Dr Jones is a senior maths teacher, so has no problem spotting when his wife goes on a spending spree with their credit card. He gives his shapely wife a sound spanking for her efforts but it seems to achieve little more than indignation from her. Next day, he takes her to school and makes her dress up as one of his students. A brisk application of the cane to her bottom, and she realises it hurts a lot more than the spanking. Time for reform!
