See? Betty Botter knew what she was doing. You might have heard of her, albeit rather quickly every time. Betty Botter bought some butter, but she said the butter's bitter. If I put it in my batter, it'll make my batter bitter. So she bought a bit of butter, better than her bitter butter, and she put it in her batter and her batter wasn't bitter. So 'twas better Betty Botter bought a bit of better butter.
