While you're thinking of survival, I'm betting they want to hear junk like "The Beatles Collection on CD". LOL

The sacred order of survival is shelter, water, fire, food and the items should probably reflect that. You could add first aid in there, and a rescue item seeing as how it's a desert island scenario.

However, since I can rarely manage to be too serious about much of anything, I'd make the first thing I'd take "Les Stroud" so he could keep me alive while I lounged on the beach taking advantage of the time to get away from the world. HAHA
