In this one-woman show, writer-performer Kara Buller creates a handful of eccentric characters who reveal their true selves inadvertently. A desperate 1950s housewife uses chirpy party tips to cloak her viciousness, a mullet-wearing lesbian camouflages her rage with a stand-up routine, and a seemingly gentle New Ager can't let any of her grievances go. Though none of these characters is new, Buller makes each one real--and really funny. But glacially paced blackouts slow the show, and you have to sit through Tony Sam's long, torturous warm-up act, a work in progress called Have You Seen My Marbles? that fails to make the character of a bumbling scientist funny. Through 8/25: Fri 8 PM, Cornservatory, 4210 N. Lincoln, 773-343-9613, $5-$10.
