Undergraduate students are often interested in applications of economic principles. Although popular television shows and movies are not real-world examples, drawing from these sources can motivate disinterested students and provide a pedagogical tool that enhances instruction. In this article, the authors discuss several basic introductory economic principles that are illustrated by the television show "The Simpsons." Topics include economic reasoning, opportunity cost, incentives, comparative advantage, declining marginal benefit, elasticity, externalities, free-riding, and game theory. The authors provide discussion questions and student worksheets that instructors can use in their own classes. (Contains 1 table, 3 figures, and 11 notes.)
