الموسم 4، الحلقة 1: Two guests linked by one hilarious impersonation trace their roots from 1940s Brooklyn back to Jewish communities in Europe. Larry David discovers his German heritage by way of ancestors who settled in Mobile, Alabama in the mid-19th century — including one who became a slaveholding Confederate; Bernie Sanders gains greater understanding of his father’s dangerous childhood in Austrian Galicia during World War I. Both guests discover what happened to the family members who were still in Europe during the Holocaust — Larry David’s grandfather lost nine siblings; Bernie Sanders’ uncle, a member of the Limanowa Judenrat, heroically went head to head with a Nazi officer. Through DNA testing, our guests learn that there is more to their uncanny likeness than they ever suspected.
