Prank - Change the Launcher's settings

Many times people add application launchers on Desktop or on panel for quick access. And we can have a lot of fun with after changing the properties of such launchers. Jst try this:

Go to Accessories->Internet->firefox right click on the firefox option and you will see the options to add its launcher on Desktop or panel. Select any one of them. Lets say you selected the Desktop launcher. Now, right click on the launcher and select properties. In the properties window you will see options like : type, name, command, comment.

Now, the fun starts when we change the command from “firefox %u” to something like

xmessage “click ok if u r a jerk :P”

he will never be able to open firefox by clicking that icon ( ofcourse until he figures out the prank). You can even try runnng some script in place of the firefox command .
