Hold the Laughter

S10 E5: Henry Louis Gates, Jr. uncovers the roots of comedians Bob Odenkirk and Iliza Shlesinger--two very funny people whose family trees brim with stories that are more drama than comedy. Moving from Napoleonic France to Nazi-occupied Poland to the castle of a European duke, Gates introduces them to relatives who took great risks and overcame enormous hardships for the sake of their families.
