Chain Letter.

The Messenger of Death has an interesting way of getting victims. His assistant, Miss Smith, would write a letter where recipients would be told to pass it along. The person that failed in doing so would meet misfortune (mostly death). The Messenger of Death and Miss Smith would watch the person that broke the chain on a television monitor. After the victim's demise, The Messenger of Death would go back to his desk, and say to his assistant, "Take a letter, Miss Smith".
