These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Harsher in Hindsight: The episode "I'm Here to Kill a King", which deals with a political assassin, was originally scheduled to air on the night of November 29, 1963. After the real-life assassination of President John F. Kennedy exactly one week earlier, CBS pulled the episode from its schedule, and it was not seen until the show went into syndication.
