比尔来自《摇滚校园》

　　Schoolhouse Rock was a set of animated shorts that helped educate kids in the '60s and '70s about conjunctions, the magic number three and, especially the legislative process. The latter lesson starred a rolled-up paper named Bill, and showed how he went from the House to the Senate and eventually became a law. The award-winning educational series was the result of a partnership between Michael Eisner, former chairman of the board at Walt Disney Company, and cartoon legend Chuck Jones. The original series aired from 1973 to 1985.
