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, Margie & Mikey, they're eighteen. And the twins, Pam & Sam, they're sixteen. And the twins, Sissy & Missy, they're fourteen."

"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'!"
