When I saw this contest, I knew I had to enter!  But which prank?  I have over the years witnessed and participated and researched thousands of pranks, from the simple to the extreme.  In my humble opinion, a good prank can be set up and excecuted quickly and effectively.  Sure, it would be funny to wallpaper someone's office with post-it notes, or fill their cubicle with packing peanuts, but who has the time or resources for that?  My favorite prank is the one where nobody is hurt or overly humiliated, and that everyone can enjoy a good laugh afterward.  I realized I couldn't narrow it down to just one.  Therefore, I am submitting my compilation of low-tech easy office pranks that are sure to annoy.  The computer based ones are factored off of Windows XP, and any other software may not work or require different steps.  Enjoy!

Step 1: Prank 1: the Impossible Desktop

This one is amazing in it's simplicity to execute and the results it yields.  If you have access to your targets computer, it can be pulled off in about 1 minute if you're quick.  Here's how it goes down:

Step 1: From the regular desktop screen of the computer, press the "PrtScn" button on the keyboard.  This takes a snapshot, or screenprint, of what is on the screen at that moment.

Step 2:  Open Paint (Start > Accessories) and either select Edit > Paste, or press Ctrl + V to paste the screenshot into Paint.  Then choose File>Save As and call it anything, but change the file type to .jpg, and save it to the Desktop.

Step 3:  Close out of Paint, and back on the desktop, Right Click and create a new folder, of any name.  Set it to one edge.  Any icon on the desktop that doesn' t have a white square with an arrow is an actual file or program, and can be moved into this folder.  The rest are icons, which once you move into the folder need to be deleted off the desktop.  You can remove everything from the screen EXCEPT the Recycle Bin.

Step 4:  Right click on the Start/Taskbar, and uncheck "Lock the Taskbar" if it is checked.  Now, if you put your mouse over the top edge of the Start/Taskbar it'll turn into a double ended arrow.  Drag it down until there is no Start/Taskbar on the screen.

Step 5:  To finish up, right click on the now empty desktop, and set the screenprint picture you took to be the wallpaper and walk away.

The Result:  Your target will not suspect anything is wrong with their computer until they go to click on something.  Anything really.  The only responding icon on the desktop now is the Recycle Bin (if they try to move it, they may figure you out, but who ever messes with the Recycle Bin?).  Once you've had your laugh, and maybe taken a video, undo your damage before your mark loses it.

Step 2: Prank 2: the Missing Desktop

This one requires a little more time and equipment than the first, but the effect can be similarily hilarious.  You will need a digital camera, and the abilty to temporarily move the monitor of the mark.  This works best for desktops.

Step 1:  Being careful to disturb as little of the surrounding area as possible, move the targets monitor from it's normal resting location.  Getting as many of the monitor cords out of the shot as possible, take a picture of the wall/area behind where the monitor normally is positioned.  Save this file to the target computer, and replace the monitor.

Step 2:  You will follow essentially the same steps as from the first prank, however using this picture you took as the background.  It may take a couple of tries to get it right. 

The Effect:  The final effect is what appears to be a hollow monitor with a Recycle Bin icon floating on it.  Of course, the illusion is broken if they move the monitor, or when they will inevitably rock side to side to witness the effect from different angles.

Step 3: Prank 3: the Mistyped/MadLibs Word Document

This one is great for individuals that commonly type or create documents, and even better for those that type but don't look at their screen while typing, but can be hilarious in any event.

Step 1:  Determine the software you will be making the adjustments in.  The following steps are outlined for Word 2007.  You may need to do a google search for "autocorrect ______" if using a different application.

Step 2:  Click the Office button,  Select Word Options, Click Proofing in the left pane, Click the AutoCorrect Options button, Select the AutoCorrect tab.  In the box labeld Replace, put a word or name (ideally one that will be typed often) and in the box labeled With, put a hilarious substitute.  Click Add, and you're done.  You may do this for multiple words, but 1 or 2 make it funniest.  For example, set it to replace the word "customer" with the word "buttnugget", or a common last name (like the boss) with "Dog-Breath"

The Result:  Once programmed, any time the replace word is typed into the document, it will automatically replace it with the work you typed.  This can have a MadLibs-like effect if you do many replacements, but otherwise may be overlooked unless your mark is a careful proofreader.  To ensure no one gets in trouble, I would pretend to proofread over their shoulder the first time they are typing and point it out, like, "Did you mean to refer to the user as a buttnugget?"  You can delete the rule from the Autocorrect settings.

