Clichéed sayings

A category for articles whose titles consist of any oft-repeated saying, statement, claim, proverb, piece of advice, question etc., whether eminently sensible or batshit silly. This category should not include articles about eponymous books, films, articles, websites etc., and should generally only include titles that can stand alone as complete sentences (with the exception of snowclones such as "I'm not prejudiced, but...") Some of these may function as thought-terminating clichés.
