I used to love those in-between-cartoon cartoons they used to run on Saturday mornings... to teach kids grammar and history and the constitution and stuff... Schoolhouse Rock!
this was one of my favorites:
Schoolhouse Rock- How a Bill Becomes a Law
I'm just a bill, yes i'm only a bill, and i'm sitting here on Capitol Hill...
oh and this one too:
School House Rock - No More Kings (America Rock)
