Deborah Brooks, of Barrington, tops the spelling debate with this: "If GH can stand for P as in hiccough, OUGH for O as in dough, PHTH for T as in phthisis, EIGH for A as in neighbour, TTE for T as in gazette, and EAU for O as in plateau, the right way to spell POTATO should be: ghoughphtheightteeau.
