Chapter 4

Teaher for the Day

The class of freshmen high school students screamed as they threw paper airplanes and spit ball at each other in the old Biology room. The girls sat in the corner by the window, talking about cute boys and the newest fashions. The jockey boys stood around a boy with large glasses and a green flannel. They punched the boy in the gut, sending him to his knees. The class laughed heartily at the nerd as he sputtered on the floor.

"Teacher!" cried a boy with blue dyed hair and a torn up sweat shirt. He smelt of smoke, drugs, and enough alcohol to destroy around thirty kidneys. Everyone dashed from where they stood and skidded to their seats, leaving the nerd on the floor as he slowly picked himself up. Four men walked into the room. One they all knew from spending hour after hour in his office. His balding head was so shiny you could kill ants with it and he wore a way too tight suit. Behind him was a man with salt and pepper hair. He was casually dressed, but his right pocket of his coat was bulging out like there was something heavy there. The shorter man behind him was blondish. He was wearing a jumper and holding an ice pack to his head. A dark purpling bruise was appearing just above his eye and it didn't look like it was going to heal any time soon. He was talking silently to the very tall man behind him. His big dramatic coat was flowing under his feet as he walked. He had dark curly hairs and high cheekbones that made a good number of the girls in class swoon. His eyes were icy, but a smile was painted on his lips as he talked to the shorter man.

"Reggie, what are you doing out of your seat?" the principle asked in a booming voice as he stared down at the nerd of the class. Some of the other students snickered at the nerd as his face paled. The three mysterious men just stared at him. Two looked at him with remorse while the other only stared with no emotion at all. Reggie got up on his feet and hurried to his seat in the very back of the class, somehow managing to get a 'kick me' sign on his back. Once everyone was seated the principle got back to business. "Mrs. Avery is not going to be teaching your class today due to a turn of events. Mr. Lestrade, Dr. Watson, and Mr. Holmes shall be your substitute teachers for the day," he stated. "Any questions?" A snooty girl with blond hair raised her bracelet infested hand. The principle let out long sigh and stated irritated,

"Yes, Penelope?"

"Actually, Principle Stewart, today my name is Susan," the girl stated, sticking her nose up high. Principle Stewart simply glared at her and she carried on with her question. "Are we really that bad that you had to higher three teachers for us?"

"Yeah, Dude, like no need to like double up on us," said a boy with a close shaved head and a huge wad of bubble gum in his mouth.

"Hey, or are these guys like…a couple?" a girl with dark hair, glasses, and a short skirt swooned. Dr. Watson bit down on his lip, frowning viciously, but Mr. Holmes tugged him back. The class simply just screeched in laughter, slapping their hands against the table and shouting insults at the three men.

"ENOUGH!" Mr. Holmes boomed. His voice was deep and cold, sending the students into silence. They stared at him in surprise as he stepped out so now he was in the very center of the large Biology room. Mr. Holmes's eyes swept the room, staring at each and every teenager until they all looked away from his dagger-like eyes. "We are your teachers for the day and you shall treat us with respect if you would like us to treat you with respect. If not…well, you don't want to find that out do you?" A shiver went up the backs of everyone in the room at the last sentence and even the other two teachers looked a bit in shock. Still, everyone remained silent. Principle Stewart smiled at Mr. Holmes, wishing him luck and disappeared through the door.

"So then," Mr. Lestrade began. "Biology." A groan left everyone's mouth in the class as Dr. Watson brought out a thick packet. He passed each one out, giving a glare to any teen who attempted to trip of pin a loser-sign on him. When he came to Reggie's desk in the corner he simply smiled and handed the nerd a packet. Reggie smiled back nervously and watched as Dr. Watson went back up to the front of the class and stood next to his tall friend.

"The lab assignment today is the mixing of different chemical compounds to hypothesize the certain outcomes of the…" The entire class, including the two teachers next to Mr. Holmes lost him after that. There was no telling what he said, so (but mainly to survive) they all just nodded their heads in agreement. "Right!" Mr. Holmes shouted, clapping his hands together and resting them under his chin. "Get started." The student simply just stared at the detective, dumfounded that he actually expected them to do anything. Mr. Holmes's eyes narrowed and his deep voice bounced off the walls.

