“Deliberately causing mayhem in Snape's Potions class was about as safe as poking a sleeping dragon in the eye.”

“As Harry and Ron rounded the clump of trees behind which Harry had first heard the dragons roar, a witch leapt out from behind them.It was Rita Skeeter. She was wearing acid-green robes today; the Quick-Quotes Quill in her hand blended perfectly against them."Congratulations, Harry!' she said beaming at him.
