"Desperate times call for desperate measures" is an aphorism which here means "sometimes you need to change your facial expression in order to create a workable disguise." The quoting of an aphorism, such as "It takes a village to raise a child," "No news is good news," and "Love conquers all," rarely indicates that something helpful is about to happen, which is why we provide our volunteers with a disguise kit in addition to helpful phrases of advice."
