"Keep 'em [Blank]" was the format for a number of slogans surrounding the US armed forces fighting in World War II. In particular, "Keep 'em Flying" was both a motto in support of the Air Force and later the title of a 1941 film in which two circus performers join Army flight school. Other slogans included, "Keep 'em Sailing", "Keep 'em Rolling", "Keep 'em Smiling" (a letter writing campaign), and, of course, "Keep 'em Fed", which encouraged citizens to ration food in support of the war effort and was frequently used by trade companies to advertise their donations to the troops.
