“By the Blessed Virgin ! Is it possible that your grace is so thickheaded and so short on brains that you cannot see that what I'm telling you is the absolute truth.”

“Didn't i tell you they were only windmills? And someone with windmills on the brain could have failed to see that!”

“Finally, from so little sleeping and so much reading, his brain dried up and he went completely out of his mind.”

“And thus being totally preoccupied, he rode so slowly that the sun was soon glowing with such intense heat that it would have melted his brains, if he'd had any.”

“The most perceptive character in a play is the fool, because the man who wishes to seem simple cannot possibly be a simpleton.”

“Your grace, come back, Señor Don Quixote, I swear to God you're charging sheep !”

“You are a coward by nature, Sancho, said don Quixote, yet to prevent you from claiming I am obstinate and never do as you recommend, just this once I shall take your advice and keep my distance from the fury that so frightens you, but on one condition: never, in life or in death, will you tell anyone that I retreated from this peril out of fear, but rather acceded to your entreaties; and if you say anything else, you will be lying, and I give you the lie from now until then and from then until now, and I affirm that you lie and you will lie whenever you think or say it. and do not answer me back; for the mere thought that I am retreating from peril, especially this peril, which does appear to have some faint shadow of fear about it, is enough to make me take my stand here and await alone not only that Holy Brotherhood whose name you speak in such terror but the brothers of the twwelve tribes of Israel, and the seven Maccabees, and Castor and Pollux, and all the brothers and brotherhoods in the world.”
