I once volunteered for a political campaign in rural Kansas (Senate campaign, IIRC, this was just a local campaign office) and they brought in some young New York political consultant and he called pizza "pie" (it came up because he was ordering some "pies" for the volunteers). The first time he did it everyone looked at one another and started laughing—not to be mean, it was just so unexpected that no-one could help it. I felt kinda bad for him, seemed really taken aback. NOBODY says that in rural Kansas. You don't order a pie, or a pizza pie, you order a pizza.
For most of us in the room it was the first time we'd heard someone in real life call a pizza a pie, except when doing a bad Italian accent and talking about "a pizza-a pie-a" as a joke.
