Last week's episode of LOST left me breathless and thinking in web lingo (WTF!?) But during the episode, there was a fake commercial for the Hanso Foundation that included a phone number: 1-877-hansorg (1-877-426-7674.)
If you're a total freak about the show, you should call the number, more than once, it's free, and the information you get changes a little with each call. It gives some real insight to some of the mysteries, and adds a few more.
Then go to the website and sign up for the newsletter. Seriously.
