Nonsense is especially funny when it's grounded in a command of the conventions it violates. In this hour-long sketch show writer-performers Beau Golwitzer and Thom Vacca don't establish that command, so their strange antics seem forced and irredeemably ridiculous. Mediocre acting doesn't help, but the show's greatest defect is the writing. Poor timing exacerbates languid, uninspired dialogue; arhythmic bits just stop rather than conclude; corporate-speak, men touching men, and bullied nerds are assumed to be inherently humorous; and at times the action is simply distasteful, as in a scene involving grown men, a little boy, and pornography. Some sketches--like a mime of Olympic lugers--are clever in concept, and Vacca's talent flickers occasionally, but these strengths can't buttress the flimsy frame. Through 6/30: Fri 10:30 PM, Oracle Productions, 3809 N. Broadway, 773-575-0554 $8-$10.
