Laxative

 Sure! Here's a rewritten version that keeps the story lighthearted and humorous, adds more character dialogue and internal thoughts, and includes the bathroom chaos with vivid (but still PG-13 level) descriptions. This version balances the gross-out humor while staying fun and family-friendly:

Leo and John’s Ultimate Prank on Dad

Leo and John were two mischievous brothers — notorious around the house for causing chaos. But if you asked them, they’d say, “We learned from the best.”

Their dad, a burly 50-year-old with a round belly, white beard, and a mischievous twinkle in his eye, was the undisputed prank king. From fake spiders under pillows to jump-scare traps behind doors, he lived for practical jokes.

“Remember when he switched our toothpaste with mayonnaise?” John muttered one afternoon.

Leo shuddered. “My tongue still hasn’t recovered.”

“Well,” John said, grinning, “I think it’s time for payback.”

Leo’s eyes lit up. “Operation Chocolate Thunder begins.”

The Setup

That evening, while their dad was lounging in his recliner watching TV and chuckling at a rerun of America’s Funniest Home Videos, the boys went to work in the kitchen.

John whispered, “Two scoops of ice cream… one scoop of revenge.”

Leo uncapped the bottle of chocolate syrup — and next to it, a small bottle of liquid lightning (aka fast-acting laxative).

“Think this is too much?” Leo asked as he poured a generous glug into the milkshake.

“Nah,” John said, chuckling. “He deserves a thunderstorm.”

They blended it up and brought it over like two innocent little angels.

“Hey, Dad,” Leo said, “We made you your favorite.”

“Oooh, chocolate milkshake?” their dad said, eyes lighting up. “You boys are finally learning how to treat your old man right!”

He slurped it down in minutes.

The Storm Builds

About 15 minutes later, Dad’s face twitched.

“Hmm…” he muttered, rubbing his belly. “Did you boys use… oat milk?”

Leo fought back a laugh. Here it comes.

Suddenly, a long, wet-sounding fart broke the silence.

BRRRRRRRBBBBBBTTTTTT.

Dad’s eyes widened in panic. “Uh-oh.”

John whispered, “T-minus 10 seconds.”

His dad shot up from the recliner, waddling at warp speed toward the bathroom.

“Move! Move! Coming through!” he shouted, gripping his stomach.

He barely made it. As soon as the door slammed shut—

SPLORRRRRT!

“OH LORD!” he yelled from inside.

Leo had already positioned a phone just outside the cracked door. John whispered dramatically, “We are live at ground zero.”

From inside the bathroom came a symphony of regret.

“Ohhh nooo… what was IN that shake?!” their dad groaned.

PHBBBLTT! SPLATTTT!

Leo could barely breathe from laughing.

“I can hear it echoing off the tiles,” John whispered, wheezing. “He’s melting!”

The Aftermath

Ten minutes and three air freshener sprays later, their dad emerged, pale but smiling.

“You little demons,” he said, wagging a finger. “You think this is funny?”

“Yes,” Leo said. “Very.”

“Too funny,” John added.

Dad pointed at them like a general about to declare war. “It’s on now. You’ve just declared prank war. I hope you sleep with one eye open.”

As he waddled back to the couch, still rubbing his belly, another pffffrrrttt slipped out.

“Oops,” he said, smirking. “Collateral damage.”

The boys burst into fresh laughter.

And from that day on, the prank war officially escalated to new — and slightly stinkier — levels.
