Inspired by the infamous septet of sins, this lame revue of obvious sketches and DOA punch lines dares little and accomplishes less. It starts with an interesting premise: God and the Devil invent the seven sins, then God fatally takes the seventh day off during Creation. And the show ends with a merry chorus, 'We Are Your Sins,' that suggests sinners don forms of wickedness like a wardrobe. But in between are 90 ensemble-generated underachieving minutes linking greed to Donald Trump (wow!), pride to Paris Hilton, and envy to participants in a Miss Codependency beauty contest. Too often the sin indulged in here is the eighth: Thou shalt not bore a paying audience. --Lawrence Bommer a Through 3/16: Wed-Fri 8 PM, Cornservatory, 4210 N. Lincoln, 312-409-6435, $15, $7 Wed.
