Below are a few suggestions for some computer practical jokes. If you have any suggestions, please post them in the comments:
Note: Perform these practical jokes at your own risk, I am not responsible for the results.
Keyboards and Mice:
- Remove the ball from the computer's mouse on the older mechanical mice. If its the newer optical mice, stick a small piece of tape over the optical sensor.
- Unplug the mouse and/or keyboard from the back of the computer. If its a wireless keyboard or mouse remove the batteries from the device.
- Almost every computer is a rat's nest of cables, removing the right cable (power, network, keyboard, etc.) can cause frustration for the computer user.
- Any good computer user will have a surge suppressor power strip where their computer is plugged into. Some of these power strip have a breaker, sometimes they manually allow you to blow the breaker. This will basically make the power strip a useless piece of junk until the breaker is reset.
- This trick will drive the end-user mad, they will try to click on the desktop and believe the computer is frozen when nothing works. I have seen people reboot their computer several times before they figured out what is wrong. Use with caution, save all the user's work before using this trick.
- Take a screen shot of the computer's desktop (press PrtSc screen button). You might want to try taking the screen shot with open application windows, it might add to the realism.
- Then open a graphics program like MS Paint (under Start menu | All Programs | Accessories) and Paste the image into the application. Save the file into the C:\WINDOWS\ directory as a bitmap file (.BMP) and set it as the desktop background. (Note: if you're using MS Paint there is a command under the File menu to do this.)
- Then remove the icons from the users desktop, put them in a folder under the user 's'My Document' folder. You can right-click an empty space on the user's desktop, and uncheck 'Arrange Icons By > Show Desktop Icons' (Note: you may have to cycle through [press Alt-Tab] an application that fills the screen to force the desktop to refresh it self)
- For extra realism, you can hide the taskbar at bottom of the screen. (Hover the mouse over the top edge of the bar until you see the up/down arrow, then click and drag the taskbar to the bottom of the screen)
- Turn the speaker volume up real loud on their computer and walk away.
- Try playing with the computer settings, such as the monitor, cursor, mouse and keyboard configuration in the Control Panels.
- Change the startup or other event sounds (such as changing the new mail sound, to something like the sound of someone passing gas [you know what I mean])
- Embed the following link into an email, and send it to your friends (http://img89.imageshack.us/img89/891/3dtetris8yi.swf). I promise they will hate you after you send it.
