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 me work through this step-by-step.
Sally is a girl, and she has 3 brothers.
Each of her brothers has 2 sisters. Since Sally is one of those sisters, each brother has Sally + 1 other sister.
So Sally has 1 sister.

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!
Why did the scarecrow win an award? He was outstanding in his field!

All 5 jokes are unique - each one has a different setup and punchline, covering different topics (atoms/scie nce, bears, scarecrows, pasta, and eggs).

"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!
[Exit]
So I turned 30 last year, and nobody warns you that adulthood is just Googling stuff until you die. That's it. That's the whole thing.
Last week I Googled "is it normal for your knee to just... start making that noise." Not because I injured it. I sat down. I sat down and my knee sounded like someone stepping on bubble wrap in a library. My body is just adding sound effects now. Uninvited.
And you know what the worst part of being an adult is? You have a favorite burner on the stove. Don't lie to me. You know which one heats right. The back left one is DEAD to you. You haven't used that burner since 2019. It's decorative at this point.
I also love how everyone pretends they have a system for Tupperware. You don't have a system. You have a cabinet that you open very carefully, like you're defusing a bomb. One wrong move and an avalanche of mismatched lids buries your cat.
My parents, though — my parents have entered the phase of life where every phone call is a medical update I didn't request. My mom calls me like she's filing a report. "Just wanted to let you know, your father's cholesterol is down, but his doctor is concerned about his sodium, and Linda from church? Hip replacement. Both sides."
I'm like, Mom, I called to ask if you have my birth certificate.
"Oh, I'll have to look. Anyway, Linda's walking again."
LINDA IS NOT MY CONCERN RIGHT NOW, MOM.
And my dad — my dad has discovered texting, which is a nightmare for everyone involved. He texts like every message is a telegram from 1943. Full stops after every word. "Going. To. Store. Need. Anything." I feel like I'm being interrogated.
He also signs his texts. "Love, Dad." I know it's you, Dad. It says your name at the top. We've been over this. He does NOT care.
But honestly, the thing that broke me recently? I got excited about a sponge. I'm not kidding. I bought a new sponge, and I was like, "Oh, this is a GOOD sponge." I showed it to my wife. She was also impressed. We had a moment over a sponge.
And I realized — that's it. That's the barometer now. That's where the bar is for excitement. I peaked at 22 doing karaoke on a rooftop in Austin, and now I'm standing in my kitchen holding a sponge like I just pulled Excalibur from the stone.
The worst part? I'm not even sad about it. The sponge is great. It's got the scrubby side AND it dries fast? Are you kidding me?
I think that's how they get you. Adulthood isn't some dramatic shift. Nobody sits you down and says, "It's time." You just wake up one day and realize you went to bed at 8:30 on purpose — not because you were tired, but because you were excited to go to bed. Sleep isn't rest anymore. It's a hobby.
And you know you're fully gone when you start saying things your parents said, and you don't even flinch. I told a teenager the other day, "You'll understand when you're older." It just came out of me. Like a sneeze. I heard it leave my mouth and I thought, well... that's it. The transformation is complete.
Anyway, I gotta get home. I left a load of laundry in the dryer and honestly I've been thinking about it this whole time.
You've been a wonderful audience. Good night!
