45 April Fools' Pranks for Work That Won't Get You Fired

Most April Fools’ lists were written for an office nobody works in any more. Half the team is remote, IT locks the laptops, and the prank that was funny in 2015 now reads as a security incident.

So here are 45 pranks sorted by what you actually have — five minutes or a whole evening, a shared office or a Zoom grid — plus the short list of pranks that end careers rather than meetings. Steal any of them verbatim.

Before you prank anyone: the three-question test

Every prank that has gone badly at work failed at least one of these. Run a candidate through all three before you commit.

1. Does it touch money, health, immigration status, or someone’s job? If yes, stop. There is no version of a fake layoff that lands.
2. Can the target undo it in under two minutes, alone, without IT? If undoing your prank needs a helpdesk ticket, you have not made a joke, you have made work.
3. Would it still be funny if the target were having the worst week of their life? You usually do not know. This is the one that catches pranks aimed at the wrong person.

A prank that passes all three can still flop. A prank that fails any of them is not a coin toss — it is a scheduled apology.

Five-minute desk pranks

For when you got in early and have until the first standup.

1. The sticky-note glacier. Cover every surface of a desk in one colour of sticky note — monitor, chair, keyboard, mug, stapler. One colour reads as deliberate; mixed colours just read as mess.
2. Everything rotated 90 degrees. Don’t hide anything. Turn every object on the desk a quarter-turn, including the monitor and the chair. It takes people a surprisingly long time to work out what is wrong.
3. The mouse’s blind eye. A small square of sticky note over the optical sensor. Unresponsive mouse, thirty seconds of confusion, instant fix once found.
4. Swapped keycaps. Pop two adjacent keys off and switch them. Two. Not the whole keyboard — that is a twenty-minute repair and a genuinely annoyed colleague.
5. The upside-down drawer. Open a desk drawer, lift out the tray of pens and clips, turn it 180 degrees, put it back. Everything is in the wrong place and nothing is missing.
6. A single wrong photo. Replace one framed desk photo with the same frame containing a picture of Nicolas Cage. The trick is doing exactly one, so it takes days to notice.
7. The phantom crumb. A realistic fake insect in a potted plant or on a keyboard tray. Keep it to one, and keep it away from anyone you know is squeamish.
8. Autocorrect sabotage. Add one text-replacement shortcut on an unlocked machine — “thanks” becomes “thanks, legend”. Harmless, and they will find it in the first email they send.
9. The chair at maximum height. Wind a colleague’s chair to its highest setting and put the back fully upright. Petty, reversible, effective.
10. Wrong-name mug. Swap their mug for an identical one with a slightly different name on it. Steve becomes Steven. Watch them not quite trust it.

Pranks worth setting an alarm for

These need the night before or a lunch break, and they are the ones people photograph.

11. The Jell-O stapler. The Halpert classic: suspend a stapler in a bowl of set gelatin. Make it the night before — gelatin needs about four hours — and bring it in cold.
12. Balloon flood. Fill an office, a cubicle, or the footwell under a desk with balloons. A helium tank is overkill; a bag of balloons and two people with lungs is about forty minutes.
13. Wrapping paper everything. Gift-wrap every item on a desk individually, including each pen. Foil wrap is faster than paper and looks more unhinged.
14. The office in miniature. Replace a desk’s contents with doll’s-house-sized versions — tiny stapler, tiny notebook, tiny plant. More work than it sounds, and funnier than it sounds.
15. Aluminium foil desk. Foil the entire workstation like a leftover casserole. Costs about four dollars and photographs better than anything else here.
16. A wall of the target’s own face. Print thirty copies of a colleague’s headshot from the company directory and tile them across their wall or the inside of their locker.
17. Chair swap chain. Move every chair in the room one desk clockwise. Nobody notices immediately, and then everybody notices at once.

Screen, keyboard and tech pranks

Lowest effort and highest hit rate — and the easiest category to take too far, so everything here is reversible in under a minute.

18. Language switcheroo. Change the display language on an unlocked machine. Pick one with a familiar alphabet so they can navigate back: Swedish, not Japanese.
19. The desktop screenshot. Screenshot their desktop, set it as the wallpaper, then hide the real icons. They will click on ghosts for a full minute.
20. Upside-down display. Ctrl+Alt+↓ flips the screen on Windows; Ctrl+Alt+↑ puts it back. Tell them the shortcut once they crack.
21. Cursor speed to maximum. Push mouse sensitivity to the top of the scale. The cursor becomes a startled bird.
22. The copier note. Slip a page reading “HELP — I’M TRAPPED IN THE COPIER” halfway down the paper tray, so it surfaces mid-afternoon for someone who has forgotten what day it is.
23. Reversed scroll. Invert scroll direction in system settings. Universally infuriating, instantly fixable, nothing at risk.
24. The very slow zoom. Increase browser zoom by 10% each time you walk past their desk. By 4pm the internet is enormous and they have no idea when it started.
25. Autoplay on the shared speaker. Queue a duck quacking on the meeting-room speaker at low volume. Twenty minutes of a room slowly investigating the ceiling.

