Pippin Parker will stage the Public LAB production, which will officially open May 19 and run through May 29. Knickerbocker is the final production in the 2010-2011 Public LAB season.

In addition to Chaplin ("Spin City," The Petrified Prince), Barron (The Coast of Utopia), Shenkman (Proof, Sight Unseen) and Dishy (Sly Fox, Morning's at Seven), the cast will include Christina Kirk (Well, Clybourne Park) and Zak Orth ("Romeo + Juliet," Major Barbara).

Here's how the Public bills the play: "'Are you ready?' Jerry confronts this question from the womb of his favorite restaurant booth while the months pass by and the son he and his wife Pauline are expecting grows from the size of a peach to the size of...a baby. As the due date approaches, can friends and family members help Jerry feel prepared, or just feel worse, like some un-anonymous sperm donor terrified of making the transition from being the son of a father to being the father of a son?"

The production will have scenic design by Peter Ksander, costume design by Gabriel Berry, lighting design by Jeff Croiter and projection design by Shawn Duan.

Sherman's plays include Things We Want, Sophistry, Veins & Thumbtacks, Evolution, Sons & Fathers, Jesus on the Oil Tank, Serendipity & Serenity, Wonderful Time and Women & Wallace.
