I would eat Dave, lots of meals there...then i could use his skin to build myself a holy tent
I would send JJ off swimming, knowing that he wouldn't get far with his mouth open and that his floating body would attract fish for my din-dins
I would keep Ben, buried up to his neck in the sand. He would make a good jukebox when kicked and also if any ships were sighted, setting fire to his perm would make an excellent beacon
