Sometimes saying nothing is scarier. There is not much that would be creepier than hearing a deep husky breathing on the phone. Not to mention, you don’t want to risk your girl recognizing your voice. You can easily block your phone number when you call her so the caller id will just read unknown or restricted. For all of those people without extra money to spend on a prank, this is the one for you. It won’t cost you a dime and the memory of her calling you up scared out of her wits will be yours forever.
