Clarice Dubina is a woman Jack Schafer dated briefly in book #77 Dawn and Whitney, Friends Forever. She refers to Jack as "Schaf" Jeff and Dawn do not like Clarice as seen in book #77 when the family goes to a local carnival. Clarice refers to Jeff and Dawn as "children," which makes both of them mad. She talks a lot, which Dawn finds very annoying. Jeff got his own personal revenge on her while riding the bumper cars.
