Here are 5 jokes:
Why don't scientists trust atoms? Because they make up everything!
Why did the scarecrow win an award? Because he was outstanding in his field!
What do you call a fake noodle? An impasta!
Why don't eggs tell jokes? Because they'd crack each other up!
What did the ocean say to the beach? Nothing, it just waved.

Sure—here are five jokes:
All five are distinct. Number of unique jokes: 5.

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!
[Comedian walks onstage]
Hey, everyone! Great to see you all tonight. I'm Jamie—if you thought that intro was enthusiastic, you should've seen me when I realized this place has Wi-Fi.
Seriously, though, I love stand-up. For one thing, I get to share all the weird stuff I secretly do in my apartment… and instead of calling the cops, you guys just laugh. That's high-quality entertainment right there.
So, the other day I'm in the self-checkout lane at the grocery store—because I'm the kind of person who's thrilled by the thought of scanning my own kale. Of course, there's always that one person holding up everyone behind them because they can't figure out how to scan a cucumber. Meanwhile, the machine flashes: "UNEXPECTED ITEM IN BAGGING AREA." It's staring at me like it's personally offended that I tried to buy almonds in instead of potato chips. I'm over here trying to reason with it:
"Look, buddy, I'm just trying to eat slightly healthier. Isn't that what we all want?"
Then it asks me, "Do you want a produce discount?" The only discount I want is one that lets me leave this line five minutes ago. I press "No," and the machine glares at me with a red light and calls for help like I'm smuggling avocados under my shirt.
My phone has ruined me. I can't have any thought longer than three seconds without Instagram interrupting me. I'll be in the shower—fresh shampoo, head full of suds—and in my brain:
"Did my neighbor's cat post another selfie? I need to check."
Fifteen minutes later I'm drying off, scrolling through cats wearing sweaters. Why are cats always more photogenic than me? They don't even try. They're just like, "You feed me, you click 'Like.'" I wish I could have a boundary like that—"Hey, you gave me pizza once; you can go ahead and like my vacation photos."
Anyone here stuck in a group chat you can't escape? There's always that one friend who forwards the exact same video one hundred times, and everybody else thinks it's the highlight of their week. I just mute my phone like it's an ex sending memes at 2 a.m. Then I wake up at dawn, bleary-eyed, thinking, "What did I miss?" I open my phone—and it's Bob celebrating his new air-fryer chicken recipe for the fifth time. Meanwhile, I burned my eggs so badly this morning that my smoke alarm filed a restraining order against me.
I decided to get in shape. I downloaded one of those workout apps promising "six-pack abs in six weeks." After day one, I collected six new excuses why I can't work out:
Yesterday I finally ran so hard I passed out. When I came to, my neighbor was standing over me yelling, "You know you're not supposed to lean on lampposts, right?" I told him, "As soon as lampposts start offering aerodynamic support, I'll consider trusting them."
Alright, folks, that's my time. If you ever feel judged by a machine or betrayed by a group chat, come find me—I'll be the one in the self-checkout line, trying to convince a barcode scanner that kale is, in fact, a food. Thanks so much—you've been awesome!
