A piano player found his instrument to be out of tune
and therefore called in the local tuner, Mr. Orlando
Oppornokity. Mr. O. accordingly was summoned, tinkered
with the keys, and departed. The piano player was not
satisfied with the job, however, and called Mr. O.
demanding that he return and do the job right. Not on
your life, Mr. O. replied, "Oppornokity tunes but
once."
