Karl took a few seconds to regain his sanity after just seeing a TALKING PINK PONY yell right in his face. When he really considered it, the initial greeting was much greater a shock to him than arriving in an alien world via his telephone while talking to his friend that was supposed to be on holiday that had a random voice change during the call. Compared to this pony in front of him, all of that other stuff was a typical morning.
Karl gathered his thoughts and prioritized his possible responses to give this apparently sentient and talking pony. He decided knowing exactly where he was was the most important thing, since "Pinkie Pie" had introduced herself already and he knew how he got here. That was the who and the how, he just needed the why and the where. The why would come later.
"Where did you say we where?"
Pinkie put on a huge smile, as she always does when she gets excited about explaining things to new visitors. "This is Ponyville, which is in Equestria. Actually, if you wanna get technical about it, this is a field; Ponyville is down the road a little ways."
Karl let that sink in for just a moment before a sudden realization came to mind. He found it quite hilarious, and it even put a smirk on his face. Pinkie was happy to see the new visitor smiling and couldn't wait to hear what he was smiling about.
"Wait a moment, the land of ponies is called Equestria..."
"Yup!" Pinkie replied.
"And they live in Ponyville! What's next? Is there a Manehattan or a Canterlot or a Trottingham?" Karl couldn't help chuckling after saying each city name.
"Of course! Some of my bestest friends live in Canterlot!" Pinkie was a little confused, she didn't see what was so funny about Canterlot or Manehattan to this visitor. They were perfectly normal city names. Karl just started laughing like a madman in front of her and Pinkie had no idea why.
"There's actually a... a real city they named..."
"Yeah, what's so funny?" Pinkie was all for laughing for no reason, but she didn't like this vibe that Karl was sending out; it was like he was insulting the names rather than just laughing at something that isn't funny. She didn't get what was so insultable or comedic about Canterlot.
"Let me guess... Manehattan is the center of fashion and musicals in the country, and Canterlot is where the royal family and the knights and all that live?"
"Actually, yeah, that's about right." Pinkie was really surprised now, and that was no small feat. If this stranger really didn't know about Equestria and suddenly arrived here or got lost here and has amnesia, why can he so accurately guess the names of cities and know exactly what goes on there? Does he have a Pinkie sense for cities like she does for random events? And most importantly, WHAT WAS SO FUNNY!?
Karl kept laughing for another thirty seconds before he got it out of his system.
"Sorry, sorry, moving on..." Karl thought about other questions he should ask, and decided the biggest problem would be where he was going to stay while he was in 'Equestria.' "So, are there any hotels or inns or anything like that in town I can stay tonight? I don't quite fancy sleeping outside in strange places at night where I don't quite know the bug situation or the crime rate."
"You don't have anywhere to stay tonight?!" Pinkie thought for a moment about this, and then started thinking out loud. "Let's see, you could stay with AJ, but she' having family over this week, so she doesn't have any rooms available. Mr. and Mrs. Cake don't like it when I bring random strangers to spend the night, let along spend a few nights. I don't think you can fly, so staying with Dashie is right out. Rarity is really busy working on her new clothing line this week, so she's out too..."
'So, apparently, I just got out of staying on a farm, with this one, and with a clothing designer. Things are going better than expected so far,' Karl thought to himself.
"OOOOOH! I got it! You can stay with princess Twilight! I bet she'll be really interested to see you!"
'Oh, really, staying with royalty this time? And royalty that's interested to see me, nonetheless? I think I'm going to like it here after all.'
"By the way, I never did ask your name."
"Oh, my name's Karl, Karl Pilkington."
