P. G. Wodehouse,
Psmith, Journalist — Chapter 8
(1912)
“ Psmith sighed."Some time ago," he said, "—how long it seems!—I remember saying to a young friend of mine of the name of Spiller, 'Comrade Spiller, never confuse the unusual with the impossible.' It is my guiding rule in life. It is unusual for the substitute-editor of a weekly paper to do a Captain Kidd act and take entire command of the journal on his own account; but is it impossible? Alas no. Comrade Windsor has done it. That is where you, Comrade Asher, and you, gentlemen, have landed yourselves squarely in the broth. You have confused the unusual with the impossible." ”
