There are 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 realised that Everybody wouldn’t do it.

Everybody blamed Somebody 

    When Nobody did what Anybody could have done.
