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.

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!
What do you call a fake noodle? An impasta!
Why don't eggs tell jokes? They'd crack up!
All 5 jokes are unique - each one has a different setup and punchline, covering different topics (atoms/scie nce, bears, scarecrows, pasta, and eggs).

Why did the bicycle fall over? Because it was two-tired!
As for your question: All 5 are unique — each joke has a different setup, punchline, and subject. No two are duplicates or variations of the same joke.

"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've been using those AI assistants a lot lately, and I realized something terrifying. The AI knows me better than I know myself.
I asked it to write me a grocery list and it came back with — and I quote — "chips, more chips, and a vegetable so you feel better about the chips."
That's not a grocery list. That's a psychological profile.
I tried to get healthy recently. I downloaded one of those fitness apps that tracks everything. Steps, calories, sleep, heart rate. Everything.
Day one, I'm feeling motivated. I go for a walk. The app says, "Great job! You've completed four percent of your daily goal."
Four percent.
I walked to my mailbox and back. The app looked at that and essentially said, "Buddy, we need to talk."
The sleep tracking is the worst part. I wake up and the app tells me how I slept. Like I need a second opinion on that.
I KNOW how I slept. I was there.
"You spent forty minutes in deep sleep and six hours just sort of... existing." Yeah. That's called being an adult. We don't sleep anymore. We just lie down and worry horizontally.
My phone now interrupts me to tell me I've been on my phone too long.
Think about that. The phone is concerned about me. The phone has drawn a boundary.
I've been in relationships that never reached that level of self-awareness.
"Screen time is up thirty percent this week." Okay but in my defense, I was reading. "You were watching a man fall off a skateboard for two hours." ...It was the same man. I got invested.
I tried meditation to deal with the stress. Downloaded a meditation app — because apparently the cure for too much phone is more phone.
The app has this calming voice that says, "Clear your mind of all thoughts."
And my brain goes, "Okay. No thoughts."
Two seconds later: "Did I leave the stove on? What IS a mortgage, really? Why do they call it a building if it's already built?"
The app says, "You're doing great."
It's lying. The app is lying to me and somehow that's the most comforting thing anyone has said to me all week.
I think that's the thing about modern life. We've built all this technology to make us feel better, and mostly what it does is hold up a very precise, data-driven mirror and go, "Look at yourself."
And we look.
And we go back to the chips.
Thank you, you've been wonderful.
