[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!

Hey everyone. How are we doing?
I’ve realized recently that I’m not actually an adult. I’m just a toddler with a debit card and back pain. That’s it. That’s the whole experience.
I think the hardest part of modern life is that we have convinced ourselves that we love "convenience." But convenience is just stress in a faster format.
Take self-checkout at the grocery store. Who designed this experience? It’s the only place where I can be a paying customer and an incompetent employee at the same time. I’m scanning my stuff, feeling good, and then I put a single apple in the bag, and the machine screams at me.
"UNEXPECTED ITEM IN THE BAGGING AREA."
It’s so accusatory! It’s like the machine has trust issues. I’m standing there holding a banana like, "I swear, it’s just fruit! I’m not trying to heist the Kroger!"
Then the red light starts flashing. The "Light of Shame." Now I have to wait for the one actual human employee, who is managing twelve robots, to come over. She sighs, swipes a card, and looks at me like I don’t know how gravity works. I didn't steal the apple, Janet, the scale is just gaslighting me!
(Pause for laughter)
And it’s not just the physical world. The digital world is trying to break me, specifically with passwords.
Do you remember when a password could just be "Password123"? Now? You try to create an account to buy socks, and the security requirements are harder than getting into the Pentagon.
"Your password must contain an uppercase letter, a lowercase letter, a number, a special character, and the blood of a virgin."
I’m just trying to buy ankle socks! I don’t need Fort Knox security.
And then, inevitably, I forget the password. So I click "Forgot Password." And the computer says, "Okay, no problem. You can reset it... but you cannot use any of your previous three passwords."
Excuse me? Why do you remember them? If you know what they are, just let me in! Clearly, we both know the secret code!
(Walks a bit across the stage)
I think all this stress is why I’ve started obsessing over sleep. That’s the final stage of adulthood: spending an insane amount of money on bedding.
I bought a pillow last week. It cost eighty dollars. Eighty dollars! For a bag of foam. But the marketing got me. It said it was "Memory Foam."
I don’t know why I want my pillow to have a memory. I drool when I sleep. I don't want the pillow remembering that. I want a pillow with amnesia. I want a pillow that wakes up every morning going, "Who are you and why are you damp?"
The box said it was "Ergonomically designed for side sleepers." I bought it, took it home, and realized it doesn't matter what shape the pillow is, because I sleep like I fell off a building. I wake up with my arm twisted behind my back, one leg off the bed, and my neck at a ninety-degree angle.
I woke up this morning and it took me three minutes to initialize my own spine. I sounded like a bag of gravel being thrown down a staircase. Crack. Pop. Snap.
But, you know, I got up, I drank my coffee, and I reset my password again. So, I guess I’m doing okay.
Thanks, guys, you’ve been great!
