[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!
[Walks on stage, mic in hand, already sweating like a phone at 2% battery.]
Hey, everybody! Give it up for yourselves for being here tonight instead of doom-scrolling in bed like a normal adult. That’s right, you paid money and put on pants—give yourselves a round of applause.
So I’m single. Not “complicated” single, like “it’s complicated” single. No, I’m “the delivery driver asks if the food is for two and I answer ‘not tonight, Jose’” single.
Dating apps are the worst. I swear the algorithm is just three unpaid interns in a basement playing Mad Libs with my dignity. “Let’s match him with a girl whose bio says ‘Looking for the Jim to my Pam.’ Perfect! He’s more of a Toby.”
And the pictures—ladies, why is every photo a group shot? It’s like a police lineup where I’m supposed to pick my future ex. “Number three looks nice, but number four might murder me. Let’s gamble.”
Guys aren’t better. Our profiles are just lies stacked like Jenga blocks. One guy’s pic is him on a yacht. Sir, that’s a pontoon at your uncle’s lake house. You’re not international, you’re interstate.
I tried to seem outdoorsy for the apps, so I went hiking once. Once. I wore sandals because I thought “trail” was short for “retail.” By mile two, my feet looked like I’d been kicking cacti for sport. A squirrel judged me. He was wearing tiny Nikes.
My mom keeps asking when I’m getting married. I told her, “Mom, I can’t even commit to a phone plan.” She says, “Just pick one!” Lady, I picked you thirty years ago, and I still don’t know if that was the right choice.
And now she’s on Facebook, sharing posts like “If your son is over 30 and single, it’s because he’s either gay or a serial killer.” Mom, I’m neither—I’m just lactose intolerant. The only thing I’m killing is the vibe when I ask if the restaurant has oat milk.
Work’s no better. My boss said, “We’re a family here.” Cool, so when do I start getting drunk at noon and pretending to like your potato salad? They gave us “unlimited PTO,” which is corporate for “we’ll fire you in your dreams.” I took one day off and came back to 600 emails and a passive-aggressive sticky note that said, “Hope it was worth it.”
But the real kicker is adulting in general. I went to the DMV last week. The lady at the counter looked at my photo and said, “You know this’ll last ten years, right?” I said, “Lady, I can’t commit to a haircut for six weeks. That’s on you.”
And groceries! Why is everything suddenly “plant-based”? I picked up a package that said “plant-based chicken nuggets.” I flipped it over—ingredients: sadness and yellow dye number five.
I miss the 90s. Back then, the only “plant-based” thing we had was smoking weed behind a Chili’s.
Alright, I’ve kept you long enough. If you enjoyed the show, tell your friends. If you didn’t, tell your enemies—they’ll hate it too. Goodnight!
