Frances Conroy has been tapped to join CBS' Mike Birbiglia's Secret Public Journal. The new CBS comedy is based on comedian Mike Birbiglia's weekly life-chronicling blog of the same name. The sitcom will star Birbiglia as - you guessed it - an immature stand-up comedian living with his girlfriend in Brooklyn. Conroy, known best for playing Ruth Fisher in HBO's Six Feet Under, will play Birbiglia's mother. - Adam Bryant
