Frozen desktop
Temporarily ‘freeze’ your friend’s desktop by doing a ‘Print Screen’ of their work area and saving it as their wallpaper. The next step is to minimize the taskbar and hide their desktop icons. They’ll never know what hit them as they try desperately to click on the ‘frozen’ icons.
Play switch!
If you’re in an office with computers really close to each other, you are in luck. Pick a person whose computer is next to yours or back to back. Make sure they have really long cables. Before the person who works across from you gets to his station, unplug his keyboard, plug yours into his computer and open a word processor on his terminal. When the person gets back to work on his PC, start typing and be prepared to double in laughter. You can also do this with mice and monitors.
A mousy trip
Tape the trackball to the insides of the mouse and watch with a straight face as your friend tries to hunt the mouse.
Smooth operator
From the Control Panel, change the doubleclicking speed of the mouse to the fastest it can be. To add to this, switch the settings for the mouse buttons from right-handed user to lefthanded user or the other way around
Sound start
Record your friend saying something stupid with a whole lot of sound effects. Then sneak up to their computer and pop it in as their Windows startup. Warning: your friend will probably have a lot to say to you afterwards ‘offline’.
Keyboard capers
Pick one key that is used most often, for example ‘E’ or ‘I’, take the spring out from under that key. Or how about witching the ‘M’ and ‘N’ keys? You can get away with this unnoticed for sometime. Works best when the person has a password containing the letters ‘M’ or ‘N’. If that doesn’t sound daring enough, how about changing your victim’s keyboard setting to a different layout. (Mind you, keep your windows install disks handy in case anything goes wrong.)
Where have all the icons gone?
Try to take control of a computer, go to Control panel > Display and change everything to black. Have fun watching the PC user trying to find all those icons.
Virus alert!
E-mail someone you know every hour, on the hour, sending them a warning about the deadly virus that’s hit town.
