- |============================================================================| The Quote for the day is:
-
- .. Any resemblance between the above views and those of my employer,
- my terminal, or the view out my window are purely coincidental. Any
- resemblance between the above and my own views is non-deterministic.
- The question of the existence of views in the absence of anyone to hold
- them is left as an exercise for the reader. The question of the
- existence of the reader is left as an exercise for the second god
- coefficient. (A discussion of non-orthogonal, non-integral polytheism
- is beyond the scope of this article.)
