"Do we have the itching powder?" asked Sirius as the four walked to Potions.
"Check," answered James, "Do you remember the spell?"
"Check," replied Sirius.
"Do you two know what ingredient to add?" asked Remus.
"Of course we do!" exclaimed Sirius in a slightly hurt manner, "Read the lesson last night."
"Whoa, wait a minute mister 'never-opened-a-book-in-his-life' actually read the lesson?"
"I open books," protested Sirius, "When it suits me and it suited me last night."
"Well, I'm impressed," smiled Remus.
"Here goes nothing," sighed James once they reached the door.
"Wish us luck," grinned Sirius raising his eyebrows getting that mischievous glint in his eyes.
"Good luck," squeaked Peter.
"Sirius and James took their seats with Snape as usual.
"Good Afternoon Severus, we're looking particularly slimy this afternoon," grinned Sirius.
"I don't know what it is you're up too Black but you can just forget it, I'm not falling for one of your tricks today."
"What ever do you mean?" asked Sirius feigning innocence, "How do you like that James? I try and have a somewhat civil conversation with the guy and he bites my head off."
"Well, I guess it proves theories correct," shrugged James.
"What theories?" asked Sirius.
"That not taking showers for an extended amount of time can leave one in a sour mood."
"And it leaves a sour odor too," remarked Sirius waving air away form himself.
"Ha, ha," fake laughed Snape.
"Good morning class," greeted Professor Slughorn, "Let us go over a few precautionary measures you will need to know for this lesson and then we will get right to work!"
It didn't take too long for Professor Slughorn to go over the precautionary measures. Soon all the students were busy at work. James and Sirius kept their eyes on the potion Snape was working on, they were determined to do things right. It wasn't long before Sirius winked at James for the signal. Sirius purposely let an ingredient slip out of his hand and fall into Snape's cauldron.
"Whoops, sorry Sev," shrugged Sirius.
"You buffoon!" hissed Snape turning all his attention to Sirius,"You've just set me back by at least thirty minutes of work!"
While Snape's back was turned to James he dumped the itching powder down his collar. Snape immediately started to itch, at first slightly at the collar next at his back, then all over.
"Potter what have you done?" demanded Snape turning to James.
"Nothing," lied James giving a look of innocence.
Sirius then took the opportunity to add a few more ingredients to Snape's couldron.
"I know you've done something," insisted Snape with a sneer, booth hands scratching away, one at his neck the other at his side.
"I…" started James when Sirius interrupted.
"Hit the deck!" yelled Sirius as a big yellow gaseous bubble began to form in Snape's cauldron. Sirius and James were able to duck in time but it was too late for Snape.
"Potter!" growled Snape through clenched teeth; yellow goop was dripping from his greasy black hair.
"Oh my, what happened here?" asked Professor Slughorn.
"The potion exploded professor," explained Sirius.
"Mr. Snape, I am disappointed, it's your first all year. From the look of it you added you ingredients too quickly and allowed a foreign agent into your potion I'm, afraid I'm going to have to give you an incomplete. Feel free to see me after class to set up a time to redo the potion, in the mean time I recommend you clean your mess up."
"We'll help you clean," volunteered James before Snape could get in a word of protest.
"Totersi," said Sirius pointing his wand at Snape.
Instantly little scrub brushes appeared and went to work on Snape, producing little bubbles while they worked. Snape tried to fight off the brushes by swatting at them but it was all to no avail. The brushes proceeded to rigorously scrub Snape. At one point Snape opened his mouth to protest but a brush quickly entered his mouth and proceeded to brush his teeth. Snape spit the brush out and returned to fighting the brushes.
"I think that is quite enough," interjected Professor Sluhorn realizing what was going on after answering a student's question.
Siruis reluctantly gave a wave of his wand and canceled the spell causing all the little brushes and their soap bubbles to disappear.
"What a shame," remarked Sirius.
"What?" asked James looking up from his potion.
"A perfectly good spell wasted."
"What do you mean?"
"Well look," Sirius gestured toward Snape, "The slime is still there I had hoped he would have come out squeaky clean."
"Didn't you know grease that is set in never comes out?"
"Potter I am going to jinx toy so bad you'll wish you'd never been born," threatened Snape pulling out his wand.
"Not while Professor Slughorn is watching," countered James adding the last ingredients to his potion.
"Class, if you are finished with your potion, leave it here at a simmer, and then you are dismissed."
"That's out cure to leave Sevy-poo," grinned Sirius, "Enjoy your extra class time with Slughorn."
"I'll get you for this," vowed Snape as Sirius and James left with Remus and Peter right behind them.
"I say that was a pretty successful prank," smiled Sirius.
"Mischief managed,' as Moony always, says," grinned James.
"Aren't you two worried about Snape getting you back?" squeaked Peter.
"What? Us? Worried? Don't make me laugh!" exclaimed Sirius.
