Hey guys! :) Thank you so much for all the reviews and everything! Um, I have some really bad writer's block, which is why I haven't updated All Those Lines yet, so I'm really sorry to whoever is reading that. Plus, I just started high school and I have volleyball, so I don't get home until around 7 at night. Then I have homework. Haha, okay, anywho..

I got this idea from my older cousin doing it to my younger cousin, and it was adorable so I'm writing it :) Kendall's 12 and Katie's 6.

I don't own anything.

Kendall, Carlos, Logan, and James sat on the couch in the Knight's living room, flipping through channels on the TV, bored out of their minds. They weren't allowed to leave the house because Mrs. Knight was making them watch Katie, who was up in her room, while she was at the store. They wouldn't have minded, but there was nothing to do in the house, except playing video games, which, believe it or not, was starting to bore them.

"When's your Mom coming home?" James asked, not bothering to take his eyes off the television.

"I don't know," Kendall sighed. "Sorry, guys. You can leave if you want," he offered.

"No, it's okay, we don't mind," Logan assured him. "And besides, we told your Mom we would all watch Katie."

Kendall nodded. "Well, I'm sorry we got stuck doing it... I thought my Mom would be back sooner."

"Really, Kendall, it's fine," Carlos promised. Kendall smiled in thanks before they all turned their attention back to the TV.


The blonde sighed, rolling his eyes, and looked over to see his little sister running down the steps and into the living room. "What, Katie?" he asked.

"I have to show you my new trick!" she exclaimed. The four boys turned around on the couch to watch her as she got down on her hands and knees, stuck one foot up in the air, and began to crawl. They exchanged confused glances, laughing at the little girl, until suddenly, she fell and hit her head on the ground. Katie whimpered quietly and put her hands on her head.

"You okay?" Kendall asked, walking over to her.

"I think I got a booboo..." she said softly. Kendall sat down beside her and looked at her. He saw that there were some tears in her eyes, so he knew he had to make her laugh.

"Do you have a concussion?" he asked, pretending to panic.


"SHE'S CONCUSSED!" Kendall shouted. "Come on, guys, we have to cure her concussion!"

The other three boys laughed and sat down beside Kendall and Katie. He laid her down on the ground and began to hover his hand over her, making 'beeping' noises. "Beep, beep, beep, beep, BEEP, BEEP, BEEP!" he shouted, stopping right over her head. Katie's eyes were wide, a big smile stretched across her face as she waited for her brother to continue.

"JIB JAB!" Kendall shouted, tickling her stomach. "JIB JAB, JIB JAB, JIB JAB!"

Katie giggled uncontrollably, clutching her belly as she tried to get Kendall to stop. "No! Please!" she begged. "I'm all better! I promise, I'm better!"

Kendall stopped and gave her a stern look. "I don't think you're better yet," he said. "Should we check?"

Katie shook her head frantically, still laughing a bit. "No, no, I'm better! No concussion!" she assured him.

Kendall frowned and turned to look at his friends. "What do you guys think? Do you think she's better yet?" he asked, smirking. He could still hear Katie giggling beside him, and he smiled when the three others shook their heads.

"You better not take the risk!" Carlos said.

"No, no, no!" Katie yelled. "No, please!

"Beep, beep, beep, beep, beep..." Kendall stopped. "Maybe she really is better," he said. "Beep, beep, BEEP, BEEP, BEEP! Nope, I was wrong!" He laughed as he started to tickle Katie again. "JIB JAB, JIB JAB!" Kendall watched as his little sister erupted into giggles, curling up in a ball on the ground. "JIB JAB, JIB JAB, JIB JAB!" he shouted, continuing to tickle her.

"P-p-please! I-I'm better, K-Kendall, I-I-I promise!" she cried, tears coming to her eyes from laughing.

"Well, alright, I guess your concussion is gone," he said, smiling. Katie sighed in relief, but as she started to get up, she hit her knee on the floor. "OH NO!" Kendall screamed. He forced her back onto the ground. "Now you have a kneecussion, don't you?" he asked, eyes wide. She shook her head quickly. "Well, we better check, Katie, just to be sure..." he said.


"Beep, beep, beep, beep, BEEPBEEPBEEPBEEPBEEP! UH-OH, IT'S BAD!" he cried. He grabbed her ankles and picked up her legs, lifting them up into the air.

"KENDALL, NO!" she begged, laughing.

"BAM, BAM, BAM, BAM, BAM!" He shouted, gently spanking her butt. Katie squealed as she began to laugh yet again. Kendall put her legs back down, chuckling. Katie, after calming down a bit, sat up and smacked Kendall's arm, but still smiled at him. She sat down in his lap and hugged him, catching her breath as she finally stopped laughing.

"You're a poopface!" she shouted. Kendall held up his hands in defense.

"Hey, I was just saving you from having a concussion!"

"Now you have a concussion!" Katie said as she forced Kendall to lay on the ground. "JIB JAB, JIB JAB!" she screamed, attempting to tickle him. However, Kendall wasn't as ticklish. Katie rolled her eyes. "You're boring!" she whined. Kendall laughed and pulled Katie into a hug again.

"It's just more fun torturing you!" he exclaimed.

This probably won't make as much sense to you guys as it did to me, because my family is kinda crazy, haha. Or maybe it will, I don't know..And I don't know why my cousin was shouting "jib jab", so just...yeah. :) I hope you all liked it! Review?
