While hiking in the woods, Nate and Sam found this huge rock which had
an old iron lever attached to it. Etched into the rock was the following
inscription: "If this lever is pulled, the world will come to an end!"
        Nate wanted to pull the lever and see what would happen, but Sam, being
a paranoid pessimist, greatly feared this! He said to Nate that if he
tried to pull the lever, he'd shoot him!
        In a daring attempt, Nate lunged for the lever, and sure enough, Sam
shot him!
        What is the moral of this story? - Better Nate than lever!
