Well I just had to go and watch the "National Treasure" movie and I got a few clues from that... i'll post them with a spoiler format.... (highlight to read)
(also apologizes to anyone using a text browser.... try skipping this next part without reading it to avoid spoiling the movie...)
-------------=============Spoiler Start==============---------------
In the new national treasure Nicholas Cage kidnaps (or PresiNaps) the US President because he wants to know if there is really a secret book containing all the secrets of the united states.
this book supposedly is passed down from president to president and only they know it's secret location.
also supposedly this book contains the answers to many conspiracy theories..
the "Truth" about area 51, the Kennedy assassination and much more....
the president reveals the location of the book, and tells Cage's charecter that they will find what they are looking for there.. and then he says: "oh and do me a favor and check out page 47" (or something like that)
Later in the movie the President asks Cage if he read page 47, and if he (cage)could help him (the president) with the matter, cage answers something along the lines of "yeah, I can.. it will alter the world".
I swear on the pasta monster that I was completly distracted from the movie... every time they said 47 I was like... "Chief Delphi!!!" 
and that last quote I was thinking "He's talking about FIRST!!" 
--------------------========= End Spoiler =======---------------
I didn't even watch the movie... I was just looking for clues that could help solve the FIRST hints...
lol....
