Not saying it the "American" way doesn't bother me so much as him inventing a new word that is completely different from the real word's phonetic quality in any language. Hell, even Italians have called into the show to make fun of the way he says it. For example, there's no soft "A" sound at the end of his word. What is it, a silent A?I don't know any 100% Italians who say it the "American way".
This goes for EVERYBODY on the show: "The fact of the matter is".
