[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!
[Comic steps on stage, takes the mic]
“Hey everyone, thanks for coming out tonight. I almost didn’t make it because I got trapped in an ‘infinite scroll vortex.’ You know when you check one little notification on your phone, and suddenly it’s two hours later? My left thumb is basically a professional athlete at this point—I'm in the Guinness Book of World Records for ‘fastest social media refresh.’ I feel like every time I tap my screen, I’m signing away another portion of my soul. But hey, at least I’m caught up on all my ex’s vacation photos and some random cat videos I can’t unsee.
So I got myself out of the house and decided to try being more ‘active.’ I went to one of those fancy gyms—where the equipment is shinier than my future. The treadmill is so high-tech it practically demands a DNA sample before you can start running. I’m standing there huffing and puffing while the machine's screen is playing scenic videos of mountains in Switzerland, encouraging me to ‘keep going.’ Meanwhile, I’m like, ‘Dude, I’m just trying not to collapse. Maybe ease up on the pep talk.’
After that, I thought I’d reward myself with a healthy smoothie. Have you seen the sizes of these things? You order a medium and you get a bucket of kale sludge. They hand it to you with a straw so wide you could drive a toy car through it. And suddenly you’re paying nine bucks to sip spinach—like that’s the best life decision you’ve made all day. Who needs retirement savings when you can have a fancy green drink that tastes suspiciously like lawn clippings?
On the way home, I got stuck in traffic. I just love that feeling when you’re gridlocked behind two people who are evidently in no rush to do anything, ever. I’m sitting there, going about two miles an hour, which is basically just a very aggressive crawl. I’m not proud of how often I shout at my windshield. My car is like my personal confessional booth, and the traffic jam is me atoning for all the times I told Netflix, ‘Yes, I’m still watching.’
Anyway, that’s me, folks. If you’ll excuse me, I have 47 unread notifications that I need to pretend don’t exist until tomorrow. Thanks so much for laughing along—and remember, if you want to feel accomplished tonight, just check something off your to-do list… or, you know, at least make one.” [Comic waves and exits the stage]
