      George Banks was a clever journalist. He worked for a good newspaper, and  he liked arguing

very  much. He argued with anybody, and about anything. Sometimes the people whom he argued

with were as clever as he was, but often they were not.

      He did not mind arguing with stupid people at all: he knew that he could never persuade them to

agree, because they could never really understand what he was saying, and the stupider they were,

the surer they were that they were right; but he often found that stupid people said very amusing things.

     At the end of one argument which George had with one of these less clever people, the man said

some-thing which George has always remembered and which has always amused him. It was, "Well,

Sir, you should never forget this: there are always three answers to every question: you answer, my
