When Harry Met Sally... Crystal remembers saying, "'We need something for Sally to talk about,' and Nora said, 'Well, faking orgasm is a great one,' and right away we said, 'Well, the subject is good,' and then Meg came on board and we talked with her about the nature of the idea and she said, 'Well, why don't I just fake one, just do one?'" Ryan suggested that the scene take place in a restaurant, and it was Crystal who came up with the scene's classic punchline – "I'll have what she's having." In 2005, the quote was listed 33rd on the AFI's 100
Orgasm biologists, and there is increasing scientific awareness of the female proceptive phase. Though Dixson classifies humans as mildly polygynous in his survey of primate sexuality, he appears to have doubts, when he writes, "One might argue that ... the female's orgasm is rewarding, increases her willingness to copulate with a variety of males rather than one partner, and thus promotes sperm competition." Ryan and Jethá use this as evidence for their theory that partible paternity and promiscuity were common for early modern humans. The clitoris is homologous to the penis; that is, they both develop from the same embryonic structure.