Pranks that work on a video call

The genuinely underserved category — most prank lists still assume everyone shares a room. These are for the remote team half of the org chart.

26. The frozen-frame bit. Take a still of yourself looking attentive, set it as a virtual background, and go silent mid-sentence. Come back forty seconds later, mid-word.
27. Identical backgrounds. Get everyone except one person to use the same virtual background before the call starts. Say nothing about it.
28. Everyone as the boss. The whole team sets their virtual background to a photo of the meeting organiser’s face.
29. The mystery attendee. Rename yourself “Recording in progress” and join with your camera off. Watch the meeting become extremely professional.
30. Slow-motion mirroring. Copy one colleague’s gestures on a two-second delay for the whole call. Only works if the group is small enough to see everyone.
31. The name swap. Two people swap display names for the meeting and answer each other’s questions with total confidence.
32. A background that shrinks. Start with a normal room background and swap it every five minutes for the same room, further away, until you are a dot.
33. The unexplained hat. Wear an absurd hat and never once mention it. Deny the hat if asked. Some teams take an entire hour.

Slack and Teams pranks

34. Emoji-only day. Reply to every message in one channel using only emoji, all day, including in threads where it makes no sense.
35. The status commitment. Set your status to “In a meeting until 2027” and leave it there.
36. Custom emoji ambush. Add a custom emoji of a colleague’s face — with their permission — and get the channel to react with only that for a morning.
37. The recurring nonsense invite. Send a calendar invite for a weekly “Synergy Alignment Sync (Mandatory)” with an agenda of one item: “TBD”. Cancel it at 4pm.
38. Thread necromancy. Reply seriously to a message from eighteen months ago and let the notification do the work.
39. The fake typing indicator. Open a DM, type a long message, delete it, retype it, delete it. Do this for ten minutes. Say nothing. Devastating.

Coffee and kitchen pranks

The office kitchen is the one place remote and in-office teams both still care about.

40. The decaf switch. Swap the beans for decaf and say nothing until someone complains about being tired. The only prank here that improves with a full week of patience — and a fitting way to mark any coffee-adjacent occasion.
41. Salt in the sugar caddy. Ancient, still works, undone by one honest label. Put a note under the lid so only the first victim gets caught.
42. The wrapped fruit. Individually gift-wrap every banana in the fruit bowl.
43. Fake office-wide policy. A printed notice above the sink: “By order of Facilities, mugs must now be washed clockwise.” Sign it from a department that does not exist.
44. The impossible biscuit. Buy a tin of the good biscuits, refill it with the cheap ones, and leave it in the kitchen.
45. Ice-cube surprises. Freeze a plastic bug, a googly eye, or a tiny rubber duck into the office ice tray. Discovered one drink at a time, all afternoon.

The pranks that get people fired

Not a disclaimer — a list, because every one of these gets proposed somewhere each year.

• Fake layoffs, fake HR emails, fake resignations, including “hilarious” fake termination letters. This is the most common April Fools’ incident that ends up in front of a lawyer.
• Anything impersonating a real executive by email or message. That is not a prank, it is the shape of a phishing attack, and it will be logged as one.
• Fake security alerts, fake data breaches, fake fire alarms. People take the real ones less seriously afterwards.
• Anything involving someone’s visa, salary, benefits, or medical leave. No exceptions, and no context makes it fine.
• Pranks on someone who is new. They have no idea what is normal here yet, and no standing to object.
• Physical pranks that could actually hurt — rigged chairs, air horns near anyone’s head, anything on the stairs.

The reliable test: if the prank only works because the target genuinely believes something bad has happened to them, it is not a prank.

After the prank

Pranks make a great morning and a poor afternoon. They are a one-way performance — one person makes a joke and everyone else receives it — which is why the room goes flat around 2pm, and why they are a weak substitute for actual team building games or a proper icebreaker.

What keeps a team laughing for longer is the format where everybody is equally bad at the task. That is the whole mechanism behind a chef-led cooking class, a wine tasting where nobody can identify the grape, or a virtual happy hour built around making the drink rather than holding one. Nobody is the audience, so nobody has to be the target.

Run the pranks in the morning. Book the thing everyone does together for the afternoon — and if April is too far off, keep a few of these ideas for the next time morale needs a nudge that isn’t a meeting.
