interesting bit from lostpedia:
"The episode was first broadcast on April 1st, 2009 (i.e., March 32nd), and it shares the central theme of the story March Has 32 Days from Mystery Tales No. 40, the comic book that was one of Richard\'s items presented to John Locke as a test in "Cabin Fever". In the 1956 story, a time traveler tries to alter history when he relives a day in his own past after struggling with the question of whether it would be possible to do anything differently if he had the opportunity to go back in time, just as Hurley and Miles struggled over the question. In the Summer 2008 ARG, the Lost creators embedded the hidden comment "March Has 32 Days" as a clue in the ARG\'s first email."
