This really happened, in a geography class I took, long ago, in an Arkansas elementary school.
Teacher: “Which state is south of Arkansas?”
Me: “There are six: Oklahoma, Missouri, Tennessee, Mississippi, Louisiana, and Texas.”
Teacher: “No, Robert, that’s wrong.”
Me: “No, YOU’RE wrong. I’m right, and I’ll prove it.” I then got up, walked to the large classroom map of Arkansas, and ran my finger downwards on the map, six times, along the arrows you see above, while shouting, “South! South! South! South! South! South!” It’s true: from some point in Arkansas, you can travel, due South, into some part of any of the six adjacent states.
The teacher called my mother. Her response? “What’s the problem? He was RIGHT, wasn’t he?”
