what's your function?

Early Wednesday morning whilst running to catch the Transbay bus I misjudged the curb and went skidding across the gravel on Ward near Market, ripping open my jeans and gloves and sustaining some pretty serious damage to my knee and hand in the process.  So rather than going out at night I've been doing a lot of sitting around and nursing my banged-up body since then, but on the positive side my injuries gave me an excuse to watch all two-and-a-half hours of the Schoolhouse Rock! 30th anniversary DVD in one go.  I still can sing along to many of the songs that wedged themselves into my head during my childhood, particularly America Rock classics like "Elbow Room" and "The Shot Heard 'Round the World".  My favorites are the grammar and science segments though, even if I suspect characters like the Conjunction Junction engineer and Interplanet Janet were more memorable than the educational information itself.  And as an adult I can appreciate how amazingly cool it is that they got Blossom Dearie to sing about adjectives and The Tokens to doo-wop about gravity.
