A teacher in a rather backward rural area, attempted to broaden the outlook of her class.  She asked the students to write an essay on their views of foreigners...

All the children turned in more or less acceptable pieces except for little Billy, whose essay, in full, read: "All foreigners are bastards."

The shocked teacher made no direct comment but devoted her next lecture to a description of Greek architecture, Roman law, English drama, German music, Italian poetry, Russian novels, Chinese philosophy and African sculpture.  She then asked the class to write another essay on foreigners.

When she finally got little Billy's paper it read, in full:

"All foreigners are bastards.  Some are clever bastards."
