Chair?
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 rest of
the group wondered how he could have gotten an A
when he had barely written anything at all. His answer
consisted of two words:
"What chair?"
