Two shows get squeezed into one lumpy mess in this Chemically Imbalanced Comedy late-night offering. Creator Chris Churchill describes it in press materials as "a kid's show for...angry grown-ups." This translates into occasional attempts at clumsy quasi-political commentary delivered by four pajama-clad adults, who also spout irritating non sequiturs and insult one another--their relationships feel like overextended improv riffs. In Tony Mendoza's meandering staging, it's hard to tell what the overarching political message is, other than that George W. Bush is an asshat and that racial and ethnic epithets are wrong (though making fun of people with Down syndrome is apparently OK). Unlike a real slumber party, this gathering can be downbeat to the point of funereal. Some of the sequences might be mildly amusing if you're stoned. Unfortunately, I wasn't. Through 11/19: Fri 11 PM. Cornservatory, 4210 N. Lincoln, 773-865-7731. $8.
