I Love Lucy: Drafted (1951)

Synopsis
A series of misunderstandings lead Lucy (Lucille Ball) and Ethel (Vivian Vance) to believe that their husbands have been drafted into the Army -- while Ricky (Desi Arnaz) and Fred (William Frawley) become convinced that their wives are pregnant. Things come to a head when the girls plan a going-away party on the same night that the boys stage a baby shower. When this episode originally aired on Christmas Eve of 1951, longtime comedy foil Vernon Dent made an appearance as Santa Claus in the closing scene; this sequence has since been cut from all syndication prints. ~ Hal Erickson, All Movie Guide
