“This isn't your average book, it's pure gold: Twelve Fail-Safe Ways to Charm Witches. Explains everything you need to know about girls. IF only I'd had this last year I'd have known exactly how to get rid of Lavender and I would've known how to get going with... Well Fred and George gave me a copy, and I've learned a lot. You'd be surprised, it's not all about wandwork, either.”

“Can't stay long, Mother," he said. "I'm up front, the prefects have got two compartments to themselves-"
"Oh, are you a prefect, Percy?" said one of the twins, with an air of great surprise. "You should have said something, we had no idea."

'Yeah, don't bother to keep in touch,' said George, mounting his own.

Fred looked around at the assembled students, and at the silent, watchful crowd. 'If anyone fancies buying a Portable Swamp, as demonstrated upstairs, come to number ninety-three, Diagon Alley — Weasleys' Wizard Wheezes,' he said in a loud voice, 'Our new premises!'

'Special discounts to Hogwarts students who swear they're going to use our products to get rid of this old bat,' added George, pointing at Professor Umbridge.

'STOP THEM!' shrieked Umbridge, but it was too late. As the Inquisitorial Squad closed in, Fred and George kicked off from the floor, shooting fifteen feet into the air, the iron peg swinging dangerously below. Fred looked across the hall at the poltergeist bobbing on his level above the crowd.

'Give her hell from us, Peeves.'

And Peeves, who Harry had never seen take an order from a student before, swept his belled hat from his head and sprang to a salute as Fred and George wheeled about to tumultuous applause from the students below and sped out of the open front doors into the glorious sunset.”
