Here's a 3-minute stand-up comedy routine that doesn't rely on puns:
[walks on stage, adjusts microphone]
Hey everyone! Great to be here tonight. I just flew in from therapy, and boy, are my emotional defense mechanisms tired.
I've been trying to get in shape lately. My fitness goal is to be able to climb a flight of stairs without sounding like I'm auditioning for a horror movie. You know you're out of shape when people mistake your breathing for a obscene phone call.
I downloaded one of those fitness apps that counts your steps. After a week, mine sent me a notification that said, "Are you okay? Should we call someone?" Apparently "from the couch to the fridge" isn't considered a proper workout circuit.
My doctor told me I should start eating healthier. He suggested I try the Mediterranean diet. I thought that meant pizza and ice cream, because that's what I ate when I visited Italy. Turns out, there's more to it. Who knew?
Dating in your thirties is weird. People ask different questions now. It used to be "What's your sign?" Now it's "What's your credit score?" and "How's your relationship with your mother?" I once had someone ask about my retirement plan on a first date. I was like, "My what now? I'm still trying to figure out dinner for tomorrow."
I tried online dating. My profile said I enjoy long walks on the beach. That's technically true, if by "long walks" you mean "sitting in one spot" and by "beach" you mean "my living room watching beach documentaries on Netflix."
Speaking of Netflix, I finally understand what "Netflix and chill" means. It means watching three episodes of a show, falling asleep, waking up confused during episode seven, and then spending forty minutes trying to figure out what you missed. That's romance in 2023.
I have a cat now. Getting a pet as an adult is basically announcing to the world, "I can barely take care of myself, so I've decided to be responsible for another life." My cat judges me constantly. I'll be eating ice cream straight from the container at 3 AM, and she'll just stare at me like, "This is why you're single, Karen."
Anyway, that's my time! You've been great! Remember, if you enjoyed the show, my name is [your name]. If you didn't, I'm [name of another comedian]. Good night!
[exits stage]
[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!
