Has anybody noticed...?

It is 1 day from April Fool's Day. A prankster's dream.

Some pranks:
Hurry Up
Change the cursor on the victim’s computer. Go to Start->Settings->Control Panel->Mouse, and select the “Pointers” tab. Then change the cursor to the hourglass image. Now the victim will think their computer is stuck on a task endlessly.

Disappearing Desktop
First, take a screen shot of the victim’s desktop (press the “Print Screen” button). Then open up a Paint program and press “Paste.” Save the image in bitmap format and quit Paint. Set this image to be the Desktop background image (right-click on the desktop, choose Properties, click the “Display” tab, press the “Browse” button, find your image, hit “Open,” then “OK”). Finally, hide all the desktop icons (right-click on the desktop, choose “Arrange Icons By,” then unclick “Show Desktop Items.” Now their desktop will look normal, but when they try to click on the icons nothing will happen!

Let Me Out
This trick works best on the bathroom door, but can be done on other rooms as well. Remove the doorknobs and turn them around so the lock is on the outside. Then push the button or turn the lock so it will lock automatically when the door is shut. The victim probably won’t notice the switcheroo and will lock themselves in.
