Game Theory in "The Princess Bride"
by Dirk Mateer `

An amusing battle of wits between two adversaries for princess takes place in a field. In order to resolve their standoff they each agree to drink from a set of goblets, one of which is laced with a lethal poison. What makes the scene especially useful is how it showcases asymmetric information. It turns out that one of the participants has developed a tolerance for the poison so fills both goblets with poison while the other person is distracted. I use this scene to show strategic interaction and asymmetric information while covering game theory in my classes.
