I wrote one, although I admit it's not that good. Here's mine...''Knock Knock..who's there..Half two... hafff to..who? ..have to go back to the island, Kate @ #Lostjokes''.....all in good fun. My "Lost" experience has been incredible and thanks for not totally ridiculing my often silly theory posts. I truly take the show seriously, but try to lighten up between these intense episodes of late. Only 5:45 until episode #616. Unbelievable, of course, I do still believe, to quote the band Chicago..."It's only the beginning..."
