Catalog log
Broadcast listing — not a TV Flash recap.
With supplies low, the 4077th gets a truckload of ice cream churns and salt tablets. But what it needs are light bulbs, and in the dimly lit post-op Charles makes an error for which he draws the ultimate wrath of his two surgeon bunkmates. Meanwhile, B.J. receives a mystery novel that everyone in camp reads in turn. The last page is missing and the solution to the mystery is undiscovered until B.J. calls the author by long distance.

Why this series still plays
Eleven seasons of a network comedy that kept rewriting its own permission slip — Korea as the set, Vietnam as the aftertaste, and a goodbye still quoted whenever someone needs proof a sitcom can stop the country.
February 28, 1983, CBS did not program a sitcom. It programmed weather. Goodbye, Farewell and Amen ate the night, the morning papers, and a ratings myth executives still quote like scripture — a two-and-a-half-hour close on a Korean War tent America had been visiting since September 1972. The helicopters were already folklore. The laugh track, by then, had learned when to shut up. On the palate: canvas, cigarette haze, and a three-act clock that could turn a punchline into a casualty without changing the lighting.
