Alright, good evening everybody! How are we all doing tonight? Yeah? Yeah? nobody's gonna say 'bad'? Ok, fair enough.

You know, I was walking down the street the other day, and I saw this sign outside a shop that said, "Wet Paint." I thought, "Well, that's weird. Isn't paint supposed to be wet? When's the last time you saw a bucket of dry paint? That's like saying 'Wet Water' or 'Hot Coffee' – oh, wait, they do say that last one. Never mind.

And what's the deal with self-checkout machines? They always tell you, "Unexpected item in bagging area." Really? It's a bag of chips, not a flamingo doing the tango! And why is it always an "unexpected" item? You know what would be an unexpected item? If I scanned a live bear through there. "Oh, hey, just picking up a loaf of bread, some milk, and THIS GUY!"

You ever notice how people get real testy about their favorite coffee places? "Oh, you go to Starbucks? You monster! You know they burn their beans, right?" Yeah, well, you drink tea, so you're basically a serial killer. And why is decaf even a thing? People who drink decaf are like vegetarians at a steakhouse – sure, you can have a seat, but why are you even here?

And speaking of coffee shops, what's with the sizes? Small, medium, large – that's simple, right? But no, we've got "tall," "grande," "venti"... I stand in line, and I'm like, "Uh, yeah, can I get a... medium-ish? Just whatever comes between 'not enough' and 'that's too much, are you crazy?'"

You know who I feel bad for? Meteorologists. They're the only people who can be wrong 90% of the time and still keep their jobs. "There's a 50% chance of rain tomorrow." Yeah, and there's a 50% chance I'm gonna wear pants tomorrow, but you don't see me on the news talking about it!

Alright, that's my time. You've been a great audience! Remember to tip your waitresses, try the veal, and... nah, I can't even say that with a straight face. Goodnight, everybody!

Absolutely! Here's a 3-minute stand-up routine with no puns—just observational and relatable humor:

You ever try to get healthy, but your body's like, "Whoa, whoa... calm down, superhero." I joined a gym—first time walking in, the treadmill looked at me like, "We both know you're here for the wifi." They hand me a to wel and I'm like, "Oh, I'm not gonna work up enough sweat to justify this, but thanks for believing in me." I try eating salads. I don't understand people who say salads fill them up. I finish a salad and immediately want to reward myself—with a pizza. The salad's just the job interview, the pizza's what brings me real joy . That's why my salad always comes with a side of fries. My body's like, "You remember vegetables, right? In troduce them to their friend, carbohydrates."

Ordering food is hard. Restaurants make everything so customizable now. "Do you want that grilled or fried? Pick your bun, pick your sauce, choose your mood for the day." By the time I'm done I feel like I've taken t he SATs. And that's before they ask about up-sizing. "Would you like to upsize for just a dollar?" I always say no—because I'll pay twice that much in guilt.

Dating apps are even worse. Your thumbs do more cardio than your legs. Swiping is the new stairmaster. Profi les always say, "Love to travel!" I match with you, you mean going to Target in a different zip code. Why do we act like flying to Portugal is our hobby? Meanwhile, my idea of exploration is getting up to find the re mote.

I tried meditating because they say it's good for stress. My head is full of thoughts. The app says, "Let yo ur thoughts float by like clouds..." Suddenly all my clouds are bills. Student loans, dental bills—I'm basical ly in a storm.

And then there's technology. My smart watch knows I've been sitting for too long. Every hour, it vibrates, " Time to move!" It's like a parole officer living on my wrist. I miss the days when only my conscience judged me for lying on the couch. Now I have a device, "You've walked 32 steps today... are you...are you okay?"

But in the end, I'm trying! One salad at a time. One step. One dating profile. And sometimes, one slice of p izza. Because let's be honest—no one ever had a life-changing moment during a salad.

Thank you, everybody!
