Arriving at the Army training center where Claude is stationed ("Three-Five-Zero-Zero", "Good Morning Starshine"), the hippies are turned away...ostensibly because the base is on alert, but also because the MP on duty doesn't like their looks. (The MP also assumes a condescending attitude toward Berger, caricaturing his perceived vernacular.) Sometime later, Sheila chats up army sergeant Fenton at a local bar. She lures the sergeant, with intimations of sex, to an isolated desert road, acquiring his uniform. The hippies steal Fenton's car, and Berger cuts his hair and puts on the uniform (symbolically becoming a responsible adult), then drives the sergeant's car onto the Army base. He finds Claude and offers to take his place for the next headcount so that Claude can meet Sheila and the others for a going-away picnic they're having for him in the desert.
