The television series MASH garnered a massive viewership in its eleven-year run from 1972 to 1983. Based on former army surgeon Richard Hooker’s novel MASH: A Novel About Three Army Doctors, the show carefully treads the territory of patriotism and life during wartime. Not everything went smoothly between the network, writers, and cast, and the show was almost canceled entirely after its first season. Fans of the show still enjoy rewatching old episodes and some know every last detail of the show. Are you one of them? Only true MASH fans can pass this quiz- test your knowledge and see how you rank.
