Marge decides it's finally time to separate from Homer, and quickly moves on with her life. Homer is initially devastated, but soon stumbles into a romance with a younger woman.
When Homer uses a diagnosis of narcolepsy to be even lazier than usual Marge takes a therapist's advice and kicks him out. Soon he is romancing Candace, the pharmacist from whom he gets his medication, but when he gets to meet her father he gets a shock. This turns out to be a real nightmare.—don @ minifie-1
