A man in jail does carpentry

      Several years ago, Andy was sentenced to prison.
      During his stay, he got along well with the guards
      and all his fellow inmates. The warden saw that
      deep down, Andy was a good person and made arrangements
      for Andy to learn a trade while doing his time. After
      3 years, Andy was recognized as one of the best
      carpenters in the local area. Often he would be given
      a weekend pass to do odd jobs for the citizens of the
      community.... and he always reported back to prison
      before Sunday night was over.

      The warden was thinking of remodeling his kitchen and
      in fact had done much of the work himself. But he lacked
      the skills to build a set of kitchen cupboards and a
      large counter top which he had promised his wife. So
      he called Andy into his office and asked him to complete
      the job for him.

      But, alas, Andy refused. He told the warden, "Gosh, I'd
      really like to help you but counter fitting is what got
      me into prison in the first place".
