"Hey Pinkie Pie," said Rainbow Dash one day. "Let's have a farting contest!"
"Sounds like fun!" said Pinkie Pie.
Rainbow Dash and Pinkie Pie both thought it was fun to fart, and they found farts to be really funny. They would often fart in front of each other when no one else was around. They wouldn't usually fart in front of anyone else, because they knew not all ponies found it funny, especially Rarity.
They ate a big meal of beans with fart powder sprinkled on them, and within minutes, felt like they were about to explode.
"Me first!" said Pinkie Pie, and she let out a high-pitched fart that lasted five seconds.
PPPPFFFFFFT!
"Not bad," said Rainbow Dash. "But I can do better!"
PPPPFFFFFRRRRRRT!
Rainbow Dash farted for eight seconds. Pinkie Pie giggled, then let out a loud wet fart for nine seconds. Rainbow Dash raised her butt in the air.
BBBRRRRAAAAAAAAAP!
Rainbow Dash farted deeper-pitched for twelve seconds. Pinkie Pie started laughing some more, accidentally letting a loud fart that only lasted one second.
"My turn again," said Rainbow Dash.
"Come on Dashie, that one didn't count!" said Pinkie Pie, and she turned around so her butt was facing Rainbow Dash and farted loud for eleven seconds.
PFFFFFFFFFFFFFT!
"I'm still winning," said Rainbow Dash, but she couldn't help but laugh. Once she was done, Rainbow Dash let out a loud fart for fifteen seconds.
Pinkie Pie fell on her back and laughed so hard she farted for six seconds.
"My turn again," said Rainbow Dash. Pinkie was too busy laughing to listen.
Or to notice Applejack sneaking up behind Rainbow Dash.
Applejack quietly tiptoed behind the pegasus, fixing her eyes on her rainbow-colored tail. Applejack opened her mouth to grab Rainbow's tail in her mouth...
PPPPPTTTTTHHHHBBBBBRRRRRRRPPPPT!
Rainbow Dash let out the loudest, most boisterous fart yet, which lasted seventeen seconds. Applejack fell on her side, and in a flash of green light, transformed into Queen Chrysalis, who had been trying to capture Rainbow Dash so she couldn't interfere with her latest plan.
Pinkie Pie laughed even harder, then got back to her feet and noticed Chrysalis for the first time. "Check it out Dashie! Your latest fart defeated Queen Chrysalis!"
Rainbow Dash turned around to see Chrysalis behind her, gasping for air.
"Ugh, you are absolutely nauseating," said Chrysalis.
Pinkie Pie sat on Chrysalis's face, making sure to avoid her horn, and farted on her for thirteen seconds. Rainbow Dash laughed at this, and Chrysalis flailed her hooves helplessly. Pinkie Pie got up, and Rainbow Dash sat on Chrysalis's face and farted on her again. This fart was unusually airy, but lasted fourteen seconds and smelled awful. Chrysalis's hooves stopped flailing only three seconds after the fart.
Rainbow Dash got up and Pinkie Pie prodded the motionless changeling queen with her hoof. "Is she dead?"
"She's just fainted," said Rainbow Dash, who could see her chest moving. "I guess I win the farting contest!"
"What should we do with her?"
"Let's tie her up and fart on her some more when she wakes up!"
