“ The meaning of sex is illustrated by two eponymous heroes of British history, King Edward VII (who flourished in the years before the First World War) and the King Edward variety of potato which has fed the British working class for almost as long). The potato, unlike the royal family, reproduces asexually. Every King Edward potato is identical to every other and each on has the same set of genes as the hoary ancestor of all potatoes bearing that name. This is convenient for the farmer and the grocer, which is why sex is not encouraged among potatoes. ”
