When I was very young I was watching a "Friday the 13th" movie on tv with my Dad. (It is the series of movies with Jason, in case you don't know.) There was a scene with a little girl saying her prayers at her bed with Jason hiding underneath watching her. My Dad said to me "see, if you're good Jason doesn't kill you." Scared me for years. Thanks a lot Dad.
