Mischief Not So Managed

Snivellus

James and Sirius were peeking from behind the pillar whilst Remus and Peter lurked behind them.
Peeves the poltergeist was giggling uncontrollably as he held an icy bucket of water, hovering over the Slytherin common room entrance. They had been waiting for what seemed a decade when they heard voices behind the door. James and Sirius held their wands at the ready to scourgify Snape.
The door was opening now... The four's heart was pounding against their ribcage and they all felt a rush of adrenaline. It was happening.
As soon as Snape stepped out... SPLASH!
Peeves had tipped the bucket over his head and James and Sirius shouted, "SCOURGIFY!" They watched in amusement as Snape was covered by a mountain of soapy bubbles and his screams echoed the dungeons. That was their queue to run.
James, Sirius, Remus and Peter darted across the place and straight to their own common room.
They clutched their sides as they laughed madly. Tears rolled down their cheeks as they recalled Snape's 'manly' screams.
Sirius and James were still rolling on the carpeted floors as Remus and Peter slowly collected themselves and stood up.
"THAT WAS BRILLIANT JAMES AND SIRIUS!" shouted Peter.
The boys wiped their face and stood up, still letting out a snort every now and then.
Seeing Remus seemed a tad uncomfortable James asked, "Alright there Lupin?"
Remus nodded. "I hope he gets the prank, that's all."
"His skull's thicker than dragon skin, I highly doubt the possibility of that," said Sirius.
Remus frowned.
"Don't worry it's all good fun," said James. This seemed to relax Remus a bit. He nodded.
"Goodness, I'm tired from laughing," said Sirius.
"I'm kind of hungry too," said James. Peter nodded vigorously.
"I think I've got some chocolate," said Remus as he shuffled through his bag. Surely enough he extracted a nice big bar of chocolate which they all happily munched on.

Their bliss was soon interrupted. The door to their common room burst open.
"YOU! YOU SELFISH, HORRID, SPITEFUL BOYS! HOW COULD YOU DO THAT TO SEVERUS? WHAT'S HE DONE TO YOU?"
Everyone was taken aback at this sudden outburst from the quiet Lily Evans. Sirius and James gaped at her as Peter tried to shrink back behind them while Remus shifted nervously staring down at his feet.
"WELL?"
"I-It was just a joke Evans, calm down," said Sirius in a slightly irritated manner.
"A JOKE? SEVERUS IS SHIVERING LIKE MAD AT THE HOSPITAL WING! HE'S PROBABLY CAUGHT A NASTY COLD THANKS TO YOU!" screamed Lily now panting.
"He's got snot to pair with the grease in his hair now," said Sirius cheekily as James and Remus put a hand on his shoulder to stop him from saying anything further.
"You are the most horrible people I've ever met," said Lily lowly, this was much scarier than when she had been screaming few moments ago.
She stormed out of the common room leaving the four boys thunderstruck.
"Blimey that one can scream," said Sirius pretending as though he was getting water out of his ears.
"Sirius do you think we crossed the line a bit?" asked James nervously.
"OF COURSE WE DID!" said Remus before Sirius could answer.
He seemed to be cursing at himself for playing along with the other three.
"Calm down people it'll be alright," said Sirius.
Peter looked as if he could cry which disgusted James greatly, "Don't whine Peter, it's revolting."
Peter looked very offended and upset at this comment and sat up straight quickly.
"I'm going to find Lily and apologize... are you coming?" said Remus as he looked between the three. Peter gulped and nodded. James after a moment of hesitation agreed as well. Sirius had wanted to be stubborn but seeing that James too had agreed he said "Whatever," as he dragged himself along behind them.
