One of the most interesting things, from the point of view of someone with three nipples, is the claim that Brian Jones of The Rolling Stones had an extra nipple!
Kenneth Anger and the Stones members had met in London 1967. Author Tony Sanchez, one of the group's friends, describes that Rolling Stones' Mick Jagger and Keith Richards (who attended Polanski's and Tate's wedding in 1967), and their girlfriends Marianne Faithfull and Anita Pallenberg, "listened spellbound as Anger turned them on to Aleister Crowley's powers and ideas". Anger had wanted to cast for Lucifer Rising Mick Jagger as Lucifer and Keith Richards as Beelzebub, but the Stones weren't keen on the idea. Anger claims Jagger agreed at first, then changed his mind.
Anita Pallenberg had met the Rolling Stones in 1965. She immediately began sexual relations with three out of the five members of the group. Anger, commenting on Anita, said, "I believe that Anita is, for want of a better word, a witch.... The occult unit within the Stones was Keith and Anita.... and Brian Jones. You see, Brian was a witch too." Anger says Jones had a third nipple, on his inner thigh; the extra nipple traditionally considered a certain sign of being a witch.
Fact or fiction? Well, supernumerary nipples tend to appear along the milk lines starting at the underarm and running down toward the abdomen - not on the thigh. However, stranger things have happened.
