20 Harmless April Fool's Day Pranks for the Office

The best April Fools pranks for office teams are light and kind. A good office prank is like a good team lunch: quick, shared and everyone feels better afterwards. These April Fool's pranks for the office follow three rules:

1. Never mess with real work. No deleting files, changing passwords or touching anything a client could see.
2. Pick colleagues who enjoy a laugh. Skip the person on a deadline.
3. Undo it within minutes and own up with a smile.

Desk and computer pranks

1. The swapped mouse receivers. Swap the USB receivers of two identical wireless mice. Each person's cursor now moves when the other person moves their mouse. Reveal quickly.

2. The desktop screenshot. Take a screenshot of a colleague's desktop, set it as the wallpaper and hide the real icons. Nothing clicks.

3. Tape under the mouse. A small piece of opaque tape under the sensor, with a sticky note saying "April Fool!" underneath.

4. Upside-down screen. On many Windows PCs, display settings allow the screen to be rotated. It works best during a chai break.

5. Autocorrect surprise. In their personal phone's text replacement (with permission from a friend who's in on it), make "ok" turn into "okie dokie artichokie".

6. Fake broken screen wallpaper. Classic, safe and easy to undo.

7. Colourful keyboard. Cover the tops of random keys with small coloured stickers. Leave the letters visible.

Around the office

8. Googly eyes everywhere. Printer, water cooler, coffee machine, the plant.

9. Bubble wrap welcome. Bubble wrap under the doormat or desk chair mat.

10. Coffee cup swap. Swap two people's identical mugs. Only if they drink the same thing.

11. Sticky-note art. Turn a monitor into pixel art with sticky notes.

12. "Voice-activated" printer. Put a sign on the printer saying it now works by voice command. Watch people politely asking it to print.

13. Fake insects. A rubber cockroach in the pen holder. Skip if someone has a real phobia.

14. Chair height shuffle. Raise a colleague's chair by one notch every time they get up.

15. The confetti drawer. A handful of paper confetti in a drawer they open daily.

16. Desk in foil. Wrap small desk items (stapler, pen holder, mouse) in aluminium foil. Takes a while, but always gets a laugh.

Team-wide pranks

17. The fake memo. An "official" email announcing the office is now a "silent Monday" zone, or that all meetings must be held standing on one leg. Make it obviously ridiculous and send it to people who know.

18. Out-of-office everywhere. Everybody sets a one-hour joke OOO: "Away chasing the escaped office plant."

19. The donut box. A donut box filled with vegetable sticks. Have real donuts ready as the payoff.

20. Team photo swap. Swap everyone's desk photos with printouts of the same celebrity.

The reveal

Every prank should end with a laugh and a quick clean-up. For something low-effort in the team chat, a few April Fool's jokes do the trick.

Frequently asked questions

Are office pranks a good idea?

Light, harmless pranks can be great for team spirit. Workplace culture matters: never touch anyone's work files or security settings, and stay away from anything involving customers.
