As you may know, Team Darlton and their writers are fond of naming the surprise/cliffhanger for every LOST season finale. They do this to help maintain the surprise. Season 1 was The Bagel; Season 2 was The Challah; and Season 3 was The Snake in the Mailbox. In their podcast dated March 19, they revealed Season 4's code name: The Frozen Donkey Wheel. I have no idea what that is supposed to mean. It could very well just be an inside joke amongst the writers, but I'd love to hear your theories.
