Ask AI: Write a story about Bart Simpson wearing a diaper that was just filled with poop from Maggie Simpson.

It was an ordinary Saturday afternoon in the Simpson household—ordinary for the Simpsons, that is, which meant something was bound to go hilariously wrong. Marge and Homer were busy tidying up the house, trying their best to make it look presentable for their upcoming dinner party with the Flanders family. Lisa had her nose buried in a book, diligently completing her homework. In the meantime, ten-year-old Bart was up to his usual mischief. He'd convinced Maggie, his baby sister, to join him in the living room for some fun. Maggie’s angelic face and pacifier in her mouth gave little indication of the chaos that was about to ensue. "Bart, this is a bad idea," Lisa called from her cozy corner of the living room, sensing trouble. "Relax, Lis’," Bart responded, his signature grin spreading across his face. "It’s just a little fun." He turned to Maggie and did his best to put her at ease. "Okay, Maggie, let's play a game." Maggie blinked her big eyes innocently and watched as Bart reached into the laundry basket. He pulled out one of her spare diapers and held it up like a trophy. "We're going to play dress-up," Bart explained, his eyes twinkling with mischief. Maggie gurgled appreciatively, though she clearly didn’t understand. That minor detail didn’t slow Bart down one bit; he proceeded to try and fit the tiny diaper around his own waist. "See? Easy," Bart said confidently, though the diaper’s edges barely reached around his skinny form. "Now I’m just like you, Maggie!" Suddenly, there was a telltale gurgle from Maggie’s direction. Bart barely had time to react before he felt a warm squish against his skin. His eyes widened in horror as he realized what had just happened—Maggie had used his borrowed diaper, and she had definitely filled it up. "Aw, gross! Ew, ew, ewww!" Bart yelled, his usual bravado melting into frantic disgust. Hearing Bart's commotion, Marge dashed into the room, followed closely by Homer. Marge took one look at Bart in the soiled diaper and couldn’t suppress a sympathetic yet amused sigh. "Bart Simpson!" she exclaimed in that well-practiced, motherly tone of exasperation. "What on Earth possessed you to wear Maggie's diaper? You know better than this!" Homer couldn’t stop himself from laughing. "D'oh! Bart, did you forget which end goes where?" he chuckled. Even Marge had to stifle a giggle at her husband's quip. Lisa simply shook her head. "I tried to warn you. Honestly, Bart, do you ever think these things through?" Feeling thoroughly humiliated, Bart peeled off the diaper and handed it to Marge, who expertly whisked it away with more patience than he deserved. "Let this be a lesson, Bart," Marge said with a gentle smile. "Sometimes, a little fun isn't worth the messy consequences." As Bart headed to the bathroom to clean up, he muttered to himself, "No more dress-up games...ever." He knew he'd be hearing about this for a long time, especially from his friends at school once Lisa inevitably spilled the beans. But, in the grand scheme of things, Bart’s Saturday was just another chapter in the wild, hilarious adventures of the Simpson family. And although Bart would never admit it, he wouldn’t trade his family's craziness for anything in the world.
