On any February 29th (leap year), look at the photo of a missing person on a milk carton. The picture will be of an old man who looks like a murderer. Whatever you do, don't call the number on the carton on the same day you looked at the picture, or else a voice on the other end will tell you that you're going to die. The next February 29th of the next leap year, at the exact time of calling the number 4 years ago, you will die of a heart attack immediately. You will only be free when someone gains your invisibility and time comes for him to take your place. As the man on the milk carton.
