It is true that armadillos have spread leprosy to humans in the United States (they are used as lab animals to study leprosy) but in order for a human to have sexual intercourse with an armadillo "his" penis would have to be the size of a cats penis or smaller. I am 100% sure the article is a fake.

From your link: "WNDR assumes however all responsibility for the satirical nature of its articles and for the fictional nature of their content. All characters appearing in the articles in this website – even those based on real people – are entirely fictional and any resemblance between them and any persons, living, dead, or undead is purely a miracle."
