For fans of NBC’s Parks and Recreation, Happy Days are here again. Henry Winkler (Arrested Development, Childrens Hospital) will be appearing on the show’s season premiere as Jean Ralphio’s (Ben Schwartz) father. This is the second family member to join the Saperstein mishpacha. Last season, we were introduced to Mona Lisa (Jenny Slate), a character that would fit in perfectly with the girls on Bravo’s Princesses: Long Island. Maybe now we’ll understand what type of person could have spawned such loud and irritating individuals. Winkler joins previously announced guest star Kristen Bell, who will play a political rival of Leslie Knope, played by Amy Poehler.
