Not only is it a bad idea, it is not a new one. I remember someone's funny computer column from one of the PC magazines at least ten years ago with a little batch file you could stick in someone's autoexec file. In those days the airport security types would make you turn on your computer and would watch it till you got the boot screen. This thing would put a 9... 8... 7... etc. countdown on the screen. I never heard if anyone got arrested for that stunt. Really, if you want to play pranks on people, do it to people who don't have guns.
