TinFish Theatre offers a dull rendition of Neil Simon’s silly comic fable about a village cursed for 200 years with stupidity. Only a few performers go beyond mere competence to provide a few laughs: Dustin Ayers as the eager schoolmaster who can break the curse, Joan McClive as the simpleminded girl whose love keeps him from leaving despite the risk he’ll turn into a dunderhead, and Lucas Schuneman as the schoolmaster’s rival in love. Whatever additional feeble laughs this production nets are thanks to Simon’s foolproof quips. Director Dejan Avramovich does incorporate some physical comedy, but overall this production is unfocused. Accustomed to staging shows in TinFish’s former home, a small storefront, he underutilizes the larger space his now itinerant company finds itself in. Through 7/3: Thu-Sat 8 PM, Sun 3:15 PM. Theatre Building Chicago, 1225 W. Belmont, 773-327-5252. $20.
