There is enough variety in there, to scare the pigeons out of your unsuspecting friends & family.
Set up Creepy Tunes with either the short or long delay, depending on when you want the tune to go off.
Oh yes, and one last thing - make sure to make a video of your prank targets wetting their pants!
