At the Mystery Shack, the family was discussing dinner plans for tomorrow.
"So, where do you guys wanna go tomorrow?" Grunkle Stan asked. "Any ideas?"
"Oh, can we do to McDonald's?!" Mabel asked excitedly.
"Yes! McDonald's!" Dipper exclaimed, agreeing with his sister.
"Wait, did someone say McDonald's?" Soos asked, poking his head through the doorway. "Are we actually going there? Oh my god! They literally serve the best stuff over there, dude!"
"Well, the kids want to," Stan stated. "And it looks like you want it to, Soos, so we're going there tomorrow."
"YAY!" The twins and Soos cheered.
"Wait.. McDonald's?" Ford Pines, Dipper and Mabel's other great uncle, paused in writing a few notes down in his journal and looked up at the family, confused. "What is that?"
Everyone turned to look at him.
"Oh my god! How could you not know what McDonald's is? It is like the best place to eat ever!" Soos stared at Ford like he was an idiot.
"Soos, he's spent 30 years trapped in another dimension! Of course he doesn't know what it is!" Stan scoffed.
"Oh right," Soos nodded his head.
"Well Grunkle Ford," Mabel looked up at her Grunkle Ford with a smile. "McDonald's is a special place where they serve really good food!"
"Yeah, your mouth will literally exploded from it's tastiness!" Dipper explained joyfully.
"Alright, alright. It's been a long day and we all gotta rest for another day tomorrow," Stan said. "Now come on, on to bed with all of ya!" Stan ushered everyone out of the room. He turned back to see his brother staying behind. "You going to bed, Poindexter?"
"No… I'll, uh… just.. Uh, stay behind and finish some work," Ford told his brother.
"Fine. Just don't stay up too long. A grown man like you has to rest, too," Stan informed him before he went up the stairs to his room.
However, Ford wasn't focused on his work. He was thinking about McDonald's and what the kids had told him about it. Do the stuff there really taste good? He wondered. Do they literally explode in your mouth? Ford was really curious and decided right then and there to go investigate right away and see if it was true.
And so, Stanford Pines packed up his notes, carefully sneaked out of the shack so as not to wake anybody and setted off to find a McDonald's to see for himself and investigate the food over there.
