"Humans are the only animals that have children on purpose with the exception of guppies, who like to eat theirs"
About this Quote
The specific intent is to needle middle-class pieties about family. Having kids "on purpose" sounds like enlightened planning, but it also sounds faintly clinical, like ordering a lifestyle upgrade. O'Rourke's subtext: modern humans don't just reproduce; they schedule, justify, and narrate reproduction until it looks like a virtue badge. By contrasting us with animals that breed without self-congratulation, he implies our real specialty isn't parenting - it's rationalization.
Context matters: O'Rourke's libertarian-leaning, anti-sentimental humor often treats earnest social scripts as targets. This line lands in an era when contraception made "on purpose" newly literal, and when cultural wars over family values turned childbearing into ideology. The guppies are his escape hatch from sanctimony. If we're going to moralize biology, he reminds us, biology is fully capable of moralizing back - with teeth.
