Everybody, Somebody, Anybody, and Nobody!

Once upon a time, there were four people. They were named Everybody, Somebody, Anybody, and Nobody. An important job had to be done. Everybody was sure that 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 and that Somebody would do it. It ended up, however, that Everybody blamed Somebody when Nobody did what Anybody could have done!
