ask a stupid question and you'll get a stupid answer

ask a stupid question and you'll get a stupid answer

Also, ask a silly question. Your query doesn't deserve a proper answer, as in Am I hungry? ask a stupid question! One authority believes this idiom is a variant of ask me no questions and I'll tell you no fibs, which appeared in Oliver Goldsmith's play She Stoops to Conquer (1773) and was frequently repeated thereafter. [Early 1800s]
