The humble sticky note was a mistake. Specifically, an "accident" by 3M scientist Dr. Spencer Silver in 1968, who was trying to create a super-strong adhesive but ended up with something that barely held on. It’s poetic, really. The most temporary medium in history became our most permanent way of communicating everything from "don't eat my yogurt" to "the printer is possessed by a vengeful spirit." Honestly, funny post it notes messages are more than just scribbles; they’re the unsung artifacts of our collective sanity in a world of endless Zoom calls and spreadsheet fatigue.
We’ve all seen them. You walk into the breakroom and there’s a neon pink square stuck to the microwave. It doesn’t just say "Clean me." It says, "The microwave has been feeling neglected lately. It’s starting to think you only use it for its body (of heat)." It’s that specific brand of passive-aggressive-yet-whimsical humor that keeps a workplace from imploding.
The psychology of the sticky note saga
Why do we do it? Why not just send an email? Because an email is a chore. A Slack message is a notification that needs to be cleared. But a physical note? That’s tactile. It has personality. Dr. Nick Wigmore, a workplace psychologist, has often discussed how physical environments influence social dynamics. When you leave a note, you’re claiming space. You’re saying, "I was here, I have a sense of humor, and please for the love of everything holy, stop stealing my almond milk."
There’s a weird tension in office communication. We have to be professional, but we’re also human beings who are bored and caffeinated. This leads to the "Passive-Aggressive Note War" phenomenon. You’ve probably seen the viral photos of the "Dave" saga. Someone leaves a note: "Please don't eat Dave's lunch." Within an hour, there are ten more notes. "I am Dave's lunch. Help me." "I ate Dave's lunch and it was delicious. Signed, Not Dave." It’s basically the 20th-century version of a Reddit thread, played out on a refrigerator door.
The effectiveness of funny post it notes messages lies in the "pattern interrupt." Our brains are wired to ignore standard signs. "Employees must wash hands" is white noise. But a note over the sink that says, "Wash your hands like you just finished cutting jalapeños and you’re about to take out your contact lenses"? You’re going to scrub. You’re going to remember that. It sticks—literally and figuratively.
When the 3x3 square becomes high art
It’s not just about the text. It’s about the delivery. People have gotten incredibly creative with how they use these little squares. Take the "Post-it War" of 2016 in New York City. It started with a simple "HI" in a window on Canal Street and exploded into massive, multi-story murals of superheroes and cartoons made entirely of sticky notes. It was a massive waste of billable hours, sure, but it was also a beautiful display of human connection in a city known for being cold.

The fridge is the frontline
The office refrigerator is the most contested territory in the modern world. It’s where the most legendary funny post it notes messages are born.
- The "Exorcist" approach: Sticking a note on a Tupperware that says, "Property of the CDC. Do not open without Hazmat suit."
- The "Parenting" approach: "I’m not mad that you took my soda, I’m just disappointed. We talked about this, Kevin."
- The "Existential" approach: A note on a single, lonely grape that reads, "Help, my brothers are all gone. I am the last of my kind."
But let's be real—it’s not always about jokes. Sometimes, it’s about survival. In high-stress environments like hospitals or kitchens, these notes are shorthand for "I’m losing my mind, let’s laugh for three seconds." Research by the Mayo Clinic has shown that brief moments of humor can actually lower cortisol levels and improve team cohesion. So, that "Don't touch the thermostat" note with a drawing of a shivering penguin isn't just a memo. It's a health intervention.
The etiquette of being hilarious (and not getting fired)
There is a fine line between "the funny guy" and "the guy HR wants to talk to." You have to know your audience. A note that works in a startup might get you a stern talking-to in a law firm. Tone is incredibly hard to convey in three square inches of paper.
Keep it punchy.
If your note is a paragraph, you’ve failed. The best notes are 10 words or fewer. "If you finish the coffee, a kitten loses its wings." Simple. Dark. Effective.
Avoid the "Reply All" of sticky notes.
Don't be the person who puts a note on every single item in the office. If everything is a joke, nothing is a joke. Use them sparingly. Like a fine spice or a well-timed "that's what she said."

