When I got home from work last night my wife told me about my 2 year old son's new game. He takes a bunch of blocks and lines them up on the floor, then gets his ukelele. Then he'll start strumming away and singing while he stomps his "pedals" on and off. He'll occasionally crouch down and fiddle with the pretend knobs, and then keep on jamming...usually to Uncle John's Band, or Neko Case's This Tornado Loves You. I was almost as proud as the day he learned the word "capacitor".
