“I’m Just a Bill” is a classic Schoolhouse Rock! segment which first aired in 1975. It is sung by Jack Sheldon (the voice of the bill) and his son (the boy learning the process). It is about how a bill becomes a law, how it must go through Congress, and how it can be vetoed, etc. The bill is for the law that school buses must stop at train crossings. In the end, the bill becomes a law.
