Murphy Guyer's The Infinite Regress of Human Vanity, which had its premiere at the Cleveland Play House, manages to skewer the pretentiousness of arts organizations with a cutting social satire in the tradition of Mark Twain and George S. Kaufman. Set at a terminally P.C. theater festival manned by every brand of megalomaniac, the play was a delirious ode to anarchy. It was good to see the Play House triumphantly flex its artistic muscles.
