The Duck Variations is a 1972 play by American playwright David Mamet. The play depicts a discussion taking place between two elderly men sitting on a park bench watching ducks. The dialogue begins with the mating habits of ducks and runs to examine law, friendship and death. The principal irony is that the men really know nothing about ducks. If they did, it would not improve their beautiful fugue on the theme of the possibility of happiness. Rather they use what experience has taught them and scattered, possibly incorrect ideas and facts to make guesses. They each assure the other that their guesses are established fact. By argument and occasional agreement a composite view of ducks and by extension, the world, begins to emerge.
