I have to wonder how many stories with tragic endings contain that phrase.
This also gets into the area of what constitutes a tragedy. For example, if you tell your wife, "Honey, on the advice of Paris Hilton, I'm breaking out the camcorder tonight to spice up our zesty session," that could lead to tragedy. However, if your wife says, "Honey, I've been thinking about those stories about Paris Hilton's videotapes and I'd like to try that..." then that most likely doesn't turn into tragedy (unless the tapes get mixed up at your next family get-together or church function).
