“As they passed the rows of houses they saw through the open doors that men were sweeping and dusting and washing dishes, while the women sat around in groups, gossiping and laughing.What has happened?' the Scarecrow asked a sad-looking man with a bushy beard, who wore an apron and was wheeling a baby carriage along the sidewalk.Why, we've had a revolution, your Majesty -- as you ought to know very well,' replied the man; 'and since you went away the women have been running things to suit themselves. I'm glad you have decided to come back and restore order, for doing housework and minding the children is wearing out the strength of every man in the Emerald City.'Hm!' said the Scarecrow, thoughtfully. 'If it is such hard work as you say, how did the women manage it so easily?'I really do not know,' replied the man, with a deep sigh. 'Perhaps the women are made of cast-iron.”

“The Scarecrow watched the Woodman while he worked and said to him "I cannot think why this wall is here nor what it is made of." "Rest you brains and do not worry about the wall," replied the Woodman, "when we have climbed over it we shall know what is on the other side.”

“Can't you give me brains?" asked the Scarecrow."You don't need them. You are learning something every day. A baby has brains, but it doesn't know much. Experience is the only thing that brings knowledge, and the longer you are on earth the more experience you are sure to get.”

“Scarecrow: I haven't got a brain... only straw. Dorothy: How can you talk if you haven't got a brain? Scarecrow: I don't know... But some people without brains do an awful lot of talking... don't they? Dorothy: Yes, I guess you're right.”

“It must be inconvenient to be made of flesh,' said the Scarecrow, thoughtfully, 'for you must sleep, and eat and drink. However, you have brains, and it is worth a lot of bother to be able to think properly.”

“I think you are a very bad man," said Dorothy."Oh, no, my dear; I'm really a very good man, but I'm a very bad Wizard, I must admit.”

“I think,' said the little Queen, smiling, 'that your friend must be the richest man in all the world.' 'I am,' returned the Scarecrow; 'but not on account of my money. For I consider brains to be far superior to money, in every way. You may have noticed that if one has money without brains, he cannot use it to advantage; but if one has brains without money, they will enable him to live comfortably to the end of days.' 'At the same time,' declared the Tin Woodman, 'you must acknowledge that a good heart is a thing that brains cannot create, and that money cannot buy. Perhaps, after all it is I who am the richest man in all the world.' 'You are both rich, my friends,' said Ozma gently; 'and your riches are the only riches worth having - the riches of content!' - The Marvellous Land Of Oz by L. Frank Baum pg 192 chapter 24”
