Hurley gets the numbers from a gentleman he knew in the insane assylum to play on the lotto right? Or, rather, Hurley remembered him repeating them all the time when he was in. So maybe, that guy was actually a survivor of the island, someone who had stayed for the 480 (Or however many days they take on shifts) and typed in that code every 108 minutes? Or maybe, he is a big player in the plot later, like he planted that for Hurley and we'll see him as a main scientist on the island. Who knows, I just wanted you all to think about it. I think at the least, the guy used to be stuck on the island and used to be one of the people who kept typing the numbers in, that's why he sits and repeats them all the time. I'd go insane if i sat there for that long and did that every 108 minutes.
