You are trapped on a desert island, with no hope of rescue. The island is so small that exploring it will only engage your interest for a week or two, tops. There is no companionship, nobody to talk to, not even so much as a volleyball to stuff with hair and imbue with a personality. (On the other side of things, you are a pretty serviceable fisherman, so food is not a serious concern.)
What you DO have, is a TV and DVD player, hooked to an otherworldly, eternal power source. And a plane is coming, with a cargo full of DVDs that it just might drop onto your tiny island. You have just enough rocks at your disposal to write the names of three actors or actresses that the plane might see.
