I also remember “13th Hour” on channel 2 at midnight on Fridays.
One Friday (pre 1958) “The Thing” movie was being shown and Ch.2 had a bit from that movie during a commercial break(?), the Thing was trying to get into the building and the TV engineers played a looped repeat of the Thing opening the door, the background music they played was “I hear you knocking, but you can’t come in..”.
As kids my brothers and neighbor Harry Weir all laughed our heads off..!!
They don’t make them like that anymore, indeed!
