i know a good one change they keyboard to dvorak or organize a persons keys in abc order heheh

I have one. Like vielle said, change the keys on it where letters are numbers and numbers are symbols and those are letters, then mix them all up randomly (but still in teh same categories) then set it where any key pressed initiates shutdown in 30 sec. ;)

switch all the icon names and pictures in the desktop

either A)slide show their background and add a scary picture in it or B) find one of those "scary maze" banshees and set it as their screen saver.

I got one. Change thier screensaver and their background to random pics of goats... also thier internet browser theme to either goats or my little ponies. I had this done to me once and it was not fun.
