Disclamer: I don't own Harry Potter and associates, nor do I own the 50 things not to do, I just read them one night with my two roommates and decided to write a fic from them. I do own Carrie, Jen, and Linda.

Chapter 1

In the halls of Hogwarts, three students were tired of playing by the rules. These three girls were an unlikely combination of Gryffindor, Ravenclaw, and Slytherin, they were the best of friends. To their teachers, each was known as polite and inteligent, which for the Gryffindor and Ravenclaw was only to be expected, but a suprise to find in the Slytherin girl. Tired of hearing all about the glory of Harry Potter, the problems of Draco Malfoy, and all the other popular students of Hogwarts, and even Voldemort, the three girls decided to turn Hogwarts upside down.

It was deep in the library, late one night, when the three girls planned out their actions for their pranks. Carrie, the Slytherin, put the finishing touches on the parchment before her and her two friends. The other two, Jen, the Gryffindor, and Linda, the Ravenclaw, both looked over the list and agreed that those would be the best pranks to play around the school.

"You guys ready? We'll start tomorrow and spilt them up." Carrie quickly did the multiplier spell, and made two copies of the list, and handed them to her friends.

"Girls, it's curfew, you need to leave now. The library opens at 6:30 if you wish to come back in the morning." The Librarian said, then continuing on her journey around the library to tell the other students about the time, around the large room.

The three girls got up, shared a smile, then walked to their prespective common rooms to get some sleep before they set their plans into action.

Next Morning

Carrie was eating her oat meal at the Slytherin table, when she heard Jen yell. Turning around to look over at the Gryffindor table, only to laugh as she screamed that Seamus, who was walking behind her at the moment, was "after me lucky charms." Carrie and Linda, who was at the other table, bust out laughing, as the other students, looked at the three oddly.

After breakfast, Carrie caught up with Jen, they had the next class together. They waved goodbye to Linda, and skipped off to Defense Against the Dark Arts. Takeing their seats at the front of the class they waited for the rest of their houses to make their way into the room.

"How did a little traitor like you ever get into Slytherin, Carrie? Hanging out with Gryffindors, that's just wrong." Draco drawled as he came into the room to sit behind the girls, so that he was in a good positon to kick the back of their chairs during class.

Carrie and Jen turned around to respond to the annoying boy, "Draco, my dear, dear boy. Prince of my house," as this point in Carrie's speech, Draco was starting to get curious, she had never taken anything he said this well, "make like a ferret and bounce, ok sweety?" She finished with a grin and a quick high five to Jen.

They watched as Draco tried to say something, gasping for a response, when their favorite teacher came in. Both of the girls turned back around to the front of the classroom to await Professor Lupin's instructions of the day. He was rather pale towards the end of explaining what spell we were supposed to be learning that day.

Jen decided to take advantage when the student's got up to start practicing the spell. She came and put her hand on his arm, then asked real seriosly, "Professor, you look rather pale. Is it you time of the month? I get cramps really bad too, well for different reasons, but I bet Midol will work for you as well." It was good thing that the giggling Carrie was the only one to over hear what Jen said as Professor Lupin stared at the two with bugging eyes and open mouth. Jen took the moment of silence to give the professor a comforting hug, then moved off to practice with the still giggling Carrie.

Later that day at lunch the two caught back up with Linda, and told her of their previous fun having at the expense of Draco and Lupin.

"That's cool and all, but I really want to do something now!" Said the poor left out girl.

"Well, Linda...look at the list and pick one, if you need our help, we'll give it to you." Carrie said, as she and Jen started to eat waiting for her to pick a prank.

Suddenly she looked up with a mad gleam in her eyes. "Guys, I have the perfect one to do, and I will needd your help, as I'm not in the right house for it." She told the two girls what they needed to do, and both agreed to Linda's plan as it was a sound one, and both loved to play with people.

"Ok, we'll get them ready for tomorrow, but in the mean time, I went ahead and made the notices for the Ravenclaw commenroom, which you'll need to post Linda, and the one for Jen to give to Hermione." The two girls read over Carrie's notes

Until Further Notice

The Library will be closed for an indefinite time.

Until then, have fun,

Albus Dumbledore

and cracked up, knowing what wouold happen in the morning when the intendeds found out. "You two will have to tell me how they took the notes in the morning. Till then girls! I have some Hufflepuffs I need to play with, with a spoon and some bees, take care." She parted from the other two with a grin, and all were looking forward to tomorrows fun.
