The 4077th takes advantage of a temporary lull in shooting to participate in an Army-Navy football game. The festivities come to a sudden halt when an artillery shell lands upon the football field -- and doesn't explode. As everyone else in camp takes cover, Hawkeye and Trapper nervously attempt to disarm the shell, using an outdated manual as their guide. A classic denouement caps this hilariously harrowing M*A*S*H episode, which was co-scripted by series regular
McLean Stevenson, and was first shown on February 25, 1973. ~ Hal Erickson, All Movie Guide
