“Welcome to a new year at Hogwarts! Before we begin our banquet, I would like to say a few words. And here they are: Nitwit! Blubber! Oddment! Tweak!”
“Albus Dumbledore had gotten to his feet. He was beaming at the students, his arms opened wide, as if nothing could have pleased him more than to see them all there."Welcome!" he said. "Welcome to a new year at Hogwarts! Before we begin our banquet, I would like to say a few words. And here they are: Nitwit! Blubber! Oddment! Tweak!""Thank you!"He sat back down. Everybody clapped and cheered. Harry didn't know whether to laugh or not.“Is he — a bit mad?” he asked Percy uncertainly."Mad?" said Percy airily. "He's a genius! Best wizard in the world! But he is a bit mad, yes. Potatoes, Harry?”
“Nitwit! Blubber! Oddment! Tweak!”
“Odd words floated back to them over the hundreds of heads. "Nobility of spirit"..."intellectual contribution"..."greatness of heart"...It did not mean very much. It had little to do with Dumbledore as Harry had known him. He suddenly remembered Dumbledore's idea of a few words, "nitwit," "oddment," "blubber," and "tweak," and again had to suppress a grin...”
“I don't know who this 'everybody' is that you speak of, but I am beginning to suspect that the Hogwarts you believe you know is not the Hogwarts we currently occupy. Now come here.”
“We could mate. In a year our nestlings would be large enough to mob anyone we like...Should I begin to court you? Do you like grubs or ants better?...I will be here. In case you change your mind about mating.”
