The startling truth finally became apparent, and it was this: Numbers
written on restaurant checks within the confines of restaurants do not follow
the same mathematical laws as numbers written on any other pieces of paper in
any other parts of the Universe.  This single statement took the scientific
world by storm.  So many mathematical conferences got held in such good
restaurants that many of the finest minds of a generation died of obesity and
heart failure, and the science of mathematics was put back by years.
