" The 1940s was the heyday of pledges and oaths.* In Boy Scout halls, homerooms, and Elks lodges, people were accustomed to signing on the dotted line or standing and reciting, one hand raised. Even the Clean Plate Club—dreamed up by a navy commander in 1942—had an oath: “I, ____, being a member in good standing . . . , hereby agree that I will finish all the food on my plate . . . and continue to do so until Uncle Sam has licked the Japs and Hitler”—like, presumably, a plate.
