Pranks with our favorite duo

Sans stepped inside the classroom that he grew to know too well only to find his team-mate there. Yup...Frisk was in detention as well. 

"why are you here..?" Frisk shrugged. 

"This time i didn't actually do anything...but this new teacher keeps being a pain.." Sans raised a bone-brow as he sat down across from her, pulling a chair turning it around and sitting on it with his hands on it's back. 

"new teacher?" Frisk nodded. She put her feet on the desk and blew a bubble and popped it. 

"Yeah, she caught me not in class or something, even if I was just going to class...probably..." Sans rolled his eye-lights. 

"is that why i didn't see you first period?"

"...No...?" Frisk asked smiling. Sans snorted. 

"Why are YOU here though?" Sans smirked. 

"i pranked gerson." Frisk raised an eye-brow and leaned forward taking her feet off the desk. 

"spill the tea, sis. Wha'cha do?" Sans chuckled. 

"taped all his stuff to the desk again. he got so mad he chased me half way through the entire school. ended up getting caught and you know the deal." Frisk rolled her eyes. Suddenly the new teacher entered. Frisk straightened her back immediately. To their surprise, she was human. 

"Well well, i heard a lot about you two." The teacher said, with a fake smile on her face. It was returned by both of them by a bit of bitterness to top it off.  

"Well kids, as you two brats may or may not know i'm Miss Smith." Frisk and Sans looked unphased at her. They returned to their talking and the woman got closer and turned Sans, aggressively, towards the board. Misses Smith shook her head in disapproval. 

"I thought you would know by now you need to face the board...As for you missy...tsk tsk tsk. What a girl you are...Look at yourself. You're just like these monsters...No. You're WORSE!" Frisk looked at the woman in disbelief. 

"Excuse me, what now?" Frisk asked. Sans was looking at the woman as well. 

"Ugh...Can't even wear a skirt for God's sake. What type of girl are you??" Frisk's mouth fell agape as she was listening to the woman. 

"what is this, the 19th century? who are you to tell her how to act?" Sans said in her defense. He ended up getting slapped. The kids eyes widened. 

"You....Bitch..." Frisk mumbled as she was staring at the skeleton in front of her and at the lady who was now arranging her skirt like nothing happened. 

"You've got anything else to say to me..?" Frisk looked the woman dead in the eyes. 

"Touch him again....and i will personally cut you to pieces and dance around the fire i will burn them in...Got it?..." Sans looked at her and smirked a bit. The woman backed away a bit and snarled.  

"Brats. Not to mention brutes...Now then. No talking. I want to only hear silence. I will be out in the hallway. I can hear you two..." The woman stepped in the hallway and Frisk didn't even wait as she cupped the skeleton's cheek-bone. 

"Did she hurt you badly?" He chuckled. 

"i'm fine...but DAMN that threat was something right there. good job baby bones." Frisk puffed her chest up. 

"I know~ Man she makes me angry...What teacher hits their students..." 

"take her out?"

"100%..." They both looked at the door at the woman. Sans rubbed his cheekbone a bit. 

"man it stings." Frisk smiled and leaned over the desk, kissing his cheekbone. 

"Don't worry we're getting rid of her." 


Sans was already in detention as the teacher caught him outside of Gaster's class, waiting for Frisk. Gaster didn't really mind them leaving since 1. they already knew what he was teaching 2.they lived with him and helped him around his lab...Let's be honest that's enough to get them to pass that class. However...He was caught by this Miss Smith. He was however wondering where Frisk was. 

"OI OI OI!! I GOT IT BUT DON'T PUSH ME!! SHEESH..." Frisk said rubbing her shoulder as she got shoved inside the classroom and she rolled her eyes. Sans raised a bone-brow. Misses Smith came soon after her. 

"POSTURE, CHILD!!" Frisk straightened her back and rolled her eyes at Sans. They both had learned sign language so it was easy for them to talk without actually talking...and to sometimes understand Gaster. He loved to talk in sign language when he had ideas or stuff like that for whatever reason...Actually no, he was just paranoid someone will hear him.  

'what happened?'  He signed. She quickly signed her response.