Step 4: Prank 4: What's Wrong With This Stupid Computer?

This one is by far one of the most devious I have come across.  I imagine that IT professionals will curse the day this was discovered, as I can only imagine how many unnecessary tickets and frustrated calls this generates.

Step 1:  On the desktop, right click and choose "Create a shortcut".

Step 2:  Type the following:  shutdown -s -f -r -t 0 -c "message"   where "message" is anything you may want the computer to tell the individual as it's being shut down, such as "Virus Detected, Shut Down Initiated".  You have 127 characters max, and the quotation marks are required.  You may also delete that last section if you want it to seem normal (the entire -c "message" part.

Step 3:  Give it the name of a common program (like Internet Explorer) and hit OK to save your shortcut.  Now, that icon isn't fooling anyone, so right click it and choose properties.  Click on Change Icon, click the Browse button, and point it to C:\Program Files\Internet Explorer and chose iexplorer.exe to get a more appropriate list of icon choices.  Choose the appropriate one, hit Ok twice, and now you're set.  Delete their existing shortcut to Internet Explorer for good measure, and place your icon in it's place.

The Result:  Your mark tries to open Internet explorer, only to find their computer shutting down.  If you placed a message in the -c "message" portion, you can increase the hilarity by referencing virus or maybe something personal, like "Goodbye Bob...."

Step 5: Prank 5: Mouse Gone Mad

This one is classic but still fun.

Step 1:  Most modern offices use laser mice.  If yours still uses the roller ball kind, after applying for a job somewhere in the 20th century, you can follow these directions or simply remove the ball.  For everyone else, apply a piece of clear scotch tape to the underside of the mouse, covering the laser.

Step 2:  Using a Sharpie or other marker, color the area of the tape that the laser passes through.  Pretty much it, but most people will bang their mouse on the table top for several minutes before looking underneath.

Step 6: Prank 6: the Hunt-and-Peckers Keyboard Switch

As indicated by the title, this prank will only work for those people who have yet to learn how to type and still have to physically hunt and peck their way through text.  It's great fun.

Step 1:  Many IBM computer keyboards allow the keys to be popped off and re-attached using something thin and flat like a knife blade or flat-head screwdriver.  Test the feasibility of this prank on a key of small importance, like the Pause/Break key first, to ensure they indeed pop off and can be snapped back into place before proceeding.

Step 2:  There are several ways to go.  The best in my opinion is to make very small, subtle changes to the keyboard layout.  Swap the positions of the M and N keys for example, or E and R keys.  If you go too crazy, they are likely to notice.  Of course, you may want to do just that, putting words or phrases on their keyboard.  If you have access to other keyboards of identical make, you can acquire extra letters for repeats and longer phrases.  When they go back to proofread, they will be flabbergasted, and may even have a difficult time correcting the mistake if they indeed don't know the keyboard layout.

Step 7: Prank 7: "Who's Been Sitting in My Chair?"

If your office is anything like mine, the chairs tend to be multi-adjustable for height or recline comfort.  Here's a couple of ideas for keeping your co-workers on their toes.

Step 1:  If the chair has a switch that controls the recline lock (in one position, the chair leans back and forth, in the other the chair is locked into an upright position), change it.  When they sit down, they will either swing way back, or hit the back expecting to recline but don't.

Step 2:  If the chair has a height adjustable lever, you might be able to use string or a pencil or other method of wedging this lever up, so the chair sits as maximum height.  Sitting on the chair results in an immediate drop toward the floor.

Step 3:  One office I worked in had chairs that were tilt adjustable, but the default was to tilt forward.  You would raise the lever, adjust it back to the desired tilt, and then press the lever down to lock.  We affectionately called this the "eject button".  Anyone caught sleeping during trainings or meetings was subject to have an individual gently knock the lever up with their foot, throwing the target into the table or pitching forward.  Same could be used for people that sit on the front edge of the chair.

Step 8: Prank 8: I Believe You Have My Stapler...

This one actually results in destruction of property, so attempt at your own risk.

Step 1:  Acquire your targets stapler, preferably by stealth.

Step 2:  Pull up on the top to open the loading chute, and remove the staples.

Step 3:  While the stapler is still open, if you compress the top half, you will see that a thin blade of metal is exposed.  This is what actually forces the next staple through the paper.  Use a pair of needle nosed pliers or other pliers with a cutting edge to cleanly snip this blade off.

