The cheap, deceptive Howard is so jealous he plants a bug in his girlfriend’s apartment, and the girlfriend, Amy, feels incomplete because she’s still single and pretends to be pregnant so Howard will marry her. The ensuing high jinks in Norman Krasna’s tired 1967 script are completely unbelievable, relying on the worst stereotypes of male-female relationships, and neither Tony Fiorentino as Howard nor Jessica Granger as Amy is very likable. Yet this production manages to be somewhat charming under Donna Lubow’s brisk direction. The highlight is Marvin Quijada’s understated portrayal of Howard’s roommate: as a young medical resident who just needs some sleep, Quijada is quirky and brightly funny. Through 3/13: Fri-Sat 8 PM, Sun 3 PM. Attic Playhouse, 410 Sheridan, Highwood, 847-433-2660. $16 in advance; $18 at the door.
