IDEA

        Eight-year-old Sally brought her report card home from school.
Her marks were good...mostly A's and a couple of B's.  However, her
teacher had written across the bottom:

        "Sally is a smart little girl, but she has one fault.  She talks
        too much in school.  I have an idea I am going to try, which I
        think may break her of the habit."

        Sally's dad signed her report card, putting a note on the back:

        "Please let me know if your idea works on Sally because I would
        like to try it out on her mother."
