A man named Martin was sitting on his porch, when this fella walked up with a pad and pencil in his hand.

"What can I do for you?" Martin politely asked. "You selling something?"

"No, sir, I'm not. I'm a Census Taker."

"A what?"

"A Census Taker. We're trying to find out how many people are in the United Kingdom."

"You're wasting your time here." Martin replied "I have no idea."
