If you were to survey the average person I'm quite sure that he or she would know the most basic and rudimentary "facts" about Jesus Christ.
You'd be surprised...especially with your first fact of him being Jewish.
Also...reminding people that if Jesus was to return (if all that is true) he wouldn't be white (instead would look like the American's stereotypical idea of a "terrorist" - middle east garb, turban, very tan skin, long beard, etc) is a fun thing to do
