Instructors may reasonably be unwilling to assign challenge problems that are beyond the scope of the syllabus. I somehow feel the opposite and love to give students problems that are slightly beyond their capability, hoping that one or two may fail to resist the tantalization and thereby struggle through them. I benevolently enjoy observing that struggle, and my observations convince me that students’ creativity should in no way be underestimated. Their unorthodox and imaginative solutions make teaching enjoyable. In this paper, I recall three such delightful problems and their creative solutions.

She had not yet learned the idea of a “fictitious force,” yet this is a quick and rigorous way to solve the problem.
