He said so in Even Hand, that he had changed his name. Of course, his real name could be very Italian too, we just don't know.
And don't worry, I was not offended or anything. I was just commenting that I had never heard of that stereotype. The vision of Italians in USA is, I think, somewhat different than the vision of them here where most people has sone Italian ancestry. I remember now that there is an episode of the Simpsons in Italy where Bob Terwilliger and his Italian family wear knives. I never thought there was a relationship between the two things (being Italian and handling knives)
