Context: "This is the Improbable Club," said the President-Emeritus in a heavy muffled voice, "and you things have made an improbable entry. Many unqualified persons have attempted to crash this Club, but you have done it literally. Whether you will be able to qualify for our high membership is another thing. It will not matter.
