On May 18, 1889, a boy was born to farmers Natalae and Giovanna Falco that the world was not prepared for. Frank Lentini was the fifth of a family of twelve children. Frank was born with a parasitic twin, which was attached to his body at the base of his spine and consisted of a pelvic bone, a set of male genitalia, and a gull-sized leg extending from the right side of his hip, with a small foot protruding from its knee.
