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 prof 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, blue books 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 rest of the group wondered
how
he could have gotten an A when he had barely written anything at all.
What
did he write, they asked.
"What chair?"
