With Hannah Horvathā€™s new venture into the world of grad school comes a change of scenery and new characters, and guest stars to play those characters.Ā Girlsā€™ fourth season already includes appearances from Jason Ritter,Ā Marc Maron, Gillian Jacobs, and Zachary Quinto, and now HBO has announced that Orange Is The New Blackā€™s Natasha Lyonne, has been added to the mix. Details are sparseā€”and all anyone really knows is that her characterā€™s name will be Rickey, which as most people will soon realize, if they havenā€™t already, rhymes with Nicky, the character she plays on OITNB. Equally entertaining, the news has given almost everyone out there to chance to make a cheesy prison pun.
