The philosophy professor teaching a course my friend was taking warned the class he was going to give them a test. When the day came he entered the classroom, wordlessly placed his chair on the table and, turning to the blackboard, wrote, "Prove to me this chair does not exist."

Most of the nervous students began intently scribbling out long dissertations. But one member of the class wrote down just two words, and then handed his paper to the teacher. The professor had to smile when he read the student's answer: "What chair?"
