A census taker in a rural area went up to a farmhouse and knocked.

When a woman came to the door, he asked her how many children she had and their ages.

She said, "Les' see now, there's the twins, Sally and Billy, they're thirty-two. And the twins, Seth & Beth, they're twenty-six. And the twins, Penny and Jenny, they're twenty-four . "
 

"Hold on!" said the census taker, "Did you get twins EVERY time?"

The woman answered, " Heck no, there were hundreds of times we didn't get nothin."
