Triple Nipple

"Bond: Anything distinctive about him?

Andrea: Yes, but how can I tell you? He's not like other men. [motions toward her chest] He has three...

Bond: Fascinating anatomical tidbit. But probably the most useless piece of information I've ever heard."

- The Man With the Golden Gun

Technically known as a supernumerary nipple or polythelia, a character with a triple nipple has just that: three nipples as opposed to the customary two.

Though it's used to mark a character as weird or unusual (and indeed, in folklore, an extra nipple is thought to be a teat that the devil sucks on), it's not particularly rare in real life. About one out of 18 people has one, though most of them only reach the stage of development where they just look like moles.
