A visitor to a goat show in Brazil did not hesitate to buy a hermaphrodite goat - a male goat that can be milked - when he first came across it. The goat is a clearly a Billy goat. And, translating the colloquial phrase "pai de chiqueiro", implies that it can be mated with a female goat. But, as seen in the video, the scrotum region apparently serves a dual purpose of being a set of udders that can be squeezed to get milk.
The interview is in Portuguese, but is subtitled for the non-Brazilian. Click through for more information than you'll ever need.
