'At the end of class, all of the students were preparing to leave. All of a sudden, the professor slammed a chair on to his desk. "Your assignment, class, is to write an essay that proves that this chair doesn't exist!"
The students all returned next class to write the essay. They all thought as hard as they could but couldn't write anything. Strangely, within seconds of writing the essay, a student handed his in. Just before the time for the essay ended, all of the students finished scribbling pages and pages of thoughts and handed them in.
When the results came back, only the student who handed his paper in first got an A*. His answer was just two words long: "What chair?"'
