From Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb
[Strangelove's plan for post-nuclear war survival involves living underground with a 10:1 female-to-male ratio
General "Buck" Turgidson
Doctor, you mentioned the ratio of ten women to each man. Now, wouldn't that necessitate the abandonment of the so-called monogamous sexual relationship, I mean, as far as men were concerned?
Regrettably, yes. But it is, you know, a sacrifice required for the future of the human race. I hasten to add that since each man will be required to do prodigious... service along these lines, the women will have to be selected for their sexual characteristics which will have to be of a highly stimulating nature.
