A famous professor of great erudition was visiting a village one day. He sat in the local
coffeehouse where the village men gathered around his table to listen to him expound on one
subject after another.
Finally one of the villagers interrupted the professor with the following proposition.
“I’ll ask you a question, my dear professor. If you can’t answer it, you’ll pay me ten dollars.
Then you ask me a question, and if I can’t answer it, I’ll pay you two dollars. This is fair,
” continued the villager, “because you’re a man of great knowledge and education, while I’m
simply an ignorant peasant.”
The professor accepted the proposal, and the villager asked his question:
“What creature has one leg and four heads?”
After thinking for a long while, the professor admitted he didn’t know, so he
paid the villager ten dollars.
The professor then asked the villager to answer his own question. “Sorry, but
I don’t know either,” replied the villager as he paid the professor two dollars.
