I need to work through this step-by-step.

Given information:

Sally is a girl
Sally has 3 brothers
Each brother has 2 sisters

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:

Sally
One other sister

Therefore, Sally has 1 sister.

Here are five jokes:

Why don’t skeletons fight each other?
They don’t have the guts.
Why did the scarecrow win an award?
Because he was outstanding in his field.
What do you call fake spaghetti?
An impasta.
Why don’t some couples go to the gym?
Because some relationships don’t work out.
Why don’t skeletons fight each other?
They don’t have the guts.

Now, let's check for uniqueness:
Jokes 1 and 5 are identical, so there are 4 unique jokes.

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).

Stand-Up Comedy Routine: "The Quirks of Modern Life"

[Lights up. Comedian walks on stage, grabs the mic.]

"Hey, everyone! How’s it going? Good? Great. I’m here to talk about the weird stuff we all deal with in modern life. You know, the things that make you go, 'Wait, is this normal, or am I just losing it?'

Let’s start with smart devices. I have a smart speaker at home. You know, the kind that’s supposed to make your life easier. But somehow, it’s turned into a passive-aggressive roommate. Like, I’ll say, 'Hey, play my morning playlist,' and it’ll respond, 'Playing The Sound of Silence by Simon & Garfunkel.' And I’m like, 'Wow, even my speaker’s roasting me now.'

And don’t get me started on autocorrect. It’s like having a personal assistant who’s always drunk. I’ll type, 'I’m running late,' and it’ll change it to, 'I’m running llama.' Yeah, because that’s what I meant. I’m late to work because I’m herding llamas. Totally normal.

Speaking of work, can we talk about Zoom meetings? I don’t know who needs to hear this, but if you’re on mute for the entire meeting, you’re not fooling anyone. We all know you’re eating a sandwich or scrolling through TikTok. And that little 'You’re on mute' reminder? It’s the digital equivalent of someone tapping you on the shoulder and saying, 'You’re embarrassing yourself.'

And let’s not forget self-checkout machines. I don’t know about you, but every time I use one, I feel like I’m being tested. It’s like, 'Please place the item in the bagging area.' I did place it in the bagging area! Why are you yelling at me? I’m not stealing a $2 banana! And then the attendant comes over, and I feel like I’ve been caught shoplifting, even though I’m literally paying for my groceries.

Oh, and social media. What even is that anymore? It’s like a highlight reel of everyone’s fake lives. People post pictures of their perfect vacations, their perfect meals, their perfect relationships. Meanwhile, I’m over here posting a selfie with the caption, 'Survived another day without spilling coffee on myself.' Spoiler alert: I didn’t survive.

But you know what’s the weirdest thing about modern life? Streaming services. There are so many of them now, I spend more time choosing what to watch than actually watching anything. I’ll scroll through Netflix, Hulu, Disney+, and Amazon Prime for an hour, only to end up rewatching The Office for the eighth time. At this point, I’m not even watching it for the jokes; I’m just checking in on my fictional coworkers.

And don’t get me started on passwords. I have so many passwords now, I’ve started using the same one for everything. My Netflix password is literally 'Password123,' and I’m just hoping no one hacks me. Like, what are they gonna steal? My watch history of true crime documentaries?

Anyway, that’s all I’ve got for tonight. Thanks for laughing, and remember: if you’re ever feeling overwhelmed by modern life, just take a deep breath, turn off your smart speaker, and eat a banana. Just make sure you pay for it at the self-checkout.

Goodnight, everyone!"

[Lights down. Applause.]

"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]
