‘Get Your Arab On’, a festival tonight in New York features Arab-American comedians chipping away at ethnic fears. These Americans, many raised Christian, but now profiled as in airports, are using humor to show the futility of vilifying others because of their culture, creed, or color. The fourth annual Arab-American Comedy Festival is featured today in Christian Science Monitor. (photo) Festival Co-founder, Maysoon Zayid, performing, by Johnny Farraj
