Emmy winner Kathy Griffin is currently taking Broadway by storm with her one-woman show Kathy Griffin Wants a Tony, but fans who can't make the show's limited run only have to look to TV hit Glee to catch her signature brand of humor. On the March 15 episode, Griffin guest-starred as Regionals competition judge Tammy Jean Albertson. The guest spot gave Griffin the chance to spoof conservative politicians like Sarah Palin and Christine O'Donnell as Albertson railed against the show's gay characters Kurt and Blaine (Griffin herself is a huge advocate of the LGBT community.) Take a look at the clip below which also features original Dreamgirls star Loretta Devine as a not-so-holy nun!
