This would be a good title for a sketch comedy show playfully mocking gender stereotypes. But aside from video projections of some undeniably hilarious early-60s TV commercials–the type that worked Betty Friedan into a lather–this evening from the all-girl Firecracker Show never really goes that route. Which would be fine if the writing were sharper, the direction tighter, and (crucially) the jokes funnier. Alas, Firecracker relies on overfamiliar middle-of-the-road gags involving smarmy ladies’ men, hippie-dippy New Age types, and harried mothers. Thoroughly mediocre and utterly forgettable. Through 10/21: Fri 10:30 PM. Playground Theater, 3209 N. Halsted, 773-880-0932. $10.
