Whilst watching the 1979 movie Being There, and seeing the stately home of the Shirley MacLaine character...
Me: "Jesus. They live in Hogwarts."
Non-Potter #1: "No, it's not. That's the Biltmore House in Asheville, North Carolina."

Non-Potter #1: "The Biltmore is beautiful. You should go."
About ten minutes later...
Non-Potter #2: "That was funny when you said they lived in Hogsworth."
