Harry Truman, when he was U.S President, once addressed the Washington Garden Club and kept referring to 'good manure' that must be used on flowers.
Some society ladies complained (later) to the First Lady Margaret Truman, "Bess, can't you get the President to say fertilizers?"
The First Lady replied, "Heavens, it took me 25 years to get him to say 'manure'".
