Ok, before we start, I wanna say, yes, I know he isn't really allergic to peanut butter, yes I've seen the bloopers were Peabody clearly made him a peanut butter sandwich, this is gonna be an AU where Sherman is allergic though.

Sherman sat down at the lunch table with his friends, Penny, Mason, and Carl. He placed his brown paper bag on the table and opened it, the normal tuna and carrot sticks. He took a bite of his sandwich, Penny snorted at him slightly.

"Tuna again? Is that all you guys have or something?" Penny asked as she took out her own sandwich. Just by the smell of it, Sherman knew what it was, peanut butter. He stuck his tongue out at the smell, the smell of peanut butter always made him feel sick. Maybe it was because peanut butter literally made him sick or because at this point just anything with peanuts were just repulsive to him.

Of course, him and Mr. Peabody found out the hard way about his allergy. According to Mr. Peabody, when he was around one or two, the dog had given him some peanuts to snack on. One minute Sherman was happily eating, the next minute, he was having a horrible asthma attack. After being rushed to the hospital Mr. Peabody found out about Sherman's nut allergy, sense then Sherman had to bring an epipen with him in case of emergencies.

"I happen to like tuna." Sherman said proudly to Penny, who just rolled her eyes at the ginger boy.

"Tuna is very healthy you know" Carl butted in, earning him a glare from the blonde girl, he quickly quieted down and went back to eating his lunch. Penny may of been friends with Sherman, that didn't mean she was friends with his friends. Carl shut up and just ate his lunch.

Sherman rolled his eyes and scrunched his nose a bit as the smell of peanut butter seemed to be getting stronger. Penny noticed the scrunched up nose and rolled her eyes at Sherman.

"What? Don't like the smell of fish?" She laughed at him and Sherman snorted at her.

"The fish is fine, it's your sandwich that's making me nauseous."

"It's peanut butter."

"I know, I don't like peanut butter."

"How can you not like peanut butter?!"

"It makes me sick..." Sherman said rolling his eyes, looking down at his lunch he realized he didn't have anything to drink. "I'm going to get a milk." he said putting his sandwich down. Getting up he walked away, Penny smirked, she quickly placed her sandwich down and swapped it with Sherman's own.

"Uh, Penny, Sherman just said that Peanut butter makes him sick." Carl said, Penny rolled her eyes at the boy.

"Please, how can Peanut butter make someone sick? He's just being a wuss." She told him with a smirk on her face. She couldn't wait to see Sherman's face.

Soon, the ginger boy came back, a white milk in his hand, he sat down and grabbed, what he thought, was his sandwich. He took a bite, Penny waited, trying hard not to laugh.

She got her reaction. But it wasn't the reaction she wanted.

Sherman's breathing became weird, his face turned red, he then started to cough, really bad.

She, Carl, and Mason looked around, they didn't know what to do.

Sherman fell out of his chair and started to hit the ground with his fist, like, he couldn't breath. He let out strangled gasps, trying to get some air into his closed up throat. Tears started to run down his face, he felt like he was on the verge of blacking out.

Penny sat there, shocked, what was going on? what was happening to Sherman!?

She didn't even notice the teacher that had ran up to them, until the said teacher brushed up against her to get Sherman's lunch box.

"W-What are you doing?" She asked, the teacher didn't respond she just ripped open Sherman's lunch box and dumped all the contents on the table. She soon found what she was looking for. A small cylinder thing, she uncapped it and Penny realized it was a needle of some sort, why would Sherman need that?

The teacher ran towards Sherman, whose struggling seemed to slow down and almost halt completely. Penny watched as the teacher stabbed Sherman in the thigh with the needle. With in seconds, Sherman started breathing again, he started to gasp and his chest moved normally again. The teacher helped him up.

"C'mon, lets go and see the nurse." The teacher said soothingly as she lead Sherman away. Penny felt a hand on her shoulder, she looked up, it was the principal, instantly she paled.

"Lets you and me have a little talk, young lady." He told her and hesitantly she got up and followed him to his office. Along the way, they passed the nurse's station, the door was wide open, when they passed, she saw Sherman sitting on one of the bed type things, an inhaler in his mouth, odd, he never needed it before.

When they made it to his office, she sat down across from his desk, before talking to her, however, he picked up the phone and dialed a couple of numbers.

"Yes, Joan? Call Sherman's father, tell him that Sherman is in the infirmary. He should probably come and pick him up. Tell him to drop by my office first." He told the secretary then hung up the phone. He then looked at Penny and with a slightly disappointed voice and look said. "I don't understand, you and Sherman seemed to be getting along so well."

"All I did was swap my sandwich with his! I didn't know he would do that! What happened!? Is he going to die!? OH NO, I KILLED SHERMAN!" She cried, tears now running down her face. Penny buried her face in her hands and started to sob into her hands. Her shoulders shaking with each sob.

"Ms. Peterson, please calm down, here." He handed her his box of tissues, she took one and blew her nose, then wiped her eyes. Once she calmed down enough, the principal sighed again. "You did not kill Sherman, though if he didn't have that epipen on him then it would of been a different story. Ms. Peterson, from what I saw, Sherman has a peanut allergy, it means that he can't eat anything with nuts in them, that includes peanut butter." He told her sternly, he then straightened a bit.

"All he told me was that Peanut butter makes him sick, I-I thought that he just didn't like the taste or something." Penny whimpered slightly, she then blew her nose again.

There was a knock on the door.

"Yes, come in." The principal said, it was Mr. Peabody.

"Ah, yes, Mr. Peabody you came here quiet quickly." The principal said as Mr. Peabody sat in the chair next to Penny.

"Yes, Well, I was already on the road when Mrs. Joan called me, is Sherman alright? What happened?" The dog asked, Penny wiped her eyes again.

"Ms. Peterson, please explain what happened." The principal told her, she nodded.

"We were at lunch, Sherman told me that peanut butter makes him sick, so as a joke, I swapped his and my sandwich, Oh, Mr. Peabody! I'm so sorry! I didn't know it literally made him sick!" She cried in to her tissue and blew her nose. Mr. Peabody looked at the principal. Before the dog could say anything, the principal spoke.

"Yes, he had his epipen on him and yes he's breathing. Why don't you tell Ms. Peterson what happens to Sherman when he eats peanut butter, it does more than 'make him sick' I'm guessing."

"You are right, Ms. Peterson, when Sherman eats anything with peanuts in it, it causes his throat to swell up. Which means that he can't breath, you see, he has to carry an epipen around just for cases like this, the epipen opens his throat up again. Now, I would like to go and see my son now." With that Mr. Peabody hopped off his seat but before he walked out the door, he spoke one more time.

"Oh, Ms. Peterson, in the future, if someone says that something makes them sick, don't feed it too them, it's not funny."

When the door shut, Penny sobbed into her tissue.

"I'm a horrible person." She said in a gaspy breath. The principal sighed, he reached over and placed a hand on her shoulder.

"You are not a horrible person, but, understand this, this cannot go unpunished, you could of hurt Sherman badly if he didn't have that epipen on him. You have a week's detention, now, go back to your class." He told her and she slowly got up and walked out of his officer. On her way to the class, she passed the nurses station again, the door still open, but no Sherman or Mr. Peabody, he must of been taken home.

'I really am a bad person...'
