Everybody--somebody--nobody

There was an important job to
be done and Everybody was sure
Somebody would do it. Anybody
could have done it, but Nobody
did it. Somebody got angry about
that because it was Everybody's
job. Everybody thought Anybody
could do it, but Nobody realized
that Everybody would not do it. It
ended up that Everybody blamed
Somebody when Nobody did
what Anybody could have done.
