Comedy is tragedy plus time, but the best material comes from picking at the wound before the scab forms. Which is certainly the case with Ivor Dembina, whose one-man show is called “This Is Not a Subject for Comedy”—an appropriate title, given that his topic is the Middle East. But the London-based Jewish comedian does not offer the usual paeans to Israel. “We Jews should give up the occupied territories,” he says. “But I think we should hang on to New York.” Ba-da-boom. Dembina also practices what he calls “SadoJudaism.” He “enjoys being beaten—but not in business.” Again, ba-da-boom, though this seems as much true confession as comedy. Complementing Dembina on the bill is Tissa Hami, a Muslim comedienne who performs in Islamic hijab. The Boston-based Hami says, “It was scary growing up Iranian in this country. But when other kids teased me, I threatened to take them hostage.” Hey, better the ba-da-boom than the bomb. Leave your preconceptions at the door at 7:30 p.m. at the Warehouse Theater, 1021 7th St. NW. $10 (proceeds benefit Comedy for Peace). (202) 783-3933. (Dave Nuttycombe)
