leprasmurf asks: "Here I sit with Administrative rights to a public computer at work, and I'm trying to think of how I can have fun with my co-worker's profiles. I'm running low on ideas. I've done the 'copy 50 million folder shortcuts to their desktop' one and if he forgets to lock his terminal one of these times I'm going to do the print screen and hide all his icons one, but what else is there? Surely there are some harmless pranks an administrator can do without resorting to downloading programs for assistance. Any suggestions?"
