One struggles in vain against the temptation to describe this black comedy as an odd duck. Keith Huff’s cheerfully twisted new piece limns the unlikely relationship between a buttoned-up CPA with some dark secrets and an Irish office temp/cellist who’s been impregnated by her caddish boss. What seems at first an homage to Billy Wilder’s The Apartment soon ventures into Norman Bates territory. Larry Neumann Jr. is delightfully creepy as the bean counter, but in Alex Harvey’s staging, Katlyn Carlson is overly reactive and shrill as the woman, whose character isn’t as well developed. Huff’s gifted wordplay and Neumann’s galvanizing performance, however, focus attention on the piece’s morbid allure rather than its clunky moments. Through 5/13: Fri-Sat 8 PM, Sun 3 PM, Live Bait Theater, 3914 N. Clark, 773-871-1212, $15-$20.
