In Cândido Godói, Brazil, a town of about 80 households, has 44 sets of twins. National Geographic follows a man who postulates that this is a result of the continuation of a Nazi Germany twin experiment from escaped Joseph Mengele, World War II's most wanted war criminal.
Mengele, known as "The Angel of Death," worked very closely with Hitler during WWII doing experiments with twins in Germany to help build a master race. After the war, he escaped to South America. As a result, twins began popping up all over South America. Just wild.
