Whee! Last prank chapter and then the epilogue, which won't be too long, just a few hundred words. I was amazed at the amount of reviews for the last chapter, which, of course, made me work faster on this! So, I won't bug you with an annoyingly long author's note at the beginning, so off you go! Allons-y! Molto bene! Fantastic! Yup, I'm hyper!

Disclaimer: I have a better chance of winning the state lottery than owning Harry Potter. That said, why haven't I won yet?!

Warning: Before reading this chapter, please pour out all beverages to prevent spillage on computers, swallow all food to prevent choking, and be ready with the tissues. Believe me, you'll be glad you did.

It was safe to say that Snape was not amused by the pranks that were happening to him, but the Valentine's Day prank had really gotten under his skin, though thankfully none of the teachers had. The thought of all those teachers and students, some of the latter male, sent shivers down his spine every time his Occlumency failed him for a moment.

However, it would be the next prank that would start his fall from sanity.

Prank #21

February passed, slipping easily into March. As the one-month anniversary of the last prank came and went, Snape began to relax. Perhaps it was because he figured that the Aphrodisiac Potion was the best the pranksters could do or the long amount of time since then, but either way, Severus Snape let his guard down and failed to follow the most important rule in the spy manual.

Constant Vigilance!

Snape entered his seventh-year NEWT Potions Class (which had four Slytherins, four Ravenclaws, three Hufflepuffs and a Gryffindor), intent on one potion for that day.

"Today we will be brewing Felix Felicis, as today is St. Patrick's Day. Felix Felicis is also known as Liquid Luck. Begin."

Silently, the class broke into pairs and began brewing the potion. When they were done, they turned in their samples and left.

Snape smirked with satisfaction. Nothing so far. Must be his lucky day.

Snape had just finished his lunch in the Great Hall (green eggs and ham, of all the infernal things; better than the pink at least), when he was engulfed in a green smoke. McGonagall, who had the misfortune of sitting next to him at that time, managed to lean back without inhaling any of the smoke.

Which was lucky for her, considering the results.

When the smoke cleared, there was a decidedly shorter Severus Snape, with green robes, auburn hair, pointed ears, and a very dazed expression.

"Ach, t'would be me luck," muttered Snape, his voice also altered to an Irish brogue, "to be turned into a leprechaun."

Flitwick giggled, a rather disturbing sign from the diminutive Charms professor.

"Oh, shut yer trap, ye wee man," muttered Snape, slumping down in his chair.

Prank #22

March slipped easily into April, but Snape did not. The pranks were getting stronger; this time, the prank had taken a week to wear off, during which he had been forced to teach his classes as a leprechaun. As the end of the school year approached, Snape took to counting down the days in his mind. At five weeks, two days to go, the next prank hit. April Fool's Day, as it happened.

As Snape made the trek to the Great Hall from his quarters, he noticed the students sniggering at him, but stopping and wearing innocent expressions whenever he glared at them.

By the time he had reached the teacher's table, all the students except his Slytherins (who had horrified expressions on their faces) were outright laughing.

"What?" he snapped.

"Um, Professor?" said one brave small Slytherin. "You're wearing Gryffindor robes."

Startled, Snape looked down to see that somehow his black set of robes had been switched for a standard seventh-year Gryffindor set of robes.

"And…your hair too, sir."

Growing steadily more furious with each passing second, Snape conjured a mirror from thin air. Indeed, his normally lank, greasy hair had been replaced with a red and gold Mohawk.

Snape counted to ten in his head to keep from exploding right there on the spot. With a wave of his wand, his hair and robes returned to normal. Without even a word of thanks to the Slytherin, he marched to the table and viciously began attacking his breakfast.

Prank #23

It had taken him several months, but he had finally figured out that the pranks done recently were holiday-related. With Easter on the coming Sunday, he braced himself for the worst, but hoped for the best.

Well, you know the phrase, "Hope springs eternal"?

Snape's spring was drying up fast.

Snape attended Easter lunch with the feeling of a man headed for his execution. His wand was at the ready and he checked every corner before he turned, making most students avoid the paranoid Potions Master whenever possible. A few even dared to make the crazy sign behind his back to their classmates.

After checking his chair for curses, potions, or other magical alterations, he gingerly sat down and began eating, but only after McGonagall had eaten her portion without adverse effects.

At the end of the meal, a beautiful Easter egg appeared on all the teachers' plates. Figuring that the prankster wouldn't dare prank all the teachers, especially Dumbledore, he cracked his egg open.

A multi-pastel cloud of smoke engulfed the staff table, dissipating after a minute to reveal five very embarrassed professors.

Each professor now looked like a lifesize rabbit (A/N: Anyone ever since The Santa Clause 2? Yeah, that).

McGonagall was now a huge rabbit with emerald-green fur to reflect the robes she had been wearing. Dumbledore was a huge fluffy white rabbit, complete with his half-moon spectacles. Sprout was an earth-green rabbit with brown splotches. Flitwick was a fluorescent yellow rabbit about his original size.

And, of course, Snape was a black rabbit.

"I'm going to kill whoever's responsible for this," muttered Snape under his breath as he chewed on a carrot.

