As a child, US president William H Taft had a habit of mispronouncing words, with the letter S being a real problem. When he became governor of the Phillipines, he was given a course of what we would now call 'speech therapy', but he continued to say certain words wrongly, often not realising he was doing so. In particular, throughout his life he said 'snossage' instead of sausage, which was a problem since Taft was fond of the foodstuff, and was occasionally nicknamed 'Bolony Bill'! All aides who worked with Taft during his term in the White House were warned of his occasional lexical idiosyncrasies and strictly ordered not to snigger.
