Fred and George Weasley, the clowns of Hogwarts School of Witchcraft and Wizardry's favourite victim for pranks was Argus the Filch the shrub caretaker. They had played so many pranks and had lost so many house points to McGonagall, but mostly Snape. But this prank was worth losing all the points they had received today after Harry had won the Quidditch match.

They were in the Second Floor Corridor at the wall where the message from the heir of Slytherin was written last year. They had with them, a rat.

"Not Scabbers now is it?" asked Fred as George picked him up by the tail.

"Nah," he said. "But it would be funny to see how Ron would react."

Fred chortled as he got out a bottle of Polyjuice Potion. He put the bottle to the rat's mouth.

The mouse grew bigger and bigger and fluffier and fluffier until George was holding Mr. Filch's cat, Mrs. Norris.

"Petrificus Totalus!" demanded Fred. As soon as the cat was as still as a statue, they curled its tail onto the torch bracket where Mrs. Norris was hooked and waited for Filch.

"Blasted students!" they heard. "Their rotten dungbombs"

George threw a stone to a suit of armer to get the squib's attention and Filch looked down the corridor!

"AAAAAAH!" he screamed "MRS. NORRIS!"

He ran down to the corridor where she hung. he tried to reach for her but it was too high.

The twins came out laughing as the spell on the cat wore off and explained ot was really a rat.

Professor McGonagall gave them a month's detention with Professor Sprout and lost thirty points from Gryffindor, but when they entered the common room, they whole of their house were laughing their heads off and applauding, except Hermione and Percy.

"Mum's gonna give you a real howler!" chortled Ron.

"You two should apply for Gambol and Japes!" laughed Lee Jordan.

"You never get on with Filch do you?" sniggered Harry.

"You should both be ashamed of yourselves!" said Hermione crossly. "You could have made people believe that the chamber was reopened by Sirius Black!

"Next time we'll use Crookshanks," said George proudly.

Not to boast, but I think this idea was pretty funny. Please review. Everyone's entitled to their own opinion. xxx.