Prank #24 (My thanks to Kitchila77. Not quite what you suggested, but close)

May dawned bright and clear, promising a brighter future.

Just not for Snape.

As he was about to enter the Great Hall, Snape suddenly felt his body go rigid. His mind, surprisingly, was still clear, but as his body began to move on his own, he could tell he was now under a Marionette Jinx, known for inducing funky body movements, but not controlling the mind. Hence, why it wasn't up there with the Imperius Curse.

However, someone had modified the jinx so that it also controlled his vocal cords. To his horror, he began singing the wizarding version of a pop song, not to mention the body movements. (A/N: How about Prince Charming in Shrek 2?)

"I'm too sexy for my love,
Too sexy for my love
Love's going to leave me.

"I'm too sexy for my robes,
Too sexy for my robes,
So sexy it hurts,
And I'm too sexy for Hogwarts,
Too sexy for Hogwarts,
Beauxbatons and Durmstrang.

"And I'm too sexy for your party,
Too sexy for your party,
No way I'm doing the hippogriff!"

At this point, the Marionette Jinx gave out, to the disappointment of the students that had gathered to watch. One even cried for an encore, a mistake as Snape's reaction was to the student–

"One hundred points from Gryffindor!" he bellowed, his eye twitching so badly it was almost shut. Quite reminiscent of Charles LaRousse Dreyfus when confronted with Inspector Jacques Clouseau, actually, from The Pink Panther movie series.

In the Gryffindor Common Room, two boys and a house-elf began scheming for their grand finale.

And boy would it be a finale worthy of the Marauders.

Prank #25

Snape woke up the last day of school with a feeling of uneasiness in his stomach. This past year had been filled with pranks the like of which hadn't been seen since the end of the Marauders' last year at school. Especially the end-of-year feast.

He sat bolt upright.

Last day of school. Today.

Snape groaned and wondered if he could get out of the end-of-year feast without suspicion. No, it was required that all teachers attended the feast.

He briefly toyed with the idea of defying the Headmaster before rising and continuing on to what felt like his execution.

The students were laughing, eating and drinking, with nothing amiss. Still, Snape kept his eyes and ears pealed for any sign of pranks. Slytherin had won the House Cup with his last minute deduction of points from Gryffindor. He still shuddered when he thought of his singing "I'm Too Sexy."

The main course ended without any trouble and the desserts appeared. Snape watched in disgust as the Gryffindors dug in without any sense of decorum, while his Slytherins ate primly. Snape began eating his own dessert, a nice big helping of chocolate ice cream, which, after this year, he felt he had earned.

About five minutes later, he heard Trelawney shriek. Rolling his eyes, he looked around Hagrid's bulk to see the Divination Professor's desserts rising and beginning to float as if underneath the influence of a Hover Charm.

A gasp from McGonagall alerted him to her desserts rising as well. Matter of fact, all the desserts on the teacher's table were rising and floating.

Then, to everyone's surprise, all the desserts aimed for Snape like bullets. He didn't have time to withdraw his wand and cast a Protego, so each dessert hit him, covering him from head to foot in gooey treacle tart, hot apple pies, jam-filled donuts and sugar-coated chocolate éclairs, squishy multi-colored jello, thick rice pudding, and of course, half-melted blocks of every flavor ice cream possible.

And a strawberry on top.

For what seemed like an eternity, there was silence in the Great Hall. Even Dumbledore stared with a slackened jaw as to the state of the Potions Master.

Then, making everyone in the Hall jump a foot, Snape began to laugh. He howled and snorted so hard that tears were running down his face in rivers, washing away the desserts.

Quickly, Dumbledore cast a spell on Snape that caused the poor man to fall into a temporary sleep. With another wave of his wand, the two men disappeared. A minute later, Dumbledore reappeared, putting what looked like a sock into one of his robe's many pockets. He stood to address the students.

"Someone in this school has been guilty of playing pranks on Professor Snape. I can only hope that the culprits realize that this prank was literally the last straw for him. He will be transferred to St. Mungo's for the summer. Hopefully, by next school year, he will have regained his sanity and will resume his teaching post."

With scattered applause, Dumbledore sat down and the students finished their desserts in silence.

At the Gryffindor table, two red-headed boys gave each other under-the-table high-fives whilst a house-elf in the kitchens at the Gryffindor Table grinned like a maniac.

Well, I did warn you. Anyway, that's the last of the pranks for this story. A little epilogue chapter is on the horizon though, so please don't consider this story finished just yet.

Thanks to the lovely reviewers. Each of you deserve a Triwizard Cup for reviewing, but as I'm a lowly writer, you'll have to do with imaginary ones:

rikkurox, ballerinadoll9, RebeccaRoy, Wotcher-Tonks, Samara Nightshade, Shadowed Ember, phoenixrising93, mrmistoffelees, bella3590, RandomPersonxdurr, jolie7886, GinnyWeasleyLover, Maya Yin and CrazySmallLady.

So, thanks for reading, now please review if you're not in too much pain from laughing. And the epilogue will be up as soon as I finish it.
