ask a silly/stupid question (and you'll get a silly/stupid answer)

ask a silly/stupid question (and you'll get a silly/stupid answer)

A response to an unsatisfying answer or to one that is a put-down. Eric Partridge believed this nineteenth-century retort evolved from the proverb ask me no questions, I’ll tell you no lies, but the two clichés are not identical.
