If human beings don't keep exercising their lips, he thought, their mouths probably
seize up. After a few months' consideration and observation he abandonded this
    theory in favor of a new one. If they don't keep on exercising their lips, he thought,
       their brains start working.
          Douglas Adams

Douglas Adams
