In every office, there's the guy who has no sense of humor and hates the idea of having fun. If you're that guy, you should probably stop reading this now.

Still with me? Good. You see, the thing is, seriousness is overrated. Sure, there's a time to be focused and professional. But there's also a time to be silly and immature -- yes, even when you have an impressive 10-word title that no one but you understands. (Sorry, Senior Supervisor of Quality Control and Other Specific Duties. I'm sure your job is very important.)

So that's where these geek-friendly pranks come in. With this list, you'll have more than enough tricks to balance out the treats floating around your office this Halloween. Every workplace needs its resident prankster, and this is your chance to step into those shoes with style.

A few words of warning: Some of these pranks will require you to edit advanced settings within your operating system's configuration. If you aren't familiar with those settings and make a mistake, you could really screw stuff up. And, equally important, if you cross the line between good clean fun and mean-spirited antics, you could really make someone mad.

To sum up: Proceed at your own risk and only if you feel fully comfortable with the steps involved. Prank often, but prank wisely. And, for the love of God, don't tell anyone I'm the jerk who put you up to all of this.

Capisce?

1. The Sound of Amusement

The Prank:

Let's start things off with a bang -- or, to be more accurate, a baa. For our first prank, you'll catch your cubicle neighbor off-guard by toying with his system sound files. Changing the sounds altogether is too obvious; instead, edit the existing sound files to add unexpected noises at the end.

The Process:

Using a simple WAV editor like Audacity, open a commonly used system sound file such as the e-mail notification alert (typically found in the Media folder within the Windows directory). First, add 15 to 30 seconds of silence to the end of the file. Then, after the silence, tack on the sound of a sheep baaing, a fly buzzing, or whatever else tickles your funny bone. (You can find plenty of free sound effects on sites such as WavSource.com and SoundAmerica.com.)

Drop the finished file into your co-worker's Media folder, using the same filename as the original. Make sure to back up the old file first so you can restore it later.

The Final Product:

The next time your co-worker gets an incoming e-mail, your strange sound will follow -- and, thanks to the built-in silence, it'll be distanced enough from the normal sound that he won't know what hit him. How baaaad is that?

    A very easy prank is to reverse the left and right mouse buttons. You can do it in the Mouse Properties screen. Most people do not know that this can be done and it is very easy to remove your prank.When I am shopping for a new computer, I do this before I ask a salesperson about the computer. You can tell if they know their product and it is also hilarious to watch them reboot the computer, try another mouse, etc.

    Several of these pranks will get you fired in most corporate environments. And none of them are funny enough to take that risk.

    1) for the less intrusive prank: send a co-worker a message using the net /send command (in command prompt) saying "You're PC is infected" or whatever. If configured correctly, it will display a popup on your co-worker's monitor. 2) "borrow" your co-worker's cell phone (without them knowing) and toss it into the drop ceiling that is directly above them. then throughout the day, call it. they wont be able to find it and will think you're crazy when you suggest that maybe its in the ceiling.

    how about using ssh or some kind of remote access to run festival or some command line driven text to speech program and make the computer talk.

    My small company would never tolerate any of these pranks, I need something less destructive/disruptive. Plus, we all have password-protected systems... bypassing that alone would be grounds for dismissal.
