Prank - Play a video at startup

This one is pretty annoying. Even though it won't take much time for the victim to figure out what the hell is wrong but he won't be able to fix it easily. All you have to do is add a simple command to play a media file (a f**ing boring/annoying video) in his start up applications.

So, when he logs in before he gets to the desktop the video will start playing and because of the other loading application it will take him quite some time to get rid of it. You can use the following command with VLC.

[shredder12]$ vlc - -fullscreen - -volume 1024 <video_file>
