Tricks to annoy friends who are using your system

There are instances where your friends or enemies come to your place and use your system without your permission. Or It might be the case where there is no other option left for you than to give it. So, If by tricks you what simple ways to annoy people, then I can suggest a few :

Tricks to annoy friends who are using your system:

Trick 1 : Hide your icons - First take a screenshot of the desktop. Then delete all the shortcuts, or cut/paste them in a separate folder. Now make the screenshot your wallpaper. It would show the old icons, and
anybody who tries to click on them would be left scratching his/her pretty head.

Trick 2 : Loopy Shortcut - create a folder (anywhere, but i generally do it on the desktop). Give it an interesting name like "personal photos" or "dont open". Then create a shortcut inside that folder, and link it to that folder's address. Then rename that shortcut with some other interesting name. Thus anybody who clicks on that shortcut would be rerouted to the same window, which basically, is doing nothing. This annoys people to no end (similar to the above 'clicking icon problem').



Did you expect many?? i think these are sufficient enough to make them irritated :P
