A/N: An idea that just popped into my head after reading Deceptions by WolfMoon. Let me know what you think!

Disclaimer: I don't own Harry Potter!

Harry James Potter was lying on one of the couches in Grimmauld Place, The Hobbit open to one of the later chapters in his arms. Kicking his legs upward slightly, he pursed his lips and flipped a page.

The young Gryffindor was rather glad, he decided absently. Glad because his godfather- no, father now- was free of the shackles that had made him a prisoner of Azkaban. Pointedly, the near fourteen year old licked one of his fingers and turned another page of his book.

The emerald-eyed boy jumped slightly when someone knocked at the front door around the corner.

"Ah." Remus Lupin sighed softly across from him. "That ought to be Padfoot coming back from the store."

Harry turned wide, incredulous eyes onto his uncle. "Pads went to the store?!" the boy's voice held a note of increasing shock. "He pretty much swore he wouldn't-"

"No, he went to the new pranking store in Diagon Alley." Remus explained patiently, as the knocking grew even louder and increasing in frequency. A malicious grin spread across Remus's face. "I'm going to do something we haven't done in a LONG time." he snickered softly.

Slipping off of his oh-so-comfortable armchair, the werewolf approached the door with cautious, if silent steps. The wicked gleam of mischief in his eyes made Harry curious though. The thirty-four year old man was acting awfully suspicious though. Almost curiously, Harry watched as Remus slunk up to the door and slid back something Harry knew that wasn't there before.

Revealing a tiny opening, Remus blinked once and asked, "Password?"

In increasing amusement, Harry listened to something that sounded like complaining from his godfa- father. "Aw, just let me in! Please? You don't really need to do that." After a few seconds, Remus shut the piece of wood. Offering a smirk to the left-over Potter, he slammed it back open and asked, "Password?"

Mild cursing could be heard from the other side of the door. Sliding the wood back shut, Remus stage-whispered to Harry, "Each of the Marauders and Order Members has their own password. This became his purely on accident during sixth year."

"Oi! I can hear you!" came Sirius's indignant yell. "Let me in!"

For a few moments, silence rang through the hall. It became almost creepy until, "C'mon Remus, my arms are getting tired."

Remus and Harry exchanged a wide-eyed look.

Then.. "Password?"

Snickering, Harry almost went back to his book. However, his keen ears picked up on the rather loud, reluctant sigh from the other side of the door.

"..Fine."

Knock.

Pause.

Knockity-knock-knock.

Knock-knock-tap.

Pause.

KNOCK.

Pause.

KNOCKITY-KNOCKITY-KNOCK-KNOCK-TAP.

Slight pause, and by now, Harry's face was turning red from the laughter he was so desperately trying to keep in.

Then all of a sudden:

BANGITY BANG BANG

BONG CRASH BANG

"Moooonsiiieee let me iiiiiin!" came a loud, belligerent cry.

BANGITY BANG BANG

BANG BANG BANG

BANGITY BANGITY BANG

BANG BANGITY BANG.

"I know you're iiiiin theeeeerrre!"

At this point, Harry was on the ground and trying not to crack a rib. Not to mention his face was pretty much turning purple from not being able to breathe.

BANG BANG BANG BANG

BANGITY BANGITY BANGITYBANGBANGBA-

CRASH!

Sometime between the loud bangs, Remus had left the door unlocked. Instead of simply opening it, Sirius had made the door fall in with a loud noise.

...Then..

"MOOOOOONYYYYY! WHERE AAAARE YOUUUU?!" Sometime between the loud bangs, Remus had left the door unlocked. Instead of simply opening it, Sirius had made the door fall in with a loud noise.

The resulting prank war lasted for approximately a week before Harry joined in for the rest of the summer.
