Cobwebs from an Empty Skull - Ambrose Bierce - Bog

A certain Persian nobleman obtained from a cow gipsy a small oyster. Holding him up by the beard, he addressed him thus: "You must try to forgive me for what I am about to do; and you might as well set about it at once, for you haven't much time. I should never think of swallowing you if it were not so easy; but opportunity is the strongest of all temptations. Besides, I am an orphan, and very hungry."
