Oh yes, I love this topic!
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..."
As though an invisible hand were writing upon it, words appeared on the smooth surface of the map. "Mr. Moony presents his compliments to Professor Snape, and begs him to keep his abnormally large nose out of other people's business."
Snape froze. Harry stared, dumbstruck, at the message. But the map didn't stop there. More writing was appearing beneath the first.
"Mr. Prongs agrees with Mr. Moony, and would like to add that Professor Snape is an ugly git."
It would have been funny if the situation hadn't been so serious. And there was more...
"Mr. Padfoot would like to register his astonishment that an idiot like that ever became a professor."
Harry closed his eyes in horror. When he'd opened them, the map had had its last word.
"Mr. Wormtail bids Professor Snape good day, and advises him to wash his hair, the slimeball."
"Harry!" said Fred, elbowing Percy out of the way and bowing deeply. "Simply splendid to see you, old boy-"
"Marvelous," said George, pushing Fred aside and seizing Harry's hand in turn. "Absolutely spiffing." Percy scowled.
"That's enough, now," said Mrs. Weasley.
"Mum!" said Fred as though he'd only just spotted her and seized her hand too. "How really corking to see you-"
"How're we getting to King's Cross tomorrow, Dad?" asked Fred as they dug into a sumptuous pudding.
"The Ministry's providing a couple of cars," said Mr. Weasley.
Everyone looked up at him.
"Why?" said Percy curiously.
"It's because of you, Perce," said George seriously. "And there'll be little flags on the hoods, with HB on them-"
"-for Humongous Bighead," said Fred.
"Don't be prat, Neville, that's illegal," said George. "They wouldn't use the Cruciatus Curse on the champions. I thought it sounded a bit like Percy singing... maybe you've got to attack him while he's in the shower, Harry."
"You two," she went on, gazing down at Fred and George, "are about to learn what happens to wrongdoers in my school."
"You know what?" said Fred. "I don't think we are."
He turned to his twin.
"George," said Fred, "I think we've outgrown a full-time education."
"Yeah, I've been feeling that way myself," said George lightly.
"Time to test our talents in the real world, d'you reckon?" asked Fred.
"Definitely," said George.
And before Umbridge could say a word, they raised their wants and said together, "Accio Brooms!"
Harry heard a loud crash somewhere in the distance. Looking to his left he ducked just in time -- Fred and George's broomsticks, one still trailing the heavy chain and iron peg with which Umbridge had fastened them to the wall, were hurtling along the corridor toward their owners. They turned left, streaked down the stairs, and stopped sharply in front of the twins, the chain clattering loudly on the flagged stone floor.
"We won't be seeing you," Fred told Professor Umbridge, swinging his leg over his broomstick.
"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 anybody fancies buying a Portable Swamp, as demonstrated upstairs, come to number ninety-three Diagon Alley - Weasley's 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," said 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, whom 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.
"Is Bill here?" he (Harry) asked. "I thought he was working in Egypt."
"He applied for a desk job so he could home and work for the Order," said Fred. "He says he misses the tombs, but," he smirked. "there are compensations..."
"What d'you mean?"
"Remember old Fleur Delacour?" said George. "She's got a job at Gringotts to eemprove 'er Eeenglish-"
"-and Bill's been giving her a lot of private lessons," sniggered Fred.
"...Little Ronnie, a prefect...Oh, I'm all of a dither!" She gave Ron yet another kiss on the cheek, sniffed loudly, and bustled from the room Fred and George exchanged looks.
"You don't mind if we don't kiss you, do you, Ron?" said Fred in a falsely anxious voice.
"We could curtsy, if you like," said George.
"How do you feel Georgie?" whispered Mrs.Weasley.
George's fingers groped for the side of his head."Saintlike," he murmured.
"What's wrong with him?" croaked Fred, looking terrified. "Is his mind affected?"
"Saintlike," reapted George, opening his eyes and looking up at his nrother. "You see...I'm holy. Holey, Fred, geddit?"
Mrs.Weasley sobbed harder than ever. Color flooded Fred's pale face.
"Pathetic," he told George. "Pathetic! With the whole world of ear-related humor before you, you go for holey?"
"Ah well," said George, grinning at his tear-soaked mother. "You'll be able to tell us apart now, anyway, mum."
When he straightened up again, there were six Harry Potters gasping and panting in front of him. Fred and George turned to each other and said together, "Wow -- We're identical!"
"I dunno, though, I think I'm still better looking" said Fred
"And the rumors that he keeps being sighted abroad?" asked Lee.
"Well, who wouldn't want a nice little holiday after all the hard work he's been putting in?" asked Fred. "Point is, people, don't get lulled into a false sense of security, thinking that he's out of the country. Maybe he is, maybe he isn't, but the fact remains he can move faster than Severus Snape confronted with shampoo when he wants to, so don't count on him being a long way away if you're planning on taking any risks. I never thought I'd hear myself say it, but safety first!"
I think it's enough for now.
