Como se dice "pizza" en Italiano

On Wednesday evening as we were driving to Chuck E' Cheese Tyler decides to go all foreign on Ethan and myself and teaching us something about the Italian language.  He says,  "Dad I know how to say pizza in Italian."  I think to myself and then say to him, "Well...how?"  Tyler says,  "Spaghetti is how you say pizza in Italian."  I love Tyler and the cute things that he says.
