“People in Hillsboro are smarter than people in Chicago. Do you know why?”

 Since I had just moved to Hillsboro from Chicago, I took the bait. “No idea,” I said to my new neighbor, “Why are people in Hillsboro smarter than people in Chicago?”

 “Because,” he said, “everyone in Hillsboro knows where Chicago is, but no one in Chicago knows where Hillsboro is.”
