A Tennessee couple Dave and Edwina Kosmitus, both Bona Fide rednecks, had nine children.
They went to see their Doctor to get Dave "Fixed".
The Doctor asked them why had the come to the conclusion that they didn't want any more children.
Dave said that they had read a recent article in the newspaper that one out of every ten babies being born in the USA was Mexican, so as neither of them could speak Spanish they decided not to have another baby, if they couldn't understand it..
