Good Theater presents the Portland premiere of Vanya and Sonia and Masha and Spike, the hit Broadway comedy (and cheeky Chekhov knock-off) about middle-aged siblings whose staid lives are uproariously upended by the arrival of their sister and her “boy toy,” Spike. It opened last month at St. Lawrence Arts (76 Congress St., Portland) and continues through Nov. 20; tonight at 7 p.m. Tix: $22. 885-5883. stlawrencearts.org.
