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 pessamist, 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!
