Nitwit! Blubber! Oddment! Tweak! - J.K. Rowling, Harry Potter and the Sorcerer's Stone

"Your mother died to save you. If there is one thing Voldemort cannot understand, it is love. Love as powerful as your mother's for you leaves it's own mark. To have been loved so deeply, even though the person who loved us is gone, will give us some protection forever."

"What happened down in the dungeons between you and Professor Quirrell is a complete secret, so, naturally the whole school knows."

"He didn't realize that love as powerful as your mother's for you leaves its own mark."

"So light a fire!"Harry choked. "Yes...of course...but there's no wood!"... "HAVE YOU GONE MAD!"Ron bellowed. "ARE YOU A WITCH OR NOT!"

"Do you mean ter tell me,"he growled at the Dursleys, "that this boy—this boy!—knows nothin' abou'—about ANYTHING?"Harry thought this was going a bit far. He had been to school, after all, and his marks weren't bad."I know some things,"he said. "I can, you know, do math and stuff."
