A man entered a café and announced to anyone who would listen that he was the smartest man around.
He turned to a table where another man was sitting alone, drinking his coffee.
“Sir, to prove how smart I am, I’ll make you a deal. For every question I ask where you don’t know the answer, you have to give me $5. But if you ask me a question I don’t know the answer to, I will give you $5,000.”
The man pondered the proposition then said, “Okay.”
The first man said, “How many continents are there in the world?”
The second man sips his coffee, looks up at the first man and says, “I have no idea.” He hands over $5.
“Now it’s my turn,” the second man says. “What animal stands with two legs, but sleeps with three?”
The first man pauses. He thinks for a moment, then frowns. After some time, he quietly admits that he does not know the answer. “Here is your $5,000,” he says, and hands it to the second man.
“By the way,” says the first man. “What was the answer to your question?”
The second man hands him $5.
