Whose Job Is It?

This is a story about four people named Everybody, Somebody, 

Anybody, and Nobody.  There was an important job to be done and 

Everybody was asked to do it.  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 

wouldn't do it.  It ended up that Everybody blamed Somebody when 

Nobody did what Anybody could have done.
