Once upon a time, there were four people;
Their names were Everybody, Somebody, Nobody and Anybody. Whenever there
was an important job to be done, Everybody was sure that Somebody would do it.
Anybody could have done it, but Nobody did it. When Nobody did it, Everybody
got angry because it was Everybody's job.
Everybody thought that Somebody would do it, but Nobody realized that Nobody
would do it. So consequently Everybody blamed Somebody when Nobody did what Anybody
could have done in the first place.
