The most beautiful words in the English language are not "I love you," but "It's benign."

The line plays on a comic reversal of romantic cliché. Instead of elevating “I love you” as the pinnacle of English expression, it crowns the clinical reassurance “It’s benign” as more beautiful—because it signals relief from a feared diagnosis. The humor depends on incongruity (medical jargon treated as poetry) and on a distinctly modern anxiety about health and mortality. In typical Woody Allen fashion, the joke suggests that for a neurotic, mortality-conscious sensibility, survival and the avoidance of catastrophe can feel more profound than conventional declarations of love.
