An old man was sitting on his verandah, when a young man walked up with a pad and pencil in his hand.
“What are you selling, young man?” he asked.
“I’m not selling anything, sir,” the young man replied. “I’m the census taker.”
“A what?” the man asked.
“A census taker. We are trying to find out how many people are in Australia.”
“Well,” the man answered, “you’re wasting your time with me; I have no idea.”
