From Prof. Oddfellow's sketchbook:
The world is figuratively one's oyster, and "the world may undoubtedly
be an oyster, though to whom it would belong, to whom it would be answerable in that capacity, is a great deal less certain. It's something that will have to remain a matter for conjecture until science comes up with a definitive answer." —
