all bad weird, though.  Sometimes we have fun.  The other day my teacher discovered this song, which my class then sung on a Christmas caroling expedition to the Theory 1 class.  So to kick off this holiday season, I'll share it with you. 
And if you don't find it even half as funny as I do, well, I won't be mad.
