The big question on Lost (well, one of them, anyway) is: What is in the coffin?
I think there is another coffin in the coffin, and then another coffin inside of that, and so on, and so on, until you get a really teeny tiny coffin. A really cute one. It's kindof like those famous russian dolls. And inside of that one is a quarter.
Okay, sure. Why not? It makes as much sense as any of the other "in the coffin" theories. And the Beatles' russian dolls picture is just too cool, don't you think?
