The Generic Parents are characters exclusive to Scholarship Edition. They take part in the mission Rudy the Red Nosed Santa. They were voiced by Dan Van Zant, Lisa Olsen, Matthew Flewlling, Norm "Tubbz" Brown and Rob Nelson.
The only voice actor that can be matched to a specific character is Lisa Olsen, who voiced Karen's mother - this is because she was the only female voice actor and Karen was the only student with a mother rather than a father.
None of the generic parents were given character models. Their dialogue files were all assigned to Ms. Isaacs, and Ms. Isaacs remained offscreen for the duration of the mission to give the illusion of multiple characters.
During the mission Rudy the Red Nosed Santa, as each Generic Kid gets on Santa's lap the parent alternately begs the kid in question to behave, and either thanks or castigates Jimmy depending on whether the photo he took was good enough.
Pedro's father meekly begs him to behave himself and insults Jimmy if he took a subpar picture.
Sheldon's father meekly begs him to smile, and is gushingly grateful when Sheldon actually does.
Gloria's father gushes about her, calling her his princess, and "Glorious Gloria", but is extremely arrogant and rude to everyone else.
Melody's father is the least obnoxious of the five. He proves to be the source of her environmentalism and far-left political beliefs, and even calls her his "green princess".
Karen's mother is distracted by her cellphone and pays very little attention. If Jimmy fails the mission, she loses her connection, gets angry and drags Karen away in a snit.
