I heard the strangest report on NPR about 'numbers stations' - shortwave radio stations where people just count numbers somewhat at random. It reminded me of the scene in Lost where the guys on the island hear the Frency lady reading over the radio on the island.
Even if you don't like Lost, listen to this, it's very freaky: linky
I wonder if this was an inspiration to the guys writing Lost. Even if not, it's a strange bit of serendipity.
