Twins!

But not in the cool sexy way. Not even in the intellectually aware but rarely realized "hey, I'm actually married to a twin" way. [They totally look different to me.]

But instead in the creepy, Nazi, Josef Mengele-South American-experimentation kind of way. In-sane-o.

Nazi angel of death Josef Mengele 'created twin town in Brazil' - Telegraph:

"...Mengele fled Europe for South America in the face of the Red Army advance in January 1945

The steely hearted "Angel of Death", whose mission was to create a master race fit for the Third Reich, was the resident medic at Auschwitz from May 1943 until his flight in the face of the Red Army advance in January 1945.

His task was to carry out experiments to discover by what method of genetic quirk twins were produced – and then to artificially increase the Aryan birthrate for his master, Adolf Hitler.

Now, a historian claims, Mengele's notorious experiments may have borne fruit.

For years scientists have failed to discover why as many as one in five pregnancies in a small Brazilian town have resulted in twins – most of them blond haired and blue eyed.

But residents of Candido Godoi now claim that Mengele made repeated visits there in the early 1960s, posing at first as a vet but then offering medical treatment to the women of the town.

..."There is testimony that he attended women, followed their pregnancies, treated them with new types of drugs and preparations, that he talked of artificial insemination in human beings, and that he continued working with animals, proclaiming that he was capable of getting cows to produce male twins..."
