Alright, alright, settle down you magnificent collection of human beings! You look good tonight. Not just good, but… like you've all collectively decided to nail the 'I'm here to laugh and avoid talking about my Monday' look. And I respect that.
Seriously though, it's great to be back on stage. I'm living the dream. The dream where I stand under a hot light, tell jokes, and then pray to whatever cosmic entity oversees snack food that someone buys me a churro afterwards. It's a very specific dream.
You know, I've been thinking a lot about the little things lately. Like how we, as a society, have completely lost the art of the proper grocery store queue. Remember when it was an orderly, efficient process? Now it's like a Thunderdome of trolley carts and self-scanning existential dread.
I was at the supermarket the other day, and this woman in front of me had a full-blown argument with the self-checkout machine. Not a quiet, muttering argument, but a shouting match. "I scanned you! You know I scanned you! This is manipulation, Fresh Goods 4000! You're just trying to make me feel inadequate!"
And I'm just standing there, awkwardly holding my single bag of crisps, wondering if I should intervene, like, "Ma'am, perhaps it's time to accept the machine's judgment. It saw what you did with that avocado."
And don't even get me started on the phenomenon of unsolicited life advice. Everywhere I go, someone's got a hot take on how I should live my life. I was at the gym yesterday – yes, I go to the gym, briefly, for moral support – and this guy comes up to me in the middle of a set. He's like, "You know, you're not really getting the full benefit from that curl. You need to keep your elbows tucked in more, and really focus on the eccentric movement."
And I'm just thinking, "Sir, I'm pretty sure the full benefit for me is just not face-planting on the floor. My eccentric movement is my natural state, just trying to lift this ridiculously heavy five-pound weight." Honestly, the only advice I want at the gym is, "Are you done with that water fountain?"
And then there's the internet. Oh, the internet. It's a magical place, isn't it? Where you can learn anything, connect with anyone, and also find out that someone on TikTok believes their cat is receiving messages from outer space via interpretive dance. And then you spend twenty minutes watching it. Don't judge. It was compelling.
But my favorite internet phenomenon is the comments section. It's where optimism goes to die. You could post a video of a puppy saving a baby deer from a burning building, and someone would comment, "Probably staged. And that puppy's form is terrible. Also, why wasn't there a fire extinguisher?"
It's like people have forgotten how to just… enjoy things. My goal in life now is just to find joy in small, uncomplicated moments. Like when the Wi-Fi actually connects on the first try. Or when I remember where I put my keys before I have to leave the house. These are my victories.
So thank you tonight for being here, for sharing these small joys and absurdities with me. Now, if you'll excuse me, I hear the distant siren song of a churro cart, and my dream is calling. You've been a wonderful audience! Thank you!
I tried to get my life together, so I bought a smartwatch. Nothing says “I’m taking control” like strapping a tiny judgmental coach to your wrist. It buzzes every hour like, “Time to stand!” I’m like, “I’m on a bus.” It’s like, “Stand emotionally.”
It tracks everything. Sleep, stress, calories, my self-esteem. The other day it congratulated me for a “workout.” I was like, “What did I do?” It said: “You aggressively looked for your keys.” Great. Next week I’ll get a badge for “overthinking at 3 a.m.”
Notifications are out of control. My phone dings like I’m on call for a hospital, but it’s just my group chat: twenty adults sending thumbs-up reactions to a photo of soup. The group chat has subplots. One person’s mad, one person’s on vacation, someone’s dog has opinions. I miss when messages were simple. Now a single “K” can end a friendship.
Streaming services are the same. I have subscriptions to five platforms and somehow there’s still nothing to watch. They keep asking, “Are you still watching?” That’s rude. Don’t check in on me like that. If you care, ask how I’m sleeping. Ask if I’ve seen the sun. Don’t be like, “Hey, pal, still in those same sweatpants?” Yes. We’re a team.
Passwords have gotten ridiculous. Every site wants “eight characters, a capital letter, a number, a symbol, your childhood nickname, and the last four digits of a secret you’ve never told anyone.” Then it’s like, “This password is too weak.” Too weak? It’s stronger than me. I’m using that password to log into my feelings.
And two-factor authentication is a haunted house. I’m sitting at my laptop, it says it texted a code. My phone says it emailed the code. My email says it sent a push notification. My push notification says, “We noticed a suspicious login.” Yeah, it’s me! I look like this.
My mom texts like she’s defusing a bomb. She’ll send one sentence spread across twelve messages. “Hi.” “It’s me.” “Mom.” “Are you busy?” “Don’t worry.” “Everything’s fine.” “Call me.” That is not fine energy. Then she FaceTimes, camera under her chin, ceiling fan spinning like I’m being interrogated.
I tried meditating because everyone says it helps. I downloaded an app that yells at me to relax. Nothing like a British guy at 7 a.m. saying, “Let the thoughts pass like clouds,” while my mind is a tornado hitting a trampoline park. The app sent me a streak reminder. “You missed yesterday.” Oh cool, I’m failing at sitting still.
Self-checkout has turned us into unpaid employees. The machine is like, “Unexpected item in the bagging area.” Yeah, it’s my dignity. I love when it needs approval. I’m standing there holding broccoli like I got carded for vegetables. A teenager with a magic key wanders over like, “You trying to steal lettuce?” No, but ask me again and I might.
Dating apps feel like job interviews where no one has benefits. Every profile is a list of demands. “Be adventurous, love dogs, climb mountains.” Can we meet at a coffee shop and just be honest? “My hobbies are sitting and not climbing.” And stop asking for “someone who doesn’t take themselves too seriously.” You’re holding a fish in 80% of these photos. You are very serious about the fish.
Working from home gave us a new language. “You’re on mute.” “Can you see my screen?” “I think there’s a lag.” That’s not the internet—that’s my personality. I love when someone says, “Let’s take this offline,” and then schedules three more meetings to repeat the meeting we just had. My smartwatch is in the corner like, “Heart rate elevated.” Yeah, because I heard “circle back.”
Anyway, my watch says it’s time to stand. I’m going to consider that a full-body workout and reward myself with soup. I’ll send a photo to the group chat and we will never be free.
