10 Hilarious April Fool’s Pranks for the Office: My personal list of playful but safe office pranks that won't get you fired

One April morning a few years ago, I walked into the office to find my entire desk wrapped in aluminum foil — yes, even my stapler. At first, I groaned, but by the time I unwrapped my coffee mug, I couldn’t stop laughing. That day reminded me that a little humor can brighten even the most stressful workplace. Small spaces — whether it's a cozy kitchen or a cubicle — are perfect for sparking big creativity, and April Fool’s is the perfect excuse. So here are my 10 favorite office prank ideas, from my own playbook and those I’ve witnessed in the wild.

1. Keyboard Confusion

Rearrange a few keys on a colleague’s keyboard. It’s subtle, harmless, and creates just enough confusion to get a good laugh. Just make sure they’re not on a serious deadline.

2. The “Broken” Screen Saver

Take a screenshot of their desktop, set it as wallpaper, then hide their icons. It's low-effort but highly effective — almost as good as when I once used a room planner tool to prank a colleague by rearranging their virtual office layout overnight.

3. Voice Assistant Gone Rogue

If your office has smart speakers, change the wake word or set it to respond with something silly. Just be prepared for an all-day giggle fest.

4. Fake Zoom Background

Create a ridiculous custom background for someone’s video calls — maybe a beach scene with them photoshopped onto a lounge chair. You’d be surprised how many co-workers won’t notice at first glance.

5. Desk Swap

If two colleagues are game, swap everything on their desks — chair, monitors, even personal items. When they arrive, they’ll think they’re in the wrong spot. I once used a free floor plan creator to plan a desk swap down to the exact pen holder.

6. Elevator Surprise

Put small googly eyes on the elevator buttons. Everyone who steps in will crack a smile — though some might wonder who’s watching them.

7. Sticky Note Explosion

Cover a desk, monitor, and chair with sticky notes. Bonus points if you use different colors to create funky patterns or a secret message.

8. The “Upgraded” Mouse

Put a small piece of tape over the bottom sensor of a colleague’s mouse. It’s silly but totally safe, and the fix is obvious once they see it.

9. The Digital Makeover

For a tech twist, create a fake newsletter announcing a bizarre office policy. Just don’t let it run past noon — April Fool’s etiquette matters. You could even illustrate it like you’d set up a AI interior design render, adding fake “office upgrade” images.

10. Plant Takeover

Fill a coworker’s workspace with potted plants. Whether tiny succulents or giant ferns, they’ll be surrounded by green — and maybe secretly appreciate the fresher air.
