The tragic romance of the onion and the eye:
Never the twain shall meet without many tears and much heartbreak. You see, a chemical reaction is destined to happen when the onion is peeled, which converts the sulfoxides that make the onion smell so great into sulfenic acid. This acid then becomes a nasty substance with a long name: syn-Propanethial S-oxide, which stings the woebegone eye.
