Still anxious to serve his country in the military, Jethro heads to what he thinks is an Army-reserve recruiting office, and is immediately inducted into the ranks of the costumed movie extras appearing in a Civil War epic. The confusion is compounded when Granny, spotting the maneuvers of the "Union Army," is convinced that the War Between the States is starting all over again. William Mims appears as the tippling bit player cast as General Grant, while Lyle Talbot is seen as the film's military advisor, Colonel Blake. The first episode in a three-part story arc, "The Reserve Program" first aired on November 22, 1967. ~ Hal Erickson, All Movie Guide