Step 4:  Replace staples, close, and replace stapler.

The Result:  Without the blade, there is nothing to force the next staple out of the stapler.  The mark will likely remove and replace the staples several times thinking it is jammed, and likely will never realize that their stapler is now worthless.  To protect your job, you may wish to buy a similar stapler (my office gets the standard ones from Office Max), modify it, and then swap with your target so you are not destoying company property.

Step 9: Prank 9: That Last Level Is a Fright....

If you haven't played the Scary Maze Game or it's sequel, you are deffinately missing out.  If your co workers haven't played it, well, don't pull this one on the elderly or anyone with a weak heart....

Step 1:  You can reach the game from numerous links, such as http://www.kensavage.com/archives/scary-maze-game/.  This page also has a great feature of code you can add to your own page that may not make the result as obvious.  There's also a link to the sequel, and the code for it as well.

Step 2:  Basically, refer someone unfamiliar with the game to play.  If they struggle too much, as a secret/help, if you click and hold your left mouse button, you can then go directly to the Red area and release to achieve the next level.

The Result:  Well, I can't type it as well as this video shows it: http://www.youtube.com/watch?v=j0qBGSnVqeo&feature=related

Step 10: Prank 10: Diet Soda Bath

Ok, this one deviates a bit from my 'harmless' section, but it is so ingenious I couldn't pass up including it.  Besides, I couldn't stop at 9 pranks could I?  I think not!  If you have a group fridge, and have a lunch/drink thief in the midst, even better!!

Step 1:  You will need a 2 liter or 20 ounce bottle of Diet soda.  You can try it with regular to widen your potential target pool, but diet by far has the best reaction.  You will also need a Mentos candy, needle and thread, and hammer.  This is best prepared (mostly) ahead of time for maximum effect.

Step 2:  Take the needle and thread and using the hammer, pass a threaded needle through the center of the mentos candy.  The hammer will help drive it through the tough candy shell.  You could also use something small and more rigid than a needle to make the hole first, like a paper clip, and eliminate the need for the hammer at all.

Step 3:  If you are very careful (and maybe have some help to pry up on the plastic ring while opening), it is possible to unscrew the cap from a soda bottle without breaking off the small ring that indicates it's been opened.  If you don't/can't manage it, you can seperately pry the ring off and discard completely, or use a couple of dots of superglue to reattach it when the cap is back on.  The idea is, you don't want the person opening the bottle to realize it's already been opened.

Step 4:  Pour a small amount of soda out of the bottle to give more air space and improve the likelihood of success.  Place the Mentos candy just inside the DRY mouth of the bottle, and reattach the cap.  Use the thread to keep the candy at the very opening of the bottle.  When the cap is reattached, the plastic bottle threads will grab and hold the thread positioning your candy , and the cap itself will hide the presence of the candy.

Step 5:  Trying to avoid sloshing soda all around the bottle, position it within the company fridge or give to your unsuspecting coworker, and quickly duck away.

The Result:  Yeah, you saw that video of theguys making the diet Coke fountains with Mentos, right?  Same concept.  Bottle is opened, the threads holding the candy are freed, the candy falls into waiting soda below, person hoding bottle (and nearby victims) will likely need a change of clothes unless the reflexes are VERY fast.  That fridge thief?  Yeah, not a mystery any longer...

Step 11: Summary...

The previous are my offerings for the prank loving community at large.  The only one of these I believe is original is the stapler prank.  All others I have heard of or read about elsewhere on the net, over the course of years.  As office life is dull and boring, I hope to spice up your April 1st  antics.  Not only do I not take credit for most of these pranks, I also do not take responsibility for your actions, the reactions of others, slashed tires or angry mob hunts you may receive, nor any impact to your employment status for using these.  Most are harmless, except 7 could cause injury, 8 damages property, 9 may give someone a heart attack, and 10 may stain someone's clothing.  But, that's why they are last and not first.  Have fun!
<p>Reading this article already made me smile and a laugh inside of me. I can't wait to do this to my co-worker.</p><p>http://cheapgadgetsstore.com/work-station/ </p>

