Characters:

Hermione Granger (know it all)

Severus Snape: (witty snarky Bastard)

Location: Potion Classroom

Normally Hermione would be the first out of her class so that she wouldn't be late for her next class. Today, Hermione was still sitting in her potions class even though it ended ten minutes ago. To say she was not happy was a huge understatement. She had just received the lowest marks in her life in school...ever. She got 80% on her latest potions essay. Hermione was fuming because she had spent hours upon hours on this essay, researching from every other textbook in the library. She had even owled another Potion master. How dare Snape give her 80%. Yes, it was still a high mark but it wasn't good enough for her. Hermione Granger was the know-it-all of Hogwarts.

Professor Snape walked up behind Hermione "Miss Granger, What are you still doing in class? Do you enjoy my company that much you wish to stay back and incur my wrath?" Snape said, smirking at her. "Nnno pprofessor, I mean I...I don't disslike it here, I mean I don't want your wrath," Hermione stuttered. She may have been still fuming over that appalling grade but Snape still scared her. "Well then, what do you want? And make it quick" Snape snapped at her. "Well sir," Hermione said more confidently "I was wondering why I got such a low grade on my essay" She held up her parchment pointedly. "Miss Granger, only you would say think 80% is low grade, being our resident know-it-all. For you information, you didn't receive full marks because I specifically asked you to write what you thought about the Excessum potion not what others thought about it. Isn't that easy enough for you to comprehend? Now scram" Snape said offhandedly, already distracted by a parchment on his desk. Hermione gaped. "Well...I..." Snape looked up and raised his eyebrow "Yes sir" she replied forcefully, changing her mind. She turned out and stalked out of the his office.

Hermione was not impressed. Snape's reason may have been valid but he didn't even notice the amount of effort she put into that essay. Fine then, it was officially pay back time. Hermione admired Professor Snape even though he was a cruel bastard most of the time. However, all that admiration didn't matter anymore. Professor Snape was in some serious trouble now. As she formed many ideas of the pranks she would pull on him, she decided even though she would still keep her work up to date, she would slowly start to let her hair down a little. Her main goal now was to make Snape pay.

She pondered on what her first prank should be. Should she start of big or small? Then it hit her. It was most probably the most ludicrous prank in the world but she was sure the class would get a huge kick out of it.

The next Potions class:

Hermione had snuck in early to class to set up her prank. Now all she had to do was sir back and wait for the fun and for the fun to commence.

"Inside" growled Snape. The class walked in and Hermione took her usually place next to Harry and Ron. "The Potion is on the board. Now get to work" Snape snapped. He walked around the class, checking their progress, taking points off Gryffindor and awarding points to Slytherin. After he was sure no one was going to themselves up he made his way back to his desk to grade some essays. "I suppose I'm lucky Longbottom isn't here anymore" he thought as he set about sitting down. Hermione immediately looked up and watched just as he was about to sit. And then it happened. The biggest, loudest fart heard ever in the history of Hogwarts. The whole class burst out laughing. Furiously, Snape immediately stood up and cast a revealing spell on his seat. There it was, a deflated pink whoopee cushion. The whole class was in hysterics. Smiling gleefully, Hermione tried hard not to laugh.

Snape boomed "WHICH IDIOT MORON PUT THIS ON MY CHAIR?! YOU HAD BETTER OWN UP NOW OR ELSE I WILL GET THE TRUTH SERUM AND HEX YOU TO FRIDAY!" The whole class immediately stopped laughing and looked around, wondering who was brave enough to face the wrath of Severus Snape. Hermione figured she might as well put her hand up so that the whole school would know that it was she who pulled the prank so she slowly raised her hand. The whole class gasped and started whispering. Great Merlin, Hermione?! Red-faced, Snape pointed at Hermione "You! My office NOW. The rest of you, shut up and get back to work" Hermione tried to hide her mischievous smile as she held her head high and marched to Snape's private office.

Surprisingly, Snape's office didn't look a bit like a prison cell. It looked like more of an overstuffed library. Hermione just sat there in awe looking at the books she would like to get her hands on as Snape yelled at her incoherently about her unfit behaviour. Hermione stifled a grin as she started to plan her next prank. Yes, she was getting to like this new wild side of herself.
