Author Alexandra Robbins returned to the show to further discuss her investigation of Yale's infamous secret society, Skull & Bones, which she chronicled in her book Secrets of the Tomb. The "Tomb," a crypt-like building on the Yale campus that is headquarters to the club, is filled with human and animal skulls and relics of death and war, as well containing an underground tunnel, she noted. Various rituals take place among its undergraduate members, Robbins detailed, including paying homage to the Goddess of Eloquence - Eulogia, as well as a sharing of their sexual histories in what is called "Connubial Bliss."
Skull and Bones which was started in 1832, has around 800 living members at any one time, and according to Robbins its main purpose is to get members into roles of power, who then often help other members attain important positions. Interestingly, she noted that the CIA has a number of members who were Bonesmen, and at various meetings with members they were said to casually share secretive documents. Working for the CIA has been known to undergraduate members as an "employer of last resort," she added.
After a number of attempts, women were finally allowed as members of Skull and Bones in the 1990's, said Robbins, who also touched on her undercover investigation into sororities. While containing some secretive elements and initiations, she said she found that there were a lot of positive elements to sororities.
