Randall Munroe knows how hard it is these days to select your college major. He wrote a little song about it ...well, he wrote a comic about it that you can sing to the tune of "I Am the Very Model of a Modern Major-General." There are three verses in total, which you can see at xkcd. Link -via Bad Astronomy
Update: Errol actually sang it!
