Tests an AI's ability to solve a simple but potentially confusing logic puzzle
I need to work through this step-by-step.
Given information:
Since Sally is one of the sisters that each brother has, and each brother has 2 sisters total, that means th ere must be exactly 2 sisters in the family.
The 2 sisters are:
Therefore, Sally has 1 sister.
Let's break down the problem:
Let's analyze:
Sally's siblings:
The brothers' sisters:
Who are the possible sisters for each brother?
If Sally is the only girl, then each brother would only have 1 sister (Sally). But the problem says each brother has 2 sisters.
Therefore, there must be another sister besides Sally.
Let's check: Suppose Sally has 1 sister (besides herself). So the siblings are:
Children in the family:
Now, for each brother:
So, Sally has 1 sister.
Final answer:
[ oxed{1} ]
Sally has 1 sister.

"Modern Life is Weird"
[Walk on stage]
You know what's crazy about being an adult? Nobody tells you that half of it is just googling things you're too embarrassed to ask real people. Last week I googled "is it normal for my knee to sound like bubble wrap? " The answer was either "yes, totally fine" or "you have six weeks to live." Thanks, internet!
[Pause]
I went to the doctor about it. You know you're getting old when your doctor looks like they should be asking YOU for ID to buy alcohol. This kid walks in with a stethoscope, and I'm like, "Did you just graduate... fr om middle school?"
But here's what really gets me – why do we act completely insane at the doctor's office? They ask, "How much do you drink?" and suddenly I'm doing calculus in my head. "Well, let's see, carry the one... I have a glas s of wine with dinner." Yeah, a glass. It's just a really big glass. It's a vase, actually. I drink wine fro m a vase.
[Mime drinking from large container]
And don't get me started on grocery shopping. Why do I need a PhD to buy shampoo? There's moisturizing, volu mizing, clarifying, fortifying... I just want my hair to be clean! I don't need it to solve my emotional pro blems!
Plus, self-checkout is a trap. They put you in charge of scanning your own groceries like you work there. Th en the machine starts screaming "UNEXPECTED ITEM IN BAGGING AREA!" Yeah, it's unexpected because I don't wor k here! I'm doing my best, robot!
[Pause for effect]
The worst part is when you're buying embarrassing things. Last week I had toilet paper, ice cream, and cat f ood. The machine froze, and the teenage employee had to come over. He looked at my items and I could see him thinking, "This person's having a rough week."
[Shrug]
Speaking of technology, my phone knows too much about me. It autocorrects "running late" before I even type it because that's apparently my catchphrase now. My maps app just assumes I'm lost. It doesn't even wait for me to ask for directions anymore. I'll be sitting on my couch and it's like, "Turn right to get to your kit chen."
And what's with password requirements these days? "Must contain uppercase, lowercase, numbers, symbols, the blood of your firstborn, and a haiku about your childhood fears." Then they're like, "Don't write it down!" Where am I supposed to store this information? I can't remember why I walked into a room!
[Pace across stage]
You know what else nobody prepared me for? How excited I'd get about cancelled plans. Someone texts "Hey, ca n we raincheck?" and I'm already in my pajamas like "Oh no! What a shame! I was so looking forward to puttin g on real pants!"
Because going out now requires preparation. I need three business days' notice. I need to charge my social b attery. I need to practice conversation topics. Remember when we could just... show up places?
[Final beat]
The truth is, we're all just walking around pretending we know what we're doing. But at least we're all conf used together. And hey, if you ever see someone at the store at 10 PM buying wine in a box and googling "why does my back hurt when I breathe?" – just give them a nod. We're all in this together.
[Pause]
Thank you, you've been a wonderful audience! Don't forget to validate your parking – unlike my life choices!

Absolutely! Here's a 3-minute stand-up routine with no puns—just observational and relatable humor:
You ever try to get healthy, but your body's like, "Whoa, whoa... calm down, superhero." I joined a gym—first time walking in, the treadmill looked at me like, "We both know you're here for the wifi." They hand me a to wel and I'm like, "Oh, I'm not gonna work up enough sweat to justify this, but thanks for believing in me." I try eating salads. I don't understand people who say salads fill them up. I finish a salad and immediately want to reward myself—with a pizza. The salad's just the job interview, the pizza's what brings me real joy . That's why my salad always comes with a side of fries. My body's like, "You remember vegetables, right? In troduce them to their friend, carbohydrates."
Ordering food is hard. Restaurants make everything so customizable now. "Do you want that grilled or fried? Pick your bun, pick your sauce, choose your mood for the day." By the time I'm done I feel like I've taken t he SATs. And that's before they ask about up-sizing. "Would you like to upsize for just a dollar?" I always say no—because I'll pay twice that much in guilt.
Dating apps are even worse. Your thumbs do more cardio than your legs. Swiping is the new stairmaster. Profi les always say, "Love to travel!" I match with you, you mean going to Target in a different zip code. Why do we act like flying to Portugal is our hobby? Meanwhile, my idea of exploration is getting up to find the re mote.
I tried meditating because they say it's good for stress. My head is full of thoughts. The app says, "Let yo ur thoughts float by like clouds..." Suddenly all my clouds are bills. Student loans, dental bills—I'm basical ly in a storm.
And then there's technology. My smart watch knows I've been sitting for too long. Every hour, it vibrates, " Time to move!" It's like a parole officer living on my wrist. I miss the days when only my conscience judged me for lying on the couch. Now I have a device, "You've walked 32 steps today... are you...are you okay?"
But in the end, I'm trying! One salad at a time. One step. One dating profile. And sometimes, one slice of p izza. Because let's be honest—no one ever had a life-changing moment during a salad.
Thank you, everybody!
