"Goodbye, Farewell and Amen" was a two-and-a-half hour TV movie that served as the series finale for M*A*S*H, the iconic series about army doctors serving in the South Korea. The episode, directed by series star Alan Alda, chronicled the last days of the Korean War and the final moments of the beloved 4077th Mobile Army Surgical Hospital. The finale is still one of the highest-rated television episodes of all time.
Throughout the episode, Alda's character Hawkeye teases his long-time friend B.J. Hunnicutt about B.J.'s inability to say "goodbye." The two share an emotional farewell, but it's not until Hawkeye boards a chopper to go home and leave the 4077th for the last time that he sees that B.J. left him a message. "Goodbye" is spelled out in large stones on the helipad.
