It may be a one joke play, but it is a very funny joke! Diane Flack's experience as a new Mother, spiced up by the fact that she is a lesbian, is the same experience we all have. Not so funny at the time, but absolutely hilarious after the fact. At times I laughed so hard, tears were running down my face. Other times, it was just a ho hum, been there done that reaction.
But I have to admit that while the play is really just a long stand up comedy routine, and while there is only one joke, the women can really put it over. The structure held up and the laughs kept coming.
