My idea of heaven is a great big baked potato and someone to share it with.

The line uses homely, comic specificity—“a great big baked potato”—to deflate grand, abstract notions of paradise and replace them with something tangible and comforting. “Heaven” becomes not luxury or spectacle but simple nourishment paired with companionship. The second half, “someone to share it with,” shifts the emphasis from the food to relationship: pleasure is incomplete without connection, and abundance matters less than intimacy. Read this way, the quote functions as a miniature philosophy of contentment—gratitude for ordinary comforts and the primacy of shared experience over solitary indulgence.
