(A/N: Another roleplay piece, this one should make you laugh)

Dipper walked through the strange town with his sister, his nose in journal 3. They had been walking through the town, just taking a stroll, when suddenly, the color was drained from the world around them and an especially annoying equilateral being appeared before them.
"Hiya Pinetree and Shootingstar!! How's the paranormal research goin'?"
Dipper sighed as he looked up from his book. "What do you want this time Bill?"
The demonic dorito had been showing up more frequently ever since Stanley was released from the portal. He would always try to postpone any paranormal findings as long as he could, but who could blame him? The more they found out about this town, the more danger Bill would be in.
The demon chuckled, floating around the twins. "Why, I'm just visiting my favorite little mortals! Is there any harm in that?" "Go away Bill," The female twin interjected,"You aren't wanted here!" The triangle, putting one hand on his "heart" replied to Mabel,"Oh, I'm so hurt! How could you say such a thing, Shootingstar?" "Because you say mean stuff to us all the time, and we have names you know? I'm Mabel, and he's Dipper."
The demon stifled a laugh. "Diaper?" "Dipper!" Mabel interjected, yet again. "And you're sure it's not Diaper?" Bill snickered. "No, it's pronounced Dipper, not Diaper!" "Okay, HEY DIAPER!" Dipper looked up, glaring at the demon.  "What?" Bill slowly reached over and poked dipper in the face. "You just reacted to being called Diaper." The brunette stopped and his face flushed a deep Crimson. He slowly closed his book and walked away.
Bill couldn't hold it in any longer and started to laugh hysterically, his eye becoming teary and barely breathing. Dropping to the ground, Bill continued to laugh. "D-Diaper wait!-PFFFTAHAHAHAHAHA-" after watching Bill roll around on the floor laughing for a couple minutes, she couldn't handle it anymore. Mabel's mouth became a wide smile, resulting in her dropping to the ground and laughing beside her enemy. She couldn't help it, the demon's laugh was just too contagious.
From then on, Dipper was formerly known, by the demon, as Diaper, and he hated it.
