Congenital

Frank Lentini, of Sicily, was born with a strange condition. He has a parasitic twin attached to his body, giving him three legs, four feet, and two sets of genitalia. The partially formed twin was fused to Lentini’s body at the pelvic bone. Lentini came to the United States when he was only 8 years old and landed the only job available to him…a side-show attraction in a circus. He joined the Ringling Brothers Circus first, but eventually worked for every large circus in the United States.
