“If you think I'm going to let six people risk their lives - !''because it's the first time for all of us,' said Ron.'This is different, pretending to be me -''Well, none of us really fancy it, Harry,' said Fred earnestly. 'Imagine if something went wrong and we were stuck as specky, scrawny gits forever.'Harry did not smile. 'You can't do it if I don't cooperate, you need me to give you some hair.''Well, that's the plan scuppered,' said George. 'Obviously there's no chance at all of us getting a bit of your hair unless you cooperate.''Yeah, thirteen of us against one bloke who's not allowed to use magic; we've got no chance,' said Fred.”
“Are you trying to weasel out of showing us any of this stuff?' said Zacharias Smith. 'Here's an idea,' said Ron loudly, 'why don't you shut your mouth?' 'Well, we've all turned up to learn from him, and now he's telling us he can't really do any of it,' he said. 'That's not what he said,' said Fred Weasley. 'Would you like us to clean out your ears for you?' inquired George, pulling a long and lethal-looking metal instrument from inside one of the Zonko's bags. 'Or any part of your body, really, we're not fussy where we stick this,' said Fred.”
“You know, I don’t get why Fred and George only got three O.W.L.s each,” said Harry, watching as Fred, George, and Lee collected gold from the eager crowd. “They really know their stuff. . . .”“Oh, they only know flashy stuff that’s no real use to anyone,” said Hermione disparagingly.“No real use?” said Ron in a strained voice. “Hermione, they’ve got about twenty-six Galleons already. . . .”
“Hello, Harry" said George, beaming at him. "We thought we heard your dulcet tones.""You don't want to bottle up your anger like that, Harry, let it all out," said Fred, also beaming. "There might be a couple of people fifty miles away who didn't hear you.”
“Fred, you next," the plump woman said. "I'm not Fred, I'm George," said the boy. "Honestly, woman, you call yourself our mother? Can't you tell I'm George?" "Sorry, George, dear." "Only joking, I am Fred," said the boy and off he went.”
“When we were in Diagon Alley,' Harry began, but Mr. Weasley forstalled him with a grimace.Am I about to discover where you, Ron, and Hermione disappeared to while you were supposed to be in the back room of Fred and George's shop?'How did you...?'Harry, please. You're talking to the man who raised Fred and George.”
