A blonde was sitting on her porch when a young man walked up with a pad and pencil in his hand.
"Okay, what are you selling?" asked the blonde.
"I'm not selling anything, ma'am," the young man replied. "I'm a Census Taker."
"A what?" the blonde asked.
"A Census Taker," replied the young man, "We are trying to find out how many people are in the United States."
"Well," the blonde answered, "you're wasting your time with me, I have no idea."