"NOW!" Everyone bounded up from their seats, grabbing protective glasses and lab coats. They grabbed partners and started their lab, leaving the nerd to work on his own. Mr. Holmes let out a heavy sigh and turned away from the busy students.

"Nice job, Mr. Holmes," Lestrade teased. Sherlock glared at him and slumped down into the desk by the Bio teacher's desk and computer.

"I hate high school…and teenagers," Sherlock grumbled as he quickly typed at the absent teacher's computer.

"I don't blame you," John sighed, watching as the teens rummaged around, creating a mess. "Kids these days have no respect what so ever."

"Hmm…no, I meant I hated how stupid they are," Sherlock clarified.

"Oh, yes, sorry. Of course, I should have guessed," John stated, tossing his hands up into the air in defeat.

"Can you two not argue for two seconds?" Lestrade grumbled, rubbing at his head.

"Well, aren't we happy this morning?" Sherlock teased, clicking at a few files.

"I just want to get out of here," Lestrade grumbled. He wasn't kidding. He wanted done with this. He didn't hate high school. It was the teenagers he was worried about. He liked kids as much as the next person, but teenagers were like a completely different species. It was just a bunch of kids that thought they could rule the world. God knows how many teens he's arrested over these long years and this place was like a gold mine, kids drinking underage and doing all kinds of drugs.

Bang!

They broke from their conversation as a beaker sputtered a dark back vapor. The jock that had beat up Reggie was covered in black soot and his partner Susan, Penelope, or whatever also was.

"Excellent job Ralf and Penelope!" Sherlock shouted, looking up from the computer.

"My name is Susan!" the girl spat.

"Whatever," Sherlock countered, carrying on with his typing. Lestrade looked over his shoulder as he did so. Sherlock was simply glancing over Mrs. Avery's Biology notes and files. Some files were jam-packed with tests and quizzes and others were of labs and class projects. "Found it!" Sherlock shouted triumphantly. He clicked on the file, opening it up to find an acid like foundation recipe. All but Sherlock raised their eyes at the site of the file.

"Sherlock we are not-"

"Yes, we are. We are the teachers today thanks to you, Lestrade, so we might as well play the part," Sherlock mumbled as he stared out into the crowd of students. John frowned at his flat mate.

"Sherlock-" But Sherlock was already on his feet striding out into the circle of desks and consulted the students on their lab experiments.

"I'm guessing that's code for play the dumb teacher act," Lestrade sighed.

"Yep," John agreed, shutting down the computer and striding out with Lestrade to look over the experiments. They all knew something about science so it wasn't completely difficult trying to tell the teens what to do. They still wouldn't have to do this if Lestrade hadn't promised his old friend Diana a Avery to help out with the teaching while she visited family in the hospital. They worked their way down the rows until all three of them stood in front of Reggie's desk. Reggie looked up at them nervously as they stood by his desk, blocking him from the sight of any other students.

"Umm…is something wrong,"

"Not at all, Reggie," Lestrade said calmly. Reggie's nails sunk out of his skin and he managed a small smile.

"I…umm…you-"

"We need an assistant to assist us with a little experiment of ours," Sherlock stated suddenly. Reggie stared at him, his eyes big like puppy eyes. He hesitated, looking down at his hands.

"Don't worry it will only last a little while," John promised the skinny teenager. Reggie stared at the three of them for a moment and then with a small voice he whispered,

"Ok."

Minutes later they were all busy grabbing ingredients and chemicals Sherlock shouted at them as he fiddled with the high technological instruments.

"Excuse me, Dr…Dr. Watson-"

"John pleases," John interrupted. "And this is Sherlock and Lestrade," he added, pointing his thumb at the busy men. Nervously Reggie nodded and glanced around him.

"Why me?" John stared at him, processing the teen's question. With a sigh he patted the teens shoulder and smiled widely at him while saying,

"Because you need help and that's our job as detectives…err…well teachers today I guess." Reggie's eyes widened through his thick glasses.

