From an interview in the San Francisco Chronicle with Christopher Herb Caen, Herb Caen's son:
Q. When you were a kid, what did you want to be?
A. When I was very young, I was at a birthday party. My mom was going around the table saying, "What do you want to be when you grow up?" Kids were saying: "An astronaut," "A fireman," "A policeman." I said, "An Italian."
