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."
