I can think of two good ways right off the bat,    1. drop a quarter or a dollar bill on the floor, the first one to have their eyes light up and go scrambling madly for it is probably a tribesman.    2. throw up the Aryan salute aka Nazi salute aka Roman salute and the first person who yells omg! nazi nazi nazi!! holocaust holocaust holocaust!' and calls the police and media on you is probably a Jew.    Other than that...anyone with a surname that has to do with precious metals and gemstones. Often times people with Berg or Stein in their name, but you can't always tell just by that because they could just as easily be ethnic Germans, Dutch or Swedes. If they have a Berg or Stein name and a face like a rat to go along with it and an extremely annoying voice then they are almost certainly a member of the Synagogue Syndicate. Anyone named Levin or Cohen, or something that sounds similar, except for Cohan with an 'A' because that's actually an Irish name. Anyone with White skin who's never done an honest day's work in their life but still has alot of money anyhow is most likely a Jew too. Those are just some of the ways that I can think of right of hand! :)
