Jeopardy does not reuse Final Jeopardy clues. However, due to the category and wording of a Final Jeopardy clue, it is possible to have duplicated Final Jeopardy questions. An example of this would be the episodes of March 18, 2008 and September 23, 2009. Though very different clues, the response to each is 'Who is Guy Fawkes?' There have been instances where answers/questions have been reused in the regular rounds of Jeopardy. Also, the writers have been known to take answers that remained unopened at the end of a round and turned those answers into a hodgepodge category in single or double jeopardy in a later episode.