<p>Hahaha! I'm totally going to do this to someone I work with.</p>
One more for the computer prank list: KeyPrank.com
<p>This place is awesome ^_^ I got high and reading stuff from here is just messing me up :D Also this site here is pretty nice http://my-funny-jokes.com/ :D :D :D :3 </p>
<p>Sorry if this is stupid but what is the &quot;scary maze game&quot;?</p>
The link I used might be dead, but essentially it's a simple maze game that when finished, flashes a scary picture and plays a horrific scream. If you Google &quot;scary maze game&quot; I'm sure it's easy to find a current link that works :-)
<p>This Miley Wrecking Ball Doll prank would be a great addition to this list! It's not an old classic one but gets points for trending pop culture. http://allinwebpro.com/wrecking-ball-office-doll/ </p>
A lazy co-worker finally found his telephone mouthpiece had a very tiny piece of clear tape over the microphone hole, but only after he was forced to shout into his phone for days. The pranksters giggled with every word. <br> <br>The soda pop trick sounds messy, but there are nasty laws about food tampering that could get the cops involved.
&nbsp;Cool! &nbsp; Heh heh heh.... &nbsp;actually that's a cool desktop even for myself...
yep<br />
If they have a laptop, just close the lid and then take a picture.
&quot;Regular&quot; cola won't work; they tried it on Mythbusters. It's something in the Diet Coke that reacts with the Mentos. <br />
<p>It's the artifital sweetener in the Diet Coke and nucleation cites in the mentos<em>.</em></p>
&nbsp;Wow! &nbsp;Great list!
You don't need both -r and -s commands. Keep -r if you want the computer to restart or -s if you want it to shutdown. This is pretty funny. I've had the shortcut link to something else such as paint or solitaire, but I never thought of using the shutdown command. Good work.<br />
A simpler way to do this is to just right-click the desktop, go to the View -&gt; menu, and uncheck Show Desktop Icons. Then set the wallpaper as you said.<br />
hey, I&nbsp;never knew you could do that! muhahahahahahaha!!!!!1!!!!<br />
also, you should make it so the task bar auto hides so even that is useless<br />
After submitting, I&nbsp;thought of another favorite, but am unsure if I&nbsp;can/should ammend my submission for the contest.&nbsp; Take a glass (clear is best so you can see what is inside), fill it with any liquid (ice water, soda, etc).&nbsp; Place an index card or piece of cardstock over the top of the glass, and invert it onto vicim's desk or table.&nbsp; While holding the cup in place, carefully slide the card out from what is now the bottom.&nbsp; The liquid will form a seal, and air pressure keeps it from spilling unless that seal is broken.&nbsp; If you are VERY careful and quick, you can re-slide another card underneath the cup with a minimal of mess.&nbsp; Otherwise, there is virtually no way to righten the cup without all the contents spilling out all over the table/desk.&nbsp; I've known people to do this at restaurants to the waitress if there is not a cloth tablecloth and they had very bad service, but I personally would just leave a very low tip (low tip is worse than no tip, cause no tip means you might have forgotten.&nbsp; A low tip, like $0.25 means you deliberately underpaid).
I'd like to add an easy one to this list.&nbsp; For Windows users, try the key combination CTRL+ALT+(arrow key) where the arrow key is your desired desktop orientation/direction.<br /> <br /> So try CTRL+ALT+(DOWN/LEFT/RIGHT) to make things more interesting.&nbsp; (CTRL+ALT+UP will correct it.)<br /> <br /> This is a simple, harmless and completely reversible prank to pull on those IT co-workers who ought to know better to lock their console when they walk away from their desk!<br /> <br /> Side-note:&nbsp; If you have multiple monitors, this key combo only changes the orientation of the display where your mouse cursor resides, so if you want to turn primary &amp; secondary upside down, you'll have to do the key combo once for each.<br />
what does it do?
On computers whose video cards support screen orientation, that combination rotates the screen 90, 180, or 270 degrees.&nbsp; The Ctrl+Shift+Up corrects, or sets the orientation back to normal settings.
At work, our computers use an Intel graphics card, and if we open the Intel graphics controller icon in the system tray and enable screen rotation, that trick indeed is great.&nbsp; We have a very strict policy on locking workstations when you walk away from them, and that is a favorite, along with emailing the boss saying &quot;I quit&quot; from that person's email account.&nbsp;&nbsp;I&nbsp;didn't include it, because it doesn't seem to work on every computer, mine at home for instance does not rotate with those commands.&nbsp; After further research, I&nbsp;found that the screen rotation is display adapter determined, not all possessing the ability.&nbsp; To check, you can go to Control Panel&gt;Display&gt;Settings&gt;Advanced button and look for an Orientation tab to see if your video card will support screen rotation.
