All too often plays or films billed as "comedy" are black comedy -- grim, sad and sometimes ironic. And almost always, I don't find them funny. So it was with great delight I enjoyed a real comedy as in you laugh, at GableStage, with its current production "An Act of God". By David Javerbaum, head writer of Comedy Central’s “The Daily Show with Jon Stewart” , it's great fun, light and witty, thoroughly enjoyable all the way.
