When I was a young man in the mid eighties, my family and I had 1 cable channel, HBO. In the summer of around 1985 I watched the movie "Poltergeist" over and over for over a month. The scene where the young boy in the family is attacked by a stuffed clown doll and pulled under the bed scared me so much that to this day when I turn in for sleep at night I must check under the bed to ensure the clown is not waiting there to pull me under, and I'm 31 now.
