Tests an AI's ability to solve a simple but potentially confusing logic puzzle
I need to figure out how many sisters Sally has.
Given information:
Now, each brother has 2 sisters.
If each of Sally's brothers has 2 sisters, and Sally is one of those sisters, then there must be one more sister besides Sally.
Let me verify:
Therefore, Sally has 1 sister.
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.

Why don't scientists trust atoms? Because they make up everything!
I told my wife she was drawing her eyebrows too high. She looked surprised.
Why did the scarecrow win an award? He was outstanding in his field.
I'm reading a book about anti-gravity. It's impossible to put down.
Why don't eggs tell jokes? They'd crack each other up.
Answer: All 5 jokes are unique. Each one has a different setup and punchline, covering different topics (atoms, eyebrows, scarecrows, gravity, and eggs).
Here are 5 jokes:
Why don't scientists trust atoms? Because they make up everything!
What do you call a bear with no teeth? A gummy bear!

[Walking on stage]
So I turned 35 last month, and I've realized something important: adulting is a scam. It's a pyramid scheme, and our parents are the ones who recruited us.
You know what nobody tells you about being an adult? How much TIME you spend just... waiting for repair people. I've spent more hours of my life waiting for the cable guy than I spent getting my college degree. And it's always a "window" – they'll be there between 8 AM and 4 PM. Oh great, thanks! I'll just put my entire life on hold. That's only eight hours. That's just a full work day of staring out my window like a dog whose owner left for groceries.
[pause]
And they NEVER come at the beginning of the window. Never. You KNOW they're coming at 3:58 PM. But can you leave? No! Because the ONE time you go to the bathroom, that's when they'll knock, wait 0.3 seconds, slap a "Sorry we missed you" sticker on your door, and vanish like a ninja.
[gesturing]
Speaking of things nobody prepared us for – does anyone else feel personally attacked by how often you have to buy toilet paper? I swear I just bought toilet paper. Where does it GO? I live alone! I'm not eating it! But every week I'm at Costco, loading up another 48-roll pack like I'm prepping for the apocalypse. And you can't just buy a LITTLE toilet paper. That's not an option society gives you. It's either 48 rolls or one sad single roll at a gas station that costs $7 and feels like sandpaper.
[shaking head]
But here's what really gets me about being an adult: insurance. Home insurance, car insurance, health insurance, life insurance, phone insurance, TRAVEL insurance. At what point did we all just accept that we're living in a protection racket?
I got a letter from my health insurance last week – you know those ones that say "This is not a bill"? Yeah, those. Why do they send those?! It's just a letter to give me a heart attack, which I then can't afford to treat because of my deductible. It says, "We paid $340 for your recent doctor's visit." My doctor's visit was 11 minutes long. I've had meaningful relationships that lasted shorter than that, but at least they didn't cost $340.
[mimicking reading]
And it's always in that confusing insurance language: "Amount charged: $1,200. Negotiated rate: $340. You owe: $150. Amount we paid: $190. Good luck understanding any of this: priceless."
[shifting topics]
You know what else is a scam? Recipes online. You can't just GET a recipe anymore. Oh no. You have to scroll through someone's entire life story first.
[mimicking typing and scrolling]
"How to Make Toast. Well, let me tell you about the first time I had toast. It was a crisp autumn morning in Tuscany, 1987. My grandmother, who was one-quarter Italian and three-quarters passive-aggressive, used to say..."
JUST TELL ME HOW LONG TO PUT THE BREAD IN THE TOASTER, JENNIFER.
[building up]
There's 47 photos of the same piece of toast from different angles. Toast at sunrise. Toast with a rustic napkin. Toast held by someone's hand with perfect nails. It's TOAST! You put bread in a toaster! This doesn't require a documentary!
[calming down]
But the real sign I've become an adult? I get excited about kitchen appliances now. I bought a new sponge last week, and I was GENUINELY thrilled about it. I called my friend. "Dude, this sponge has a scrubby side AND a soft side!"
Twenty years ago I was sneaking into clubs with a fake ID. Now I'm bragging about sponge technology.
[reflective]
My parents always said, "Just wait until you're an adult, you can do whatever you want!" You know what I do with my freedom? I eat cereal for dinner and feel guilty about it. That's my rebellion now. Sometimes I have ice cream before the cereal, and I feel like I'm getting away with murder.
[final thought]
But I guess that's being an adult. It's just being tired all the time, waiting for repair people, buying toilet paper in bulk, and getting excited about organizational containers from Target.
The dream is dead, folks. But hey – at least we can have ice cream for dinner.
[wave and exit]
Thank you, you've been a wonderful audience! Good night!
"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!
