Hatred is the subject of this feisty sketch show, Triplette’s fourth. Roommates offstage, the three women turn head games into heady humor by exploiting the power dynamics of everyday and only-on-stage situations: a hungry grocery shopper clashes with a free-sample attendant, a woman grows jealous of her shadowy “understudy for life.” In one sequence they play a scene of shopping for lingerie three times: at first their casual banter is polite, then it’s slightly acidic, and finally they vociferously voice the vituperative unsaid. All these quirky performers are talented and move at a “catch us if you can” pace–there are even gags during blackouts. But vibrantly funny Laura Grey (who resembles a young Chrissie Hynde) could command her own spotlight on any stage. Through 4/8: Fri-Sat 10:30 PM, Apollo Theater studio, 2540 N. Lincoln, 773-935-6100, $7-$10.