'she caught me at the gate talking with Flowey. She got mad over 1.the fact i was late; 2. my clothes; 3.i had a 'pet' with me.' Sans snorted. The teacher looked at them. 

"What are you laughing at? Trouble is fun for you huh? Imbecile. Bet you don't even know what 2+2 is." Sans rolled his eyes. 

"yeah yeah whatever you say..." The woman got mad at his response and got up, slamming her hands in his desk. He immediately leaned back, sockets going blank. He didn't expect that one...Were all human teachers this aggressive..?

"You have a big mouth for someone your size." Frisk snarled and almost growled. Sans however didn't back down so easily.

"you do as well for someone with the brain size from back in the 19th century. does frisk also need to wear a corsette or something?" Sans said raising a bone-brow amused and looking at the teacher. They both usually were pretty respectful and would only do peaceful and mostly harmless ,apart from a few stains, type of pranks...These people were teachers after all, but they were accustomed to them. They weren't THAT annoyed by their pranks. Gaster even praised them in some. But this lady? oh ho ho...she was truly testing their patience. And Frisk's was clearly running thin. 

"Oh aren't you comic...?" Sans shrugged. 

"they call me comic sans for a reason--" Slap. Ohhh she done goofed. If he had hair he would be sure it would sit up as Frisk's aura was turning quite dangerous. 

"oh shi--" Frisk didn't even wait as she grabbed the woman's hand and twisted it behind her back. The woman was caught off guard and was now sweating bullets. 

"I said. Not. To. Touch. Him. Didn't. I?" Frisk said, her eyes glowing with a reddish hue. The woman immediately yanked her arm and went to the door. She turned around to say one last thing. 

"I-I AM CALLING THE PRINCIPAL!! YOU DEMON!!" Frisk snarled at the woman and stomped her foot. The woman ran out of the classroom. Frisk then went over to Sans and checked his cheek-bone. 

"It's all red...That bitch..."Frisk said. Sans started laughing as he pulled her in a hug. She was now sitting on his knees and he was hugging her. 

"you did great, baby-bones...don't worry about it." He said kissing her forehead. Frisk giggled. 

"Fine fine..."

"do i get a kiss too?" Sans asked. Frisk rolled her eyes. 

"You're pushing your luck here mister..." He chuckled but she turned around and kissed him right on the teeth. That's when they bot heard footsteps. Frisk with one swift move grabbed the desk behind her and jumped over it onto her seat. They both opened their notebooks and started reading. They pretended they were studying together. 

"THESE TWO THEY-THEY-- AND SHE THREATENED....me...." The woman froze as she saw both of them looking confused at her. They both raised a brow and tilted their heads. 

"They look to be doing nothing ma'am..." Gerson said raising a brow at the woman. 

"B-but she just...s-she grabbed me after..." Gerson looked at her. 

"After what?" The woman gulped. 

"Nothing, sir..." Gerson turned around and left. Both of the kids gave her a mischievous smirk and flipped the bird. The woman backed away in shock and left as well. They high-fived each other. 

"I want her gone by the end of the week..." Frisk said smiling. 

"your wish, my command mi'lady." He said returning the smile with a smirk. That woman was in for a ride. 


"THESE TWO HAVE BEEN NOTHING BUT TROUBLE!! THE WHOLE WEEK!! I JUST FOUND A DAMN FROG IN MY FOOD!! THIS IS UNACCEPTABLE!!" The principal sighed. 

"Listen...you must have done something to anger them...There is no other explanation. It will pass with time." Frisk scoffed as she passed the principal's office. 'Over my dead body' she thought bitterly as she started walking towards the cafeteria. 

"Thank you for your time." The door opened and the woman's eyes fell on her. Frisk froze. The door closed behind the woman and she lounged at Frisk. She grabbed Frisk's hair and started pulling. 

"OW! OW! OW! OW!!" Frisk said as the woman was pulling Frisk after her by her hair like some toy or a wild animal. She didn't even do anything yet. Sans was just passing by to get to the cafeteria with her friends. They all stopped and were left speechless. 

"OW OW OW!! LET GO OF ME!! OWWWW!!" Frisk said as the woman yanked her further. Sans sockets went blank as he teleported in front of the woman. 