"Detectives?" he gasped, suddenly looking even more nervous.

"Not today," Lestrade sighed. "Today we are poor sobs who got pulled into helping teach a class of teenagers and smacked by doge balls-"

"Which never would have happened if we didn't decide to take a short cut through the gym, Sherlock!" John hissed at Sherlock while rubbing at the bruise on his head. Sherlock smirked.

"It is hardly my fault that you didn't duck out of the way." John clenched his fists, face turning bright red.

"You-"

"It's all set! Reggie, bring me that beaker filled with green liquid," Sherlock interrupted as he finished setting up the equipment. Reggie, John, and Lestrade huddled around the lab table and plucked at thousands of test tubes and chemicals Sherlock mixed together carefully. Students began stopping what they were doing and watched the four of them work fiercely at the experiment. Reggie and Sherlock however, were the real stars of the show. Lestrade and John simply just handed the two science nerds anything they needed and watched as the chemicals blended together.

"Is that it?" Reggie asked after pouring in a clear chemical. Sherlock looked at the flask bubbling over a heating torch and shook his head.

"We just need on more chemical for it to work, but if we grab the wrong one…well…" Sherlock trailed off. Reggie simply nodded and walked over to the table next to them covered in chemicals, ignoring all the eyes on him as he did so. Hesitantly he reached for one of the two chemicals left on the table and handed it to Sherlock who was smiling widely. "After you," Sherlock stated, handing the chemical back to Reggie and giving him the floor. Reggie stared at him with nervous eyes and glanced at the class that sat all around the room, watching him intently. With a quick nod from his three teachers of the day he poured the liquid into the hot flask. Everyone stared at the flask, waiting for something to happen. Minutes past until finally the liquid in the flask began bubbling and turned a snot green.

"John, doesn't that look like-"

"Oh, my god-"

BANG!

Thick green slime blew up all over the room, splattering against the skeleton by the door and sticking to everyone's hair and clothes.

"Really, again, Sherlock?!" Lestrade grumbled glaring at the slime sticking to his badge. "This is April Fools Day all over again!" Sherlock laughed simply.

"Well, if Reggie picked the other chemical I laid out we could have just had a series of colorful smoke and that isn't as much fun is it, Class?" Sherlock stated, directing his question to the slop covered class, They were all silent, staring at Reggie in utter shock. The nerd backed up a few paces, feeling nervous with so many eyes on him. That's when Ralf stood from his seat.

"That was Awesome!" Reggie's face fell in shock.

"How did you do that? My band could use that for our gigs!" the boy with the blue dyed hair stated, jumping out of his seat and patting Reggie on the shoulder.

"Epically cool, dude!"

"Want to go out, Reggie?"

"Hey, know any more cool experiments?" Reggie was just pelted by his entire class. Ralf apologized for beating him up before and kids smiled and ruffled his choppy hair.

"Nice job, Sherlock," John stated as they watched a smile appear on Reggie's face. Sherlock shrugged casually.

"It was just an experiment."

"JUST AN EXPERIMENT?!" boomed a voice from behind. The three flat mates whirled around to see Principle Stewart beat red with Mrs. Avery at his side looking just as shocked.

"Uh oh…" the three mumbled.

"Dudes, I think it's time to make like a tree and go," Ralf stated.

"It's supposed to be Leave, Ralf," Reggie corrected. Ralf frowned down at the floor, processing this information.

"I don't get it-"

"Doesn't matter the point still stands," Lestrade sighed as Principle Stewart lunged at them. They stepped out of the way of the principle and watched as he slipped onto the goop covering the floor.

"Well, see you later kids!" the three shouted to the kids before darting past Mrs. Avery and into the hall. The teens all laughed, waving goodbye to the best teachers they ever had.

"We need to get out of here before we are the ones with detention," John gasped as they came to a stop in the hallway.

"We could always take a shortcut back to the cab," Sherlock stated, smiling at the gym just ahead of them. The doors were wide open and doge balls were flying left and right. John and Lestrade paled instantly.

"Not again!"
