Children in the dark make accidents, but accidents in the dark make children.

A darkly comic aphorism built on a reversal: at first it evokes the everyday idea that children, unable to see well, are prone to mishaps. The second clause flips “accidents” into a euphemism for unintended conception—“an accident in the dark” producing a child. The humor depends on ambiguity in the word “accident” and on the parallel structure that makes the twist feel inevitable. As a piece of anonymous folk wit, it functions as a cautionary joke about sexual responsibility and the consequences of carelessness, while also poking fun at how people rationalize unplanned parenthood as mere happenstance.
