( hahaha – next time ask him if he is a Mountain Jew??)
Wikipedia:
Today, Jews in Azerbaijan mainly consist of three distinct groups: Mountain Jews, the most sizable and most ancient group; Ashkenazi Jews, who settled in the area during the late 19th-early 20th centuries, and during World War II; and Georgian Jews who settled mainly in Baku during the early part of the 20th century.
Mountain Jews or Caucasus Jews, also known as Juhuro, Juvuro, Juhuri, Juwuri, Juhurim, Kavkazi Jews or Gorsky Jews, are Jews of the eastern and northern Caucasus, mainly Azerbaijan, and various republics in the Russian Federation
