"Oh you two are in trouble this time. Once these forms are filled out and I have enough of them I will get permission to hang you up in the dungeons, oh yes," the old man quivered, his arched posture bent over one of a series of rusted cabinets.

George snickered, watching his brother mock the old man behind his back.

Filch turned around and Fred quickly leaned upon the wall, absent-mindedly rubbing his neck.

Filch scowled even further, which one would think was impossible, but surprising both boys the caretaker found it manageable.

As he turned around once more, George looked to the left, raising an eyebrow before looking back at his brother and nodding his head in the direction of the cabinet he had spotted.

Fred's head snapped over, and a smirk rose on his young face.

Before the heads of the two twins lay a drawer marked Confiscated and Highly Dangerous.

"Wicked" ran through both minds.

George quietly reached into his product, and once again snuck a glance at his brother, who quickly nodded his head.

George threw the dungbomb in the direction of the caretaker, and darted out of the room, hearing the opening and closing of a drawer before his brother followed him out.

The pair raced up to the common room, nearly falling in the portrait hole after puffing out the password.

They stumbled up the stairs to the dorm, collapsing on George's bed.

"What'd you get Freddie?" George asked, his eyes bright with curiosity.

Fred's face was slightly disappointed as he raised up an old piece of parchment.

"Parchment?" George questioned.

Fred sighed, throwing it to the side and collapsing back on the bed, hands on his head.

"No point in giving up now, Freddie, you never know!"

Dropping his hands down, Fred sat up once more. "You're right Georgie. Filch may be an idiot sometimes, but he wouldn't confiscate just random parchment."

"What do you think we can do to it?"

"Ask it nicely?" Fred chuckled.

George placed his splintered wand on the parchment. "Please open," he spoke clearly, grinning at his laughing twin.

Both boys quickly stopped laughing however, when words appeared on the parchment before them.

Messrs Moony, Wormtail, Padfoot and Prongs would like to say nice try, but it's not that simple, we swear.

Both eyes glinted as they looked at each other, evil grins appearing on their faces.

"Will we get in trouble for this?" Fred asked, wand on the parchment.

Mr Moony would like to say he should really not be endorsing trouble of any sorts, yet Mr Padfoot presents that perhaps the boys will not be in trouble, but are rather up to no good.

"George."

"Yes Fred."

"Do you think it's trying to tell us something," he grinned again.

"Do you think there might be, well, a password of sorts?" George asked his brother.

"Why yes Georgie, I think there just may be."

Pressing his wand against the parchment, George spoke clearly, "I promise that we are up to no good."

Mr Prongs would like to congratulate the young one on his guess, yet only one person should be able to open this at once.

"I promise that I am up to no good?" Fred questioned.

Mr Wormtail appreciates the effort, but indeed believes something a little stronger may be more efficient.

The two eleven year olds grinned at each other once more, over the Christmas holidays their oldest brother Bill, in conjunction with slightly younger Charlie had taught the twins, and their nine year old brother Ron an abundance of swear words.

"Blimey I cross my heart I am up to no good."

"I bloody well promise I am up to no good."

As the two went on, each time they were wrong, and each time the words used got slightly more inappropriate.

Eventually it came back to Mr Moony, with a very strict response.

Mr Moony requests that these two wash out their mouths with soap before they speak to their mother once more.

Whereas upon the same line, causing the two young trouble makers to laugh greatly, was Mr Padfoot.

Mr Padfoot commends the young Messrs on their creative use of language, but recommends they swear in other manners.

"Cryptic, this lot aren't they," sighed Fred, leaning back against the post.

"Very," George replied, shaking his head. "Come on though Freddie, we're Weasley's, we don't give up."

"I honestly swear I am up to no good."

Mr Wormtail is incredibly impressed with the young Messrs Weasley's dedication to mischief.

Mr Prongs agrees with Mr Wormtail, but believes perhaps the duo need to be slightly more solemn.

Mr Padfoot finds that young Messrs Weasley's are entrancingly troublesome, and solemnly swears he would very much enjoy a pint with the two.

Mr Moony would not endorse a pint, yet does endorse other words used by Messrs Padfoot and Prongs.

Once more, the twins shared a glance, and Fred placed his wand on the paper once more.

"I solemnly swear I am up to no good."

Before their eyes, words once more appeared upon the parchment.

Messrs
Moony, Wormtail, Padfoot and Prongs are proud to present
The Marauders Map.

"What is this," Fred asked, his young eyes widening as George began to unfold the parchment.

The two stared at the parchment, and quickly recognised it to be some form of map, and it somehow was of Hogwarts.

The twins were stunned to see that wasn't even the end of it. As they stared, they could see small dots moving throughout the map.

"George."

"Yes Fred?"

"That's not Percy, is it? See, on the fifth floor corridor."

"Blimey," George exclaimed, "can we see where everyone is, all the time?"

Fred grinned, keen eyes scanning the parchment until they landed on the dot labelled "Argus Filch".

"Brilliant," the two chorused.

"George look, everyone's headed to the great hall, it must be dinner, we better go."

"Fred, this map is going to be the key to our success."

"You know, I think you're right Georgie. Do you think we need to, well, lock it again.

The red haired boys mused for a few moments, before words appeared along the edges of the parchment.

Messrs Moony, Wormtail, Padfoot & Prongs would do well to advise Messrs Weasley and Weasley to manage their mischief so that it does not land the two in trouble.

Grinning, George placed his wand to the parchment a final time, whispering two words as Fred smirked at his brother.

"Mischief Managed."
