When Lucy opens a telegram addressed to Ricky ordering him to appear at the Army's Fort Dix, she assumes that he has been drafted. Ethel suspects that Fred has been drafted as well. Their suspicions are confirmed when they see them drilling in the living room with brooms. They don't know, however, that Ricky and Fred are practicing a dance routine for a servicemen's show. To get their men "ready for the army," Lucy and Ethel take to knitting blankets and other things for them. They also plan a going away party for them on Sunday night. Ricky and Fred, meanwhile, think that the girls are pregnant. Chaos ensues when they plan a similar party (a baby shower) for that same night. (thetvdb.com)
