Everybody, Somebody, Anybody, and Nobody:
My Version

Let me tell you a story about four people; Everybody, Somebody, Anybody, and Nobody.

There was a job to do and Everybody thought that Somebody would do it.
Anybody could have done it, but Nobody did it.

Everybody knew that Anybody could have done it,
and Nobody realized that Somebody wouldn't have done it.

In the end, Everybody got mad because Nobody did, what Somebody should have done, and Anybody could have done.