"let. her. go." Sans said angrily. It was one to hurt him...but it was something else to hurt her. 

"Move out the way kid--"

"i will repeat myself because i'm nice....let.her.go. or else..."The woman reluctantly let go of Frisk who immediately scrambled on her feet. Toriel opened her arms and Frisk immediately went into the goat monster's hug. Sans growled at the woman one more time before going to check on Frisk. The woman looked at the two troublemakers.

"I will get you...Don't you worry about it." Frisk was rubbing her head. The woman left, her heels making loud clacking noises on the ground. 

"are you ok?! man that bitch is stepping out of line alright..."Sans said, stealing her from Toriel, hugging her and rubbing her head. Frisk nodded. 

"How long has she been dragging you by your hair..?" Undyne asked frowning. 

"Two halls...."

"WHAT THE HELL IS WRONG WITH THAT WOMAN?!" Gorgette said. They all agreed. 

She needed to be gone. 


"GET ME DOWN FROM HERE THIS INSTANT!! WHAT ARE YOU DOING?!" The woman yelled as Sans was hanging her by the flag outside of school. As she got hanged Frisk started playing Rasputin really loudly on her bluetooth speaker. She started doing the Russian dance and was laughing alongside Sans as the woman was yelling at them to get her down. People started noticing. Soon enough students started gathering around. 

"SOMEONE HELP!! THEY'RE HEARTLESS!!"

"Ra-Ra-Rasputin! Lover of the Russian Queen!!" Frisk said not listening any slight bit to the hysterical woman hanging by her clothes. 

"yeahhh...should have thought twice before slapping me twice, getting us in detention every day and dragging frisk by her hair two whole halls, bitch." Sans said smirking. The woman screamed louder. 

"Misses Smith did what now?!" Gaster asked as he came from the crowd. Frisk was still dancing. 

"HEY HEY HEY HEY HEY!!" She was saying just as the song got to that part. She smiled, knowing karma was coming for her. 

"That girl is a demon! She's corrupted that boy and has no sense of feminism!! She deserves to rot or die in a hole!!" Frisk froze. Sans sockets went blank and the teachers in the crowd gasped. 

"Die...? In a hole...?" Frisk asked looking at the ground. She smiled and looked up at the woman. 

"Oh miss...don't you get it...? I already tried and failed." She said with a shrug and the woman froze. She wanted to form words but she couldn't. What even was there left to say when a child admits they've tried to suicide before...? Sans growled at the woman. 

"look what you did!! put me and frisk in detention all you want, but you can't tell me she didn't have it coming!!" Frisk shrugged.

"She did." The teachers looked up at the now, again, screaming woman. Gaster smirked. 

"She did have it coming, didn't she...? Hehehehe...i'm not taking her down. Have fun, old man." He said patting Gerson's back. Misses Doods smiled and giggled. 

"She did steal my food and said I have 'no fashion sense'.....Who's the one looking like a flag now?" Frisk patted Misses Doods back. 

"I love your style, Miss." She smiled. 

"Thank you...Now then...that song you were playing?" Frisk beamed and looked at Sans he snorted. 

"RASPUTINNNN!!" She said, replaying the song as she started dancing again. 

"ok ok ok...teach me the dance." Sans said coming next to her. And soon enough they both were doing the russian dance. More and more students joined until the whole school was dancing and laughing at the teacher's missery. Sooo...i think it's obvious she left the school...also i think it's obvious these two got detention for a whole month for that. I mean...they did hang a living breathing person on a flag pole. So, now these two are sitting in the detention room. 

"worth it?"

"So worth it..." Sans snorted. 

"she won't ever pull your hair again." He said as he ran his phalanges through her hair and stopped. 

"holy shit that's soft. what the..?" Frisk started laughing. 

"He's been playing with my hair for months and only now he notices. THANK YOU??" She asked amused. He shook his head. 

"i mean...i knew it was soft but..i never noticed it??" Frisk started laughing. Sans blushed. 

"shut up." She just started laughing harder and he joined in. That day, they talked about hair in detention, instead of doing their biology homework. Why? Because they could.
