Adanor, you are of course correct and the show Red Dwarf is a comedy science fiction show which has achieved a cult status. For the record the show was not making fun at the death of Kennedy but at the conspiracy theorists.
It was only 1 particular episode from a whole series of shows made over 20 odd years and actually dealt with Kennedy very sympathetically. It is a complicated, and when watched, hilarious (well us fans think so)! story.
This particular show while having the shooting of Kennedy as a major part of it was not in fact ABOUT it. At the risk of making things even more confusing the episode involved time travel, alternative universes and a quest by one of the main characters
(from the future) travelling back in time in a quest for a Curry when the space ship "Red Dwarf" runs out.
In so doing they accidently arrive in the Texas Book Depository and nudge Lee Harvey as he is about to shoot, causing him to miss. After more to-ing and fro-ing Kennedy ends up surviving the assassination attempt and history is changed as a result.
In the new reality Kennedy eventually ends up impeached and thrown in jail for his womanizing and other such misdemeanors he was famous for, resulting in him being remembered as a criminal and the whole future as we know it is changed for the worse...remember this is light comedy! so the whole thing is done "Tongue in cheek"
To make a long story short, to "fix" things the Kennedy from the "new" reality is told of the situation and agrees to brought back in time to the grassy knoll where he shoots HIMSELF in the car thereby resetting the timeline to normal.
There is a LOT more to the story but you really need to know all the backstories of the characters and their interactions to get the full impact.
Also remember this is a British show not American so the whole thing may appear somewhat skewed to our American fans. As stated before the humour in this episode is aimed at the conspiracy theorists and there is actually a line from the show which states "it will drive the conspiracy theorists mad"
At the end of the episode Lister (the character looking for a curry) is STILL looking!!
NOTE: apologies to RD fans, I know the above does not do the show justice and misses out a considerable amount but I needed to explain that the Kennedy assassination itself was not the focus for the humour.
OK back to normal transmission and stories about 3 blokes from Yorkshire!:laugh:
