"I'm Just a Bill" is a Schoolhouse Rock! segment, featuring a song of the same title written by Dave Frishberg. The segment debuted as part of "America Rock", the third season of the Schoolhouse Rock series, in 1975. The song featured in the segment 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.
