“ Next morning the Scarecrow said to his friends:
"Congratulate me. I am going to Oz to get my brains at last. When I return I shall be as other men are."
"I have always liked you as you were," said Dorothy simply.
"It is kind of you to like a Scarecrow," he replied. "But surely you will think more of me when you hear the splendid thoughts my new brain is going to turn out." ”

“ The Scarecrow went in and found the little man sitting down by the window, engaged in deep thought.
"I have come for my brains," remarked the Scarecrow, a little uneasily.
"Oh, yes; sit down in that chair, please," replied Oz. "You must excuse me for taking your head off, but I shall have to do it in order to put your brains in their proper place."
"That's all right," said the Scarecrow. "You are quite welcome to take my head off, as long as it will be a better one when you put it on again." ”

“ When he had fastened the Scarecrow's head on his body again he said to him, "Hereafter you will be a great man, for I have given you a lot of bran-new brains."
The Scarecrow was both pleased and proud at the fulfillment of his greatest wish, and having thanked Oz warmly he went back to his friends.
Dorothy looked at him curiously. His head was quite bulged out at the top with brains.
"How do you feel?" she asked.
"I feel wise indeed," he answered earnestly. "When I get used to my brains I shall know everything." ”
