16 Terrible Computer Pranks That Could Get You Fired

Look, you're an adult human being. You're better than this. Don't do any of the things in this slideshow.

Just because it’s April Fool’s…
Just because it’s April Fool’s…

I know, I know – that jerk from sales deserves it. That snippy attitude last time you showed up to fix his “slowdown problem,” which was obviously just him having like 150 Chrome windows open at once. Still, as tempting as it might be, you can’t just take revenge on the guy’s computer. Please, just go and read something else now. You’ll feel like a better person.

Ctrl+Alt+arrow keys

This is a simple little trick that flips the screen orientation in the direction you push – Ctrl+Alt+up arrow returns everything to normal. Surprisingly few people know about this.

CRUELTY INDEX: 1/10

FIRED?: I can’t imagine why, though bear in mind that some people have absolutely no sense of humor.

Shift+Alt+Print screen
Shift+Alt+Print screen

Another handy, but little-known keyboard shortcut activates high-contrast mode for people with limited visual acuity – it’ll certainly confuse unsuspecting co-workers, though. Same keystroke fixes it.

CRUELTY INDEX: 1.5/10

FIRED?: Probably not.

Hey, your screen broke!
Hey, your screen broke!

Setting a picture like this as the background, then hiding the desktop icons and task bar, really does make it look like something has gone horribly wrong with the screen.

CRUELTY INDEX: 2/10

FIRED?: Souldn’t be.

Lots of input gags
Lots of input gags

Surreptitiously plugging a wireless mouse into someone’s computer and subtly moving their cursor around can be hours of fun, as can switching their keyboard layout to Dvorak. Changing autocorrect entries in Microsoft Word is also a time-honored favorite of the digital jerk.

CRUELTY INDEX: on average, 3/10, higher for extensive autocorrect malfeasance.

FIRED?: Probably not, although this is really frustrating if you don’t know what’s going on.

Screenshotting their desktop
Screenshotting their desktop

Another of the oldest tricks in the book is taking a screenshot of the victim’s desktop, setting it as their background, then hiding the desktop icons and taskbar. Cruel, though hardly unusual, and easy to fix. Bonus points if you gather up the desktop icons into a folder somewhere, rather than simply unchecking “display desktop icons,” by the way.

CRUELTY INDEX: 3/10, raised to 5/10 if you do this to particularly technophobic victims.

FIRED?: Nah.

Shock images/sites
Shock images/sites

There are a number of infamous shock images floating around the Internet, showing particularly graphic sexual or gory content. Replacing desktop backgrounds or browser bookmarks can be a shock to the unsuspecting. And no, I am not linking you to any of them here. Pollute your own search history.

CRUELTY INDEX: 5.5/10

FIRED?: Very possibly.

Fake BSOD

Yes, it’s another desktop background gag, but a particularly panic-inducing one. Although it might just be sort of confusing if you did it to someone with a Mac.

CRUELTY INDEX: 3.5/10

FIRED?: Probably not.

Adult entertainment

Various versions of “redirecting your co-worker to a porn site” or “placing fake porn on your co-workers desktop” have been around forever. Really, though, you could’ve been more creative.

CRUELTY INDEX: 5/10

FIRED?: Yeah, very possible. Or you could get your co-worker fired, you horrible jerk.

Task Scheduler fun
Task Scheduler fun

The Task Scheduler has a handy-dandy wizard function, which offers you an easy way to make a whole bunch of random crap happen on your victim’s computer, like web pages popping open and programs running seemingly at random.

CRUELTY INDEX: Varies – you can do a LOT with the Task Scheduler.

FIRED?: Depends on what you do.

The fact that you can set custom a.m./p.m. icons in the clock menu makes it possible to send various messages to your victim via the bottom-right corner of their screen.

CRUELTY INDEX: 1.5/10

FIRED?: Probably not.

AutoHotkey
AutoHotkey

Like the Task Scheduler, this innocuous little app is an enormously powerful toolkit for all sorts of obnoxious pranks. All you need to do is put together a custom script and get the victim to run it on his machine, and you can induce screen flickers, random beeps, play specific YouTube videos…

CRUELTY INDEX: Variable, but potentially very, very high

FIRED?: Again, depends on what you do.

URL shorteners, deceptive descriptions – whatever it takes. Never gonna give this video up.

CRUELTY INDEX: -5/10. Rick Astley is great.

FIRED?: Hell, you’ll probably get promoted.

Chorus!
Chorus!

Cutting up a song into individual instrumental or vocal parts, and then scripting them to play individually, at the same time, on separate computers, is, frankly, an impressive achievement. (H/T: Redditor hootorama)

CRUELTY INDEX: 1/10

FIRED?: Probably not, but it’s possible. A lot depends on the song you pick, I would expect.

Your computer is constantly hanging
Your computer is constantly hanging

It’s a simple, subtle little change that is nevertheless highly effective – swapping the normal cursor icon for the “busy” one, so that the victim’s computer always appears to be mired in a slowdown.

CRUELTY INDEX: It’s the little things that get you – I say 5/10 because this would drive me insane, but your mileage may vary.

FIRED?: If I had my way, yes.

That’ll teach you to leave all-caps on next time you reply-all to a big group email.

CRUELTY INDEX: 3/10, 1/10 if they really deserve it.

FIRED?: Guessing not.
