The story centers on a classroom where students are assigned a weekend task to sell something and then give a talk about productive salesmanship. Each student shares their experience, starting with Little Sally who sold Girl Scout cookies and made $30, attributing her success to appealing to customers’ sense of civic duty. Little Jenny sold magazines and earned $45 by highlighting their usefulness in keeping people informed. Then, Little Johnny reveals that he made $2,467 by selling toothbrushes, which astounds the teacher. Johnny explains that he set up a “Dip & Chip” stand at a busy corner, offering free samples of a product that everyone found unappealing, leading to sales of toothbrushes.
