Leonard and Penny were watching 'Zootopia' in their living room, it was just one of those films they easily agreed upon. Suddenly, Sheldon and Amy came into their apartment.
"You will never guess what happened!" Sheldon exclaimed.
"You two are adopting a cat," guessed Penny as she paused the movie.
"Nope, guess again," answered Sheldon with a disapproving look.
"You're adopting a Chinese child?" asked Leonard with a bit of a sarcastic smile.
"Well, we're definitely not doing that, just tell them Sheldon," said Amy.
"Very well, Cal Tech is sending a well-esteemed scientist from a small town called Royal Woods, Michigan to do some research here, and they asked if I'd be willing to work with her," said Sheldon.
"Are they trying to punish the scientist for some reason?" asked Leonard with a laugh.
"That was so funny, I forgot to laugh. Did I use sarcasm correctly?"
"Yes Sheldon, sweetie you did. I obviously wouldn't know her, but what's the scientist's name?" asked Penny curiously.
"Well, her name is Lisa Loud. I've read some of her research and I must say, it's beyond brilliant! But for some reason, they didn't give me a photo of her. They just said we might get along well," said Sheldon, a bit of intrigue on his face.
Three days later, Sheldon and Penny were at the airport holding a sign that read 'DR. LISA LOUD' on it. They looked at all the people coming through, trying to guess who their mysterious guest was.
"Penny I just want to say thank you for agreeing to drive me here, and for agreeing to meet Dr. Loud. Considering that is what you're supposed to do in this type of situation," said Sheldon.
"Hey no problem. That's just what being a neighbor means, when you happen to be that neighbor," said Penny, she was used to having to drive Sheldon places. She then looked ahead at two girls, one was about four wearing oversized glassed and a green sweatshirt with messy, brown hair. The other looked around sixteen wearing a light green blouse, sunglasses perched on her head and well-combed blonde hair. She noticed they were both wearing 'Unaccompanied Minor' badges.
"Oh, look Sheldon, those two must be sisters," Penny pointed them out.
"Right, y'know if I had ever traveled like that when I was a kid, there's a good chance my mother would've left me at the airport with a prayer and might've had to be dragged off by my father while she would keep trying to hug me. Glad I never had to do that," replied Sheldon.
"I don't think my parents would've been keen on trusting me traveling by myself when I was a teenager," laughed Penny. That's when they noticed that both girls were walking right towards them with two large suitcases.
"Oh my gosh, that blouse you're wearing is totes adorbes!" the tall blonde told Penny.
"Well, thank you, I like yours too. So, are you two meeting some family here?" Penny responded, trying very hard to sound polite.
"No, not exactly," the blonde replied.
"Ah, sho you musht be Dr. Sheldon Cooper. I've read about your work on dark matter and I must say that's amazing! I'm Lisa Loud. Thish ish my older shishter Leni who volunteered to be my chaperone, against my better judgement," the four-year-old finally said. Sheldon and Penny were surprised! To say nothing of the fact that they didn't hide it, they dropped the sign they were holding.
"Oh here, let me get that for you. I just couldn't turn down the chance of seeing sunny California!" said Leni as she picked up the sign.
"So, you're the one who did all that revolutionary research on how fungi and molds develop quicker in an overcrowded home?" asked Sheldon.
"Among other thingsh. With what I have to work with, it wasn't difficult," replied Lisa as she adjusted her glasses.
"OMG! I'm so gonna do a selfie with all of us!" said Leni who quickly lifted Lisa up with one arm and took a selfie with their new friends. Penny at least smiled but Sheldon just looked nervous.
"Well, let's not hang out at the airport all day, shall we go?" asked Penny. Everyone agreed, and Penny took both of the girl's suitcases, knowing Sheldon would just complain about the weight.
"Just out of curiosity, what is the cut off age for those 'unaccompanied minor' buttons? I didn't realize they gave them to sixteen-year-old's," asked Penny.
"Believe me, it was a lot shafer to have Leni wear one. I jusht wore mine becaushe I wuz required to. Note to shelf, musht thank Cal Tech for paying for both ticketsh," replied Lisa.
