I grabbed this from here.
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.
