Plot
It's in-law vs. in-law when the Olesons meet the parents of their son-in-law, Percival (Steve Tracy), for the first time. Inevitably, the hidebound Harriet Oleson (Katherine MacGregor) clashes with Percival's Jewish father, Benjamin (E.M. Margolese), over whether or not Nellie (Alison Arngrim) should raise her unborn child as a Jew or a Gentile. As it turns out, Nellie takes a hand in solving the matter -- by giving birth to twins! ~ Hal Erickson, All Movie Guide
