Mysterious Island of Beautiful Women1979

Gordon Duvall:
I figure those girls for 26... 27. And Lizabeth for 32, and her sister's probably the same age.

Mike Stapleton:
Why do you say that?

Gordon Duvall:
Well, no adult ever taught those girls to count. There's no seven or nine in their language. I don't think they've ever been around any adults, unless it was someone whose mind was arrested when they were five or six.

Mike Stapleton:
That explains their innocent qualities.

Gordon Duvall:
Innocent as black widow spiders, my friend. There are no men on this island, and never will be. Oh, some natives come here once in a while for a manhood ritual. The child was a result of rape. And the girl Jo Jo, she had a baby. A boy... and they killed it.
