The camera panned onto a sunny, romantic-looking beach-- although one that was oddly barren of people, other than a single blonde-haired, blue-eyed child wearing a pool floatie.

"Ah, fun at the beach, this is just the job for swim diapers, right?" The camera panned down to his crotch, clad in an ordinary blue swim diaper.

"Haha, wrong!" He pulled it off, and let the flimsy excuse for a diaper dangle from his finger. "Swim diapers are just a Jewish scam to sell you less diaper for more money. Just wear your goddamned Pailful Pants!"

He dropped it and pulled a Pailful Pants diaper out of nowhere, putting it on and taping it up tight. "It's totally up to the task~" The tide suddenly rose and engulfed his diaper with a surge of water. It rapidly absorbed the water, becoming totally soaked. 

"Sure, in this state it won't exactly contain pee, but the literal point of a swim diaper is to not be absorbent. Besides, you got more to worry about in water than a little pee." He waddled back out of the water, showing a better view of the saggy, gel-packed diaper. "It may get super big-- But if you can't handle that, why are you even wearing a diaper, you weakling? You aren't worthy, dysgenic mongrels like you had best use toilets instead."

His tummy gurgled. "But I digress. A diaper like this is still great for pooping." He squatted and immediately pushed out a massive, firm log into his diaper that then settled into the seat of it. With many cacophonious farts he filled it to the brim, causing it to become obscenely droopy with all the poop in addition to the water weighing it down. "Hngggg~" With one final, huge push he caused it to thud against the ground. 

"Ah~ And it feels so good." He rubbed the sack of bloated padding strapped to his waist. "So if you're not a retard and like big diapers, pick Pailful Pants."
