My toils in the quotation field have led me to formulate two or three laws about the way people use and abuse quotations. My first law is: When in doubt, ascribe all quotations to Bernard Shaw - which I don't mean to be taken literally, but as a general observation of the habit people have of attaching remarks to the nearest obvious speaker. Churchill, Wilde, Orson Welles and Alexander Woollcott are other useful figures upon whom to father remarks when you don't know who really said them.
