“Miss Granger, you foolish girl, how could you think of tackling a mountain troll on your own? Five points will be taken from Gryffindor for this,” said Professor McGonagall. “I’m very disappointed in you.”Hermione left. Professor McGonagall turned to Harry and Ron.“Well, I still say you were lucky, but not many first years could have taken on a full-grown mountain troll. You each win Gryffindor five points.”

“Fifty?” Harry gasped.“Fifty points each,” said Professor McGonagall, breathing heavily.“Professor — please —”“You can’t —”“Don’t tell me what I can and can’t do, Potter. I’ve never been more ashamed of Gryffindor students.”

“That is the second time you have spoken out of turn, Miss Granger,” said Snape coolly. “Five more points from Gryffindor for being an insufferable know-it-all.”

“Lee Jordan was finding it difficult not to take sides.'So — after that obvious and disgusting bit of cheating —''Jordan!' growled Professor McGonagall.'I mean after that open and revolting foul —''Jordan, I'm warning you —''All right, all right. Flint nearly kills the Gryffindor Seeker, which could happen to anyone, I'm sure, so a penalty to Gryffindor, taken by Spinnet, who puts it away, no trouble, and we continue play, Gryffindor still in possession.”

“Hello, Professor McGonagall,” said Moody calmly, bouncing the ferret still higher.“What — what are you doing?” said Professor McGonagall, her eyes following the bouncing ferret’s progress through the air.“Teaching,” said Moody.“Teach — Moody, is that a student?” shrieked Professor McGonagall, the books spilling out of her arms.“Yep,” said Moody.“Moody, we never use Transfiguration as a punishment!” said Professor McGonagall weakly.”

“I think so,' said Professor McGonagall dryly, 'we teachers are rather good at magic, you know.”

“Our Headmaster is taking a short break,' said Professor McGonagall, pointing at the Snape-shaped hole in the window.”
