Question for Quote Investigator: There is a family of comical sayings which highlight the paradoxical intelligence of fools and idiots:
(1) Nothing is foolproof. Fools are entirely too ingenious.
(2) They’re not idiot-proof because idiots are so damned inventive.
English humorist Douglas Adams employed this quip, but I do not know whether he coined it. Would you please explore the history of this joke?
