The Munsters (1964)

S1E6 Low-Cal Munster

Herman is eager to attend a reunion with his military buddies, but he faces a problem—his army uniform no longer fits. Although Lily is hesitant about his trip, she proposes a compromise. She agrees to let him go if he can shed enough pounds to fit back into his uniform. With a weight-loss challenge set, Herman embarks on a journey to slim down for the occasion.
