My friend Dan Fienberg was inspired by the "Lost" finale to do the inevitable "Lost"/"Gilligan's Island" mash-up, which he calls "Uncharted," but which I would have called "Gilligan's Craphole Island." It's a very funny, more than a little post-modern take on the Oceanic Six, and what was really going on with the crew and passengers of the S.S. Minnow. You can read it here.
Reading it, meanwhile, reminded me of a "Gilligan"-themed spoof story that Matt Seitz and I wrote back in 2000, in which we tried to imagine (ignoring the reunion movies) how the castaways might have responded to being rescued. Hint: litigation is involved. You can read that one over at the NJ.com blog.
