End-of-school rhyme

"No more pencils, no more books, no more teacher's dirty looks," is supposedly a traditional jingle sung by American school children at the start of each summer vacation. There are many variations as to the precise wording. The first printed form of this songs is found in the Michigan Education Journal of 1932, where it's implied that the journalist had already heard the song at least 10 years earlier.
