Misleading people and making them laugh both require frustrating their expectations, something writer-performers Patrick O'Brien and Peter Grosz have mastered in this clever sketch show directed by T.J. Jagodowski. Facts are misrepresented in posters and playbills, and audience members are misdirected in various ways each night; the show itself offers a puzzling array of in-the-dark characters in vignettes ranging from several seconds to several minutes. In the sharply executed opening sequence, a couple's vacuous relationship is dramatized not by over-the-top caricature but by crisp pantomime--the two are going through the motions. And in one of many reflexive moments, a disoriented street artist draws a disoriented street artist who's drawing him. From its swinging-60s music and fashion to its elaborate blocking and sophisticated verbal motifs, Misled explodes with style and wit. Through 3/10: Fri 10:30 PM, I.O., 3541 N. Clark, 773-880-0199, $14 (includes admission to Friday performances of Baby Wants Candy: The Rock Musical--see separate Comedy listing for I.O.).
