Spike (Discord) sees Twilight Sparkle, Rainbow Dash, and Applejack in his classroom, along with several ponies he doesn't recognize. He knows what to do to get under Twilight's skin a bit. Spike (Discord) asks everyone in the class to introduce themselves and to be honest about themselves. Twilight Sparkle, Rainbow Dash, and Applejack had difficulty explaining themselves and why it led to this. The other ponies in the room felt disgusted that Princess Twilight Sparkle and her friends would ever treat their teacher lower than dirt. They are not even sure if they can look at Princess Twilight Sparkle and her friends the same ever again.
"Now, I ask of you, please do not allow hate to consume your minds. It'll mess you up on how to become friends with other creatures in our world," Spike (Discord) explains. He takes a deep breath.
"What will today's class be about, Spike?" A green pegasus named Buddy asks.
"Today will be the first of many that I'll be teaching you what's acceptable in Friendship and what isn't."
Twilight, Rainbow, and Applejack gulp a bit. Their in for an unpleasant surprise in reliving moments of their lives. Everypony else is anxious to know what Spike has in store.
"Disco, you got the bucket?" Spike (Discord) asks.
"Yes, I do," Disco brings in the bucket. He brings all sorts of items that are for pranking.
"Oh no," This causes Rainbow Dash to remember her pranking spree on Spike. She's not looking forward to being reminded of her actions.
"Now, who here enjoys a good prank once in a while?" Spike (Discord) asks. He sees many ponies raising their hooves except for Twilight, Applejack, and Rainbow Dash. "Now, I see somepony who is lying. Telling lies doesn't build character in Friendship."
"I can't! I can't raise my hoof! I don't want other ponies to give me a bad reputation! Why me? What did I do to deserve this punishment!" Rainbow thought to herself.
Spike (Discord) sighs. "Very well, remember that lying to yourself and others isn't healthy in Friendship. Now, going back. A prank is good as long as it's a harmless prank, right?"
Everypony nods their heads except for Twilight, Rainbow, and Applejack.
"What if I tell you that certain pranks can make some creatures become ill or hurt. Will you pull those pranks?"
Everypony shakes their heads. Some are saying that somepony willing to pull those kinds of pranks are merciless and not caring. Rainbow Dash feels ashamed of herself.
"Now, here's a classic bucket of water prank on a door," Disco places the bucket where it's slightly open. He teleports outside. "As you see, the bucket of ice water is placed above the door. Anyone who opens the door without knowing will be drenched with ice water."
Disco opens the door as the bucket filled with ice water hits him on the head. Some ponies laugh a little as Disco falls to the floor with the bucket hitting on his head.
"I see we have some ponies who laugh at other creature's misery," Spike (Discord) seriously says.
Those ponies who laugh stops as they just laughed at someone's misfortune. Disco is slow to get up.
"As you see, getting hit on the head with a bucket is serious. Disco may be a clone of Discord but, what if you've done that to a dragon? Do any of you know what happens when you prank a dragon with ice water? Anyone?" Spike (Discord) looks thoroughly around the room. He anticipates for Twilight, Applejack, or Rainbow Dash to answer. The trio doesn't want to answer. "Rainbow Dash," Spike (Discord) calls out.
"Uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuh," Rainbow prolongs the answer.
"You should know; you saw it happen before."
Rainbow Dash sighs. "Dragons are cold-blooded, so when they get drenched with cold water, they feel extreme pain depending on how much cold water is in the bucket. Also, too much cold water can render them sick or death," Rainbow Dash closes her eyes and looks down in shame.
"That's correct," Spike (Discord) hears everypony else jotting down notes so they don't harm dragons with cold water when they decide to joke around them a little.
Disco plants a whoopie cushion on Spike's (Discord) chair. He sits on the whoopie cushion making a fart sound which causes everyone to laugh.
"As you see, this prank may be old school but, it's harmless," Disco pulls the whoopie cushion. "Harmless pranks are the better pranks. Even some scare pranks."
"Pranks that cause pain is no laughing matter unless you have a cruel-sick mindset for joking around."
"So, besides pranks, what else will you be teaching us?" Rainbow asks.
"Name-calling," Spike (Discord) smiles.
Rainbow gulps. She feels targeted with today's lesson. The other ponies turn to Rainbow Dash and see that she has a problem with name-calling. Twilight raises her hoof.
"Yes, Twilight?" Spike (Discord) answers.
"Why are you teaching topics like these? Why not go over the basics of the Elements of Harmony and how they bring Friendship to everyone?"
"This is my class and how I'll be teaching. Sure the Elements and what they represent are important but would anyone here like to have a racist as a friend?" Everypony shakes their heads as their answer. "I'm teaching everyone here on what to do and what not to do. Say what is good and pleasant, and don't say anything that is hurtful. Are you saying that I shouldn't teach those kinds of lessons?"
Twilight stumbles with her wording. Spike got her good. "Well, uh, it is good to know that everypony.., I mean every creature should say what's right and not disrespect them. Do things that are fun and not harmful. But, the Elements are-" Spike cuts Twilight's speech.
"Not important with my lessons going forward. I have everything planned out. Maybe someday when you decide to be a teacher, you can teach how important the Elements of Harmony are. Until then, do not interrupt my class on what I teach. You'll be wasting my time, your time, and everyone's time here in this class. You are here to learn, not challenge my teaching efforts based on what you think it's appropriate, Twilight."
Twilight pouts and sighs. "I still think it's important that everyone should know about Laughter, Honesty, Loyalty, Kindness, Generosity, and Magic."
"It is but not in this class I'm teaching. Maybe Headmare Glimmer will be teaching that in her class," Spike (Discord) formally said. "Now stop asking about the Elements of Harmony and allow me to go forth with my teachings, Twilight."
"It's blatant!" Rainbow shouts, disrupting the class. "You're targeting us on what we did to you!"
Spike (Discord) glares at Rainbow Dash. The students in the room feel awkward. Spike (Discord) takes a deep breath.
"I'm using my experiences to teach other creatures what not to do towards a friend. I didn't say who cause what to me. This roleplay act I'm doing is to show what can happen to certain creatures who may not like the outcome," Spike (Discord) takes a deep breath. He goes to his desk and writes a form. He walks up to Rainbow Dash and hands it to her.
"What is this?" Rainbow asks.
"Your detention slip. After school, you'll be in detention for one hour for disrupting the class."
Rainbow Dash's jaws drop. She never received detention on the first day until today. She feels targeted even more.
"I didn't want to do that. I didn't want to start giving out detention slips to anyone that interrupts my class. Twilight, this is your last warning. Remind me of the Elements of Harmony in my class again; you'll be going to detention. Now, let me teach before class-" Spike (Discord) hears the bell ringing. "Over."
Everypony hurry out of the classroom, not wanting to stick around to see Twilight, Applejack, and Rainbow Dash having their arguments with Spike. Spike (Discord) balls his claws then relaxes.
"Go to your next class and remember what I'm teaching. I mean no disrespect but, this is what I decided to teach to my students. So no one has to go through what I endured," Spike (Discord) sounds displeased and upset. He watches Twilight, Rainbow Dash, and Applejack leaving.
"This is going to be a long year," Said Applejack as she walks with her friends to their next class.
