A long time ago…like, back in the seventies…a wily ad man and a group of television execs came up with the idea of presenting children with educational content cleverly disguised as cartoons. The series came to be known as “Schoolhouse Rock!” and chances are if you were a rugrat parked in front of a television set on Saturday morning sometime in the seventies or eighties then you caught a few episodes. You might remember some of the words, even. (I still recall “I’m Just a Bill” to this day, although to be honest, it hasn’t helped me much to understand what the heck congress is doing these days…)
