That made me think of this dialogue in the movie "Moonstruck":
Rose: Why do men chase women?
Johnny: Well, there's a Bible story... God... God took a rib from Adam and made Eve. Now maybe men chase women to get the rib back. When God took the rib, he left a big hole there, where there used to be something. And the women have that. Now maybe, just maybe, a man isn't complete as a man without a woman.
Rose: [frustrated] But why would a man need more than one woman?
Johnny: I don't know. Maybe because he fears death.
[Rose looks up, eyes wide, suspicions confirmed]
Rose: That's it! That's the reason!
Johnny: I don't know...
Rose: No! That's it! Thank you! Thank you for answering my question!
