Absurdism meets gynecology in this outrageous comedy by Tina Howe. Two couples are celebrating a 4-year-old's birthday party. The hosts, who are clearly challenged by the task of raising their horror of a son, somehow think the guests should also embark on parenthood, despite the fact that the guests are professional anthropologists traumatized by witnessing childbirth in societies way beyond exotic. Whether you're contemplating it, doing it, or living with the disastrous consequences, Howe seems to be saying, childbirth is not for the squeamish. This is a play that is guaranteed to make half the audience squirm.
