Donna Loren plays The Joker's moll as "Suzie" in the popular two-part Batman episode "The Joker Goes to School" (3/2/66) and "He Meets His Match, the Grisly Ghoul" (3/3/66) on ABC. This clip is the plot set-up where Suzie is the "good girl" head cheerleader. But she's really working for The Joker, played by non other than Cesar Romero. Nick, the Joker's right-hand man is played by veteran actor Kip King (father of Chris Kattan of SNL fame). Batman/Bruce Wayne is played by Adam West and Robin/Dick Grayson is played by Burt Ward.
Some trivia: On the 1966 Batman Message Board, Donna was #1 pick of 'Molls who changed sides and helped Batman". Donna felt that Cesar Romero transformed himself into The Joker character seamlessly. She learned to play her role in a more campy way from him. Most of the garments worn by Ms Loren on Batman were from her personal wardrobe. Ms Loren is currently in the studio again making music.
