Seven strapping men in swashbuckler shirts improvise a two-act Shakespearean play based on a title suggested by the audience. At the show I saw, "The Taming of the Jew" inspired the Bard's usual themes (religion, family, betrayal) and plot devices (murders, disguises, fortunes gained/lost) as well as an uncomfortably funny circumcision. Director-performer Blaine Swen, a veteran of long-form Shakespearean improv who swears they don't conspire during the intermission, has assembled a vigorous ensemble of actors and proven improvisers. Their experience doing Shakespeare flowers in the language: they relish iambic dialogue, execute perfectly timed asides, occasionally utter rhyming couplets (some hilariously forced: "Let us be quick-sa, and get to the bar mitzvah!"), and drop parodic phrases ("scurvenous knave," "midfortnight report") and well-placed anachronisms (the bar mitzvah had a DJ). Even the ending echoed the real plays: story lines resolved tidily--and uproariously. Open run: Fri 8 PM, I.O., 3541 N. Clark, 773-880-0199, $14.
