Prank - Xkill

Go to Applications-> Preferences -> startup applications and add xkill to start at the time of login.

If you are not aware what xkill does, then open a terminal and enter xkill. This will turn your regular mouse pointer to a cross(x) symbol and if you click on window the process associated with it will be killed. Try clicking on the terminal where you typed xkill, this will end the terminal and all the processes associated with it (even xkill will get killed).

So, I guess now you can understand how this command can cause disaster sometimes. So, be careful while using it. And remember that we linuxers are here to help others ( and have fun sometimes  ) but definitely not to cause harm ( sounds like a "superhero" quote ).