The "Debbie" Factor.
We all know a Debbie. Or a Steve. The person who takes things literally. If you put a note on a printer saying, "This printer only responds to compliments," and Debbie spends twenty minutes telling the HP LaserJet that its paper tray looks slim today... well, that’s actually hilarious, but you might feel a little guilty. Maybe.
Beyond the office: Sticky notes in the wild
We shouldn't ignore the "Home Edition" of funny post it notes messages. Couples use them as a low-stakes way to communicate chores without it feeling like a lecture. "The dishes are lonely. They missed you today." It’s much harder to get mad at a talking pile of laundry than a nagging text message.
Even in the world of tech, these analog tools persist. Software developers use them for "Kanban boards," moving tasks from "To Do" to "Done." But even there, humor creeps in. I’ve seen boards where the "Blocked" column is renamed "The Pit of Despair" or "Where Dreams Go to Die." It’s a way of acknowledging the grind while maintaining a bit of distance from it.
Common Misconceptions
A lot of people think the yellow ones are the only "official" ones. Incorrect. The neon green ones are for warnings. The bright pink ones are for emergencies (or "I ate your cake"). The blue ones? Nobody knows what the blue ones are for. They’re like the "U" in "color"—some people use them, but it feels a bit fancy and unnecessary.
Another myth is that digital versions are just as good. They aren't. A digital "sticky note" on your desktop is just another thing to click away. You can’t stick a digital note to someone's back. You can’t leave a digital note inside a coworker's notebook to surprise them three weeks later during a meeting with the CEO.

Why we need this brand of chaos
The world is increasingly digitized and sanitized. We spend our lives in "clean" interfaces. The messy, handwritten, slightly crooked sticky note is a rebellion. It’s a reminder that there’s a person behind the screen. When you see funny post it notes messages, you’re seeing someone’s handwriting—the way they loop their 'g's or how they ran out of space and had to write the last three letters vertically down the side.
It’s human. It’s imperfect. It’s usually a little bit snarky.
If you’re looking to inject a bit of this into your own life, start small. Don't go for the "viral" joke. Just look for a situation that’s slightly annoying and add a bit of levity. Instead of "Out of Order," try "Having a mid-life crisis. Please check back when I’ve found myself." It changes the energy of the room. It turns a frustration into a shared moment of "yeah, I get that."
How to execute the perfect sticky note "Prank"
If you’re ready to graduate from simple messages to actual fun, here is a breakdown of how to handle it without being a nuisance.
- The "Hidden Audience": Place a note where only one specific person will find it. Under a computer mouse is a classic. "I see you." Or, "Stop clicking me so hard, it hurts."
- The "Slow Burn": Change the note slightly every day. If you have a plant in the office, put a note that says "I'm thirsty." The next day: "I can taste colors now." The third day: "I require a sacrifice."
- The "Animate Object" Trick: Put googly eyes on the stapler and a note that says, "I've seen things you people wouldn't believe."
Actionable insights for your desk
If you want to master the art of the sticky note, keep these three things in mind:
- Contrast is King: Use a dark Sharpie on a light note. If they can’t read it from three feet away, the comedic timing is lost.
- The Power of the Drawing: You don't have to be Da Vinci. A simple frowny face or a stick figure dramatically fainting adds 50% more "funny" to any message.
- Own the Medium: Don't apologize for the note. If you're going to be the person who leaves funny post it notes messages, do it with confidence.
The next time you're frustrated with a jammed copier or a messy kitchen, don't send a stern email to the "All Staff" list. Grab a pad of 3x3 paper. Find a pen that actually works. Think of something slightly absurd. Stick it, walk away, and wait for the first person to walk by and snicker. You’ve just made the office 1% more tolerable, and honestly, that’s more than most meetings accomplish.
Next Steps for Your Office Humor:
- Identify a "Pain Point": Look for a common office annoyance (the slow elevator, the empty water cooler).
- Draft a One-Liner: Think of a way to personify the object.
- Deploy and Observe: Place the note and see if it sparks a "note war." If it does, you’ve successfully boosted office morale.
