Psychiatrist Sidney Freedman (
Allan Arbus) is having trouble working after one of his patients, whom he thought he had helped, dies by
suicide. He believes "there's something special" about the 4077th, so he goes to a poker game there one night and decides to remain for several weeks, to work through his feelings. During his time there, he writes a letter addressed to the deceased
Sigmund Freud. In the letter, he describes the members of the 4077th and recalls stories about them; for instance,
Klinger pretends to have been hit in the head by a helicopter blade and speaks only
Arabic, Hawkeye Pierce deals with a bomber pilot who needs to learn the consequences of war, and
Radar processes the accidental death of an ambulance driver, including writing a letter to the dead man's parents. The main 'action' during the camp's downtime is when people are victimized by an unknown practical joker.
B.J. Hunnicutt turns out to be the joker; at one point, he fills
Frank Burns'
air raid bunker with water, coats the eyepieces of Colonel Potter's binoculars with black ink and enlists Sidney's help by having him shout "Air raid!" to lure Frank into the trap. Revitalized, Sidney ultimately departs the 4077th, realizing that happiness is "like springtime at MASH. If you can't see it or find it, you just go ahead and make it", and he's "coaxing a little bud to grow" inside himself. As he drives off, he finds himself the latest target of B.J.'s jokes. ==Production==
