I saw an advertisement the other day for the secret of life. It said "The secret of life can be yours for twenty-five shillings. Sent to Secret of Life Institute, Willesden." So I wrote away, seemed a good bargain, secret of life, twenty-five shillings. And I got a letter back saying, "If you think you can get the secret of life for twenty-five shillings, you don't deserve to have it. Send fifty shillings for the secret of life."
