The Chair Test
===============
An eccentric philosophy professor gave a one question final exam
after a semester dealing with a broad array of topics.
The class was already seated and ready to go when the professor
picked up his chair, plopped it on his desk and wrote on the
board: "Using everything we have learned this semester, prove
that this chair does not exist."
Fingers flew, erasers erased, notebooks were filled in furious
fashion. Some students wrote over 30 pages in one hour
attempting to refute the existence of the chair. One member of
the class however, was up and finished in less than a minute.
Weeks later when the grades were posted, the student who finished
in one minute got an A.
The rest of the group wondered how he could have gotten an A when
he had barely written anything at all.
This is what he wrote:
"What chair?"
