In Act II, scene 3, Benedick overhears Don Pedro, Leonato, and Claudio's staged discussion of Beatrice's love for him. He then admits his love for her, and rationalizes it this way:
"I may chance have some odd quirks and remnants of wit broken on me, because I have rail'd so long against marriage. But doth not the appetite alter? A man loves the meat in his youth that he cannot endure in his age. Shall quips and sentences and these paper bullets of the brain awe a man from the career of his humor? No, the world must be peopled. When I said I would die a bachelor, I did not think I should live till I were married."
This is one of the most comic scenes in the play because Benedick's attitude changes so quickly and so violently.
