Everytime this shows up I wonder if this is really a male nipple or if the creator used a female one just for extra laughs. If it was a serious thing that people actually did it would be hilarious if they were replacing one female nipple for another.

Somehow also reminds me of a story about a singer's album cover released during the latest military dictatorship in Brazil (it was a heavily censored period). Folks went out of their way photographing a woman's asshole with a marble ball on it until they managed to get one that looked like an eye - then used that picture as the album cover.
