  The Triple Nipple Club is a documentary shown on Channel 4 which explored the biological mystery of the supernumerary nipple. First broadcast on 2 January 2008, it was directed and produced by Dan Louw and commissioned as part of Channel 4's First Cut series. The film focuses on Louw's attempts to understand why he was born with extra nipples, a condition he shares with the likes of Mark Wahlberg, Lily Allen, and Tilda Swinton, as well as TV and film characters such as the James Bond villain Francisco Scaramanga and Chandler Bing from Friends. Fascinated and confused by this seemingly pointless mutation, Louw sets off on a personal journey of discovery to try and unwrap "the riddle of the triple nipple". He starts out by consulting the man in the street and a renowned teratologist, an expert in physical mutations. After testing the notion that extra nipples could be a sign of fertility, he discovers that they are actually an atavism, or evolutionary 'holdover'—a sign of how humans evolved.
  English pop-star Harry Styles confirmed in 2017 that he has four nipples as a result of the condition.
