7. I may not send Ginny one of Hogwarts' toilet seats.

George was trying to think of another prank to do, when suddenly he got an idea.

"Hey Fred," George asked, "Remember when we promised Ginny a toilet seat."

"You're right George," Fred replied, "We must always fulfill our promises." With a grin, the two pranksters went to Moaning Myrtle's bathroom, ignored her shrieks as they pulled out the toilet seat, and managed to convince one of the owls in the owlery to send the toilet seat to the Burrow.

The resulting howler from Molly Weasley would go down in Hogwarts lore.

8. I may not change the password the Slytherin Dungeons to 'Muggleborn'

Fred slipped out of the dungeons chortling with laughter before anyone could see him.

"I take you've done it?" asked George.

"Yup, I've changed the password to Muggleborn, can't wait to see Snape's face." Replied Fred. Soon after, the Slytherins arrived at the tower. Draco Malfoy went up and said confidently

"Pureblood" Nothing happened, he tried again, "Pureblood" Still nothing, now he got really angry, "Open up already, Pureblood" The door didn't open.

"Er, Malfoy," one of the first years asked, "Maybe you should ask the prefects."

"Impossible" he yelled, "our password never changes. But I guess you can go ask the prefects if you want." Just then, a perfectly aimed paper airplane flew in. It said 'Your new password is Muggleborn'

The anger-filled yell of Draco Malfoy could be heard in Gryffindor Tower.

9. I may not convince the house-elves to replace Malfoy's food with raw meat

"Are you sure this is what he will be wanting, sirs," Dobby asked in a confused voice.

"Of course, Dobby, Harry Potter requested it himself," said Fred

"Dobby will do what Harry Potter wants, sirs," Dobby then said enthusiastically.

Fred and George couldn't wait for dinner, and they were happy to see that the house-elves hadn't let him down. In front of Malfoy was raw meat.

"What on earth is this," Malfoy yelled.

"Why, it's ferret food," replied George, "we thought you needed to embrace your inner nature." And with that, he was gone, before Malfoy could yell,

"MY FATHER WILL HEAR ABOUT THIS"

10. I may not use the first years as lab rats.

"Come all, Come all, Work as testers for Weasley's Wizarding Wheezes. One Galleon for every product you test," said the poster on the wall.

"Fred, George," asked Professor McGonagall, "I'm sure you would love to tell me why all the first years are in the hospital wing."

"I have no idea Professor," said George with what he hoped was an innocent look.

"Maybe detention will jog your memory," said Professor McGonagall. "You have detention for a month."

"But Professor," Fred whined,

"Detention with Snape."

11. I may not hire first years to complete my detention. My detentions are to be done alone.

"Are you sure this is okay, Mr. Weasley," asked a nervous first-year.

"Of course it is," replied Fred, "remember we're paying you for this." A little while later, the lines were complete, and Fred and George turned to go. Unfortunately, for them, Professor McGonagall had been watching. She glared at them,

"Since you hate lines so much, I think it would be fair to triple your original punishment. Detention tomorrow, and if you hire any other first-year to do your lines, you'll regret it."

11a. On a related note, I may not get house-elves to complete my detention.

"Are you sure this is a good idea, Fred?" asked George, "She sure was mad yesterday,"

"Ah, Minnie's got a soft spot for us," claimed Fred, "plus, we're making house-elves happy."

"I guess you're right," George conceded, "Look, our lines are already done."

"Us elves are done, sirs," squeaked a house elf, "We is going back now to the kitchens" Fred and George grinned, but before they could move they bumped into McGonagall who was steaming mad.

"If you think it above yourself to do lines, perhaps we need another punishment. You two will clean all of the Great Hall without magic."

"Aw Minnie," Fred protested

McGonagall pretended she hadn't heard him, but her face was turning red.

"If you two get anyone else to do it for you, you two will clean all of Hogwarts by yourself without magic." Then she turned her back and stormed away. Fred elbowed George and whispered,

"Still worth it for the look on her face."

12. I may not ask Filch what house he was in at Hogwarts, for it is extraordinarily cruel. Exceedingly funny, but extraordinarily cruel.

"We have detention with Filch again, "George groaned, "It's so unfair; we didn't do anything."

"But we can still annoy him. I have the perfect idea," remarked Fred.

"What is that?" asked George.

"You'll see," replied Fred cryptically. When they got there, Filch was waiting for them. But before he could tell them their punishment, Fred broke in.

"Hey, Filch, you never told us what house you were in at Hogwarts." Questioned Fred.

Filch almost dropped his broom. Surely he hadn't heard that right.

"Excuse me?"

"You heard me, Filch: What house were you in?" asked Fred grinning. Filch temper started to get out of hand. He snarled,

"Get out." Fred sniggered,

"Are you going to hex us if we don't?" And before Filch could say anything, Fred and George ran out laughing.
