A Kiwi and an Aussie were sitting around talking one afternoon
over a cold beer.
After a while the Aussie says to the Kiwi, "If I was to sneak
over to your house and shag your wife while you were off fishing,
and she got pregnant and had a baby, would that make us
related?"
"The Kiwi crooked his head sideways for a minute, scratched his
head, and squinted his eyes thinking real hard about the question.
Finally, he says, "Well, I don't know about being related, but it
would make us even."
